Growing plumeria from seed

The Basics Of Saving Seeds

What Seeds To Save

While it makes sense to save seeds from flowers and vegetables you normally grow from seed, make sure you’re saving seeds from open-pollinated varieties. With open-pollinated plants, seeds produce plants resembling parent plants. Many heirloom plants are open pollinated.

Start your seed-saving training with plants that have easy-to-harvest seeds, like lettuce, beans, peas, Morning Glories, Four-O’Clocks, Scarlet Sage or Zinnias.

Other tips to know as you save seed:

  • Seeds from hybrid plants don’t produce plants similar to the parents. Check plant tags and seed packets to know if you’re planting hybrids. Learn more about heirloom and hybrid plants.
  • Some plants readily cross-pollinate with other plants of the same type. This list includes corn, gourds, pumpkin and melon. To save seeds from these plants, grow only one variety each season.
  • In cold regions, biennial plants need two growing seasons to produce seeds. In warm regions, fall-planted biennials bear seed the following spring. This list includes beets, cabbage and carrots.
  • Saving seeds means that you’ll have less harvest to eat and fewer flowers to pick, because you’ll be letting plants produce seeds instead.

When To Save

Allow seeds to mature on plants before collecting. Clues for maturity include a hard seed coat and darkened color. Check plants daily when you’re waiting for seeds to ripen.

For seeds contained in a pod, like Cardinal Climber or beans, let seedpods dry on plants and harvest individual pods as they dry. If freezing weather or heavy rains arrive as seedpods are ripening, gather pods for drying indoors.

How To Harvest

For many plants, it’s easiest to collect entire seed heads or pods. Examples include Zinnias, Scarlet Sage, lettuce and broccoli. Plants like Four-O’Clocks or onions produce seeds that are easily gathered individually, since they are already separated from surrounding plant parts.

Separate Seeds From Chaff

Retrieve seeds from the flower head, husk or pod. Often you can do this by rolling the seed head between your hands over a piece of paper. For all but the smallest seeds, use a three-speed fan to blow chaff away.

An alternative method is to build a hand screen by attaching metal screen to a wooden frame. The wire gauge of the screen should permit seeds to pass through. To use, break seed heads apart over the screen, and shake the screen over a large piece of paper. Collect seeds.

Dry Seeds

To dry seeds, spread them on newspaper, paper plates or a screen in a cool, dry place. Dry seeds as quickly as possible to preserve best germination rates. Drying time varies depending on humidity, but most seeds dry in 5-7 days.

How do you know if seeds are dry enough?

  • Dry seeds should be brittle and hard.
  • A properly dried seed won’t bend when you try to break it in half – it snaps in two.
  • Dry beans won’t give when you bite them.

How To Store

Moisture and warmth spur seed germination, so storage conditions should eliminate these factors. Store seeds in paper envelopes, glass jars or plastic bags. Glass is the best choice, since it excludes moisture.

Ideal storage conditions are cool and dry: less than 50ºF with relative humidity less than 50%. Some gardeners add silica gel to seed storage containers to help absorb moisture. If adding silica gel to sealed jars, remove the gel after one week.

For every 10 degrees that storage temperature decreases, seed longevity doubles. Store valuable seeds in glass canning jars in the freezer. Bring jars to room temperature before opening to prevent condensation from forming on seeds.

Cannabis Seeds 101: All You Need to Know and More

What Are Cannabis Seeds?

Cannabis is a dioecious plant, meaning its female and male reproductive organs are found on separate individuals. Female cannabis plants are grown in an environment without males to produce what we find in medical and recreational stores: seedless, high potency marijuana flowers, traditionally known as “sinsemilla.”

In order to reproduce, the flower of a female plant must be pollinated by a male plant after which the female flower produces seeds. However, many varieties of cannabis can produce some male flowers alongside female flowers on the same plant, especially if exposed to environmental stressors or left to flower for a longer than normal period. This is known as the hermaphrodite condition, and sometimes these male flowers will produce viable pollen and self-pollinate the surrounding female flowers to create seeds.

Once the seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they germinate and grow into new cannabis plants the next spring, or they are harvested for processing into hemp seed oil, food products, or to be sown to become the next generation of plants.

What Are Feminized Cannabis Seeds?

Feminized cannabis seeds are seeds that are produced by causing the monoecious, or hermaphrodite condition in a female cannabis plant. This is achieved through several methods:

  • By spraying the plant with a solution of colloidal silver
  • Through a method known as Rodelization
  • Spraying gibberellic acid (much less common)

Feminized seeds produce plants that are nearly identical to this self-pollinated (or “selfed”) female parent plant, as only one set of genes is present. This is sometimes referred to as “cloning by seed” and will not produce any male plants. However, most producers of feminized seeds do not go through the lengthy (and costly) process of identifying a completely stable mother plant for seed production. Many, if not most feminized seeds end up being hermaphrodites, which can result in flowers with seeds in them and reduced yields. Most experienced growers will not use feminized seed, and they should never be used for breeding purposes.

What Are Auto-Flowering Cannabis Seeds?

Most cannabis plants begin their flowering cycle when the photoperiod, or length of time they are exposed to light each day, is reduced to somewhere between 12 and 14 hours, regardless of the size or age of the plant. The species Cannabis ruderalis, however, will begin flowering once the plant reaches a certain age and does not depend on a change in photoperiod.

Some breeders have crossed the low-THC ruderalis with other more potent varieties to create auto-flowering strains. These strains will produce indica, sativa, or hybrid-like cannabis flowers that start blooming as soon as they reach maturity. This is desirable especially in northern climates where summers are short and cold, and wet weather comes early in the fall. Auto-flowering strains can be started in early spring and will flower during the longest days of summer to take advantage of the highest quality light available. Unlike clone mothers, auto-flowering strains cannot be kept in a vegetative state.

What Is the Difference Between Cannabis Seeds and Cannabis Clones?

A clone is a cutting taken from a plant and then placed in some sort of grow medium to induce root production. Once it has rooted, it can be grown into a mature plant that is genetically identical to the one it was cut from.

Seeds carry genetic information from two parent plants that can be expressed in numerous different combinations, some like the mother, some like the father, and many presenting various traits from both. Creating identical cannabis plants using seeds is a very difficult and lengthy process. Generally, cannabis producers will plant many seeds and choose the best plant, and then take clones from that individual to grow their cannabis flowers, or simply start with a proven clone acquired from another grower as their mother plant.

Where Can I Buy Cannabis Seeds?

Cannabis seeds can be found on numerous online seed banks, many of which are located in the UK, the Netherlands, Spain, and Canada, where the laws on selling cannabis seeds are much more lax than in other countries. It is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person. In states that have home-grow provisions in their medical marijuana laws, you may purchase seeds at dispensaries. Seed banks are popping up in many of these states.

What Is the Legality of Cannabis Seeds?

Depending on what state you live in, it may or may not be legal to sell, purchase, or possess cannabis seeds. In the United States, all cannabis seeds are considered illegal at the federal level.

Seed banks exist outside of the US and can sell them for “souvenir purposes,” but it is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person.

What Makes a Cannabis Seed High Quality?

There are several factors that go into determining whether cannabis seeds are high quality or not. First of all, they must be allowed to fully mature before harvest. Next, they must be properly stored as to not acquire mold or other pathogens that can spoil them. Seeds should be stored in a dark, cool place and used within 16 months, or frozen for future use.

The most important factor in seed quality is genetics. To grow quality cannabis, you need good genetics. Some less scrupulous breeders will simply cross a nice female with a random male and sell the resulting seeds. Other breeders will take their time crossing and backcrossing plants to stabilize the most desirable traits, while still producing an array of different phenotypes. This group represents most of the seeds on the market.

Really dedicated breeders have worked for years to create “inbred lines”, or IBLs, that will produce plants with very little noticeable difference. IBLs represent only a small fraction of the cannabis seed market, as they are generally used by breeders and not by cannabis producers.

How Do Cannabis Seeds Germinate?

In the wild, female cannabis plants drop their seeds as they die in the fall, then when the warmer, wetter weather of spring comes around, these seeds sprout and become new plants. Traditional outdoor methods used for centuries involve simply broadcasting seeds by hand onto cultivated fields.

There are many methods used by modern growers to germinate seeds. The easiest is to put the seed in a light potting soil mix covered by ⅛ to ¼ of an inch of soil. Keep the soil moist and relatively warm (50-70 degrees Fahrenheit) until the seed has sprouted into a seedling. Other techniques involve lightly scuffing the seed coat to ensure the seed is able to crack open, pre-soaking the seeds, and even germinating them in a wet paper towel until the epicotyl emerges and then gently planting them in the grow medium with tweezers. There are also popular products called starter plugs that consist of a small block of growing medium, often compressed peat or coco coir, with a small hole in the middle into which the seed is placed.

What Is There to Know About High-CBD Seeds?

Cannabidiol, or CBD, is one of the chemical components (known collectively as cannabinoids) found in the cannabis plant. Lately much has been made of the potential benefits of CBD for treating the symptoms of many diseases and conditions. Through millennia of human selection for high THC content, cannabis with high levels of CBD has become exceedingly rare, as the genetic pathways through which THC is synthesized by the plant are different than those for CBD production.

Cannabis used for hemp production has been selected for other traits, including very low THC content, so as to comply with various drug laws. Consequently, many varieties of hemp plant produce significant quantities of CBD. As interest in CBD as a medicine has grown, many breeders have been breeding cannabis that has high levels of CBD by crossing drug species with hemp species; some of these hybrids have little or no THC, some have 1:1 ratios, and some that still have high THC contents along with significant amounts of CBD (3% or more).

Seeds for these varieties are now widely available online and through medical dispensaries. It should be noted, however, that any plant that is grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. There are breeders who are currently working on making seed strains with consistent CBD levels, but until these seeds are widely available, a grower who wants to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or grow many seeds out to maturity and have samples tested at a lab to determine the cannabinoid levels of each.

Why Are Cannabis Seeds So Expensive?

Cannabis seeds generally sell for about $10-$12 each, a far cry from the $3 pack of tomato seeds you can buy at the local nursery. People are often quite taken aback when they find that a pack of 10 cannabis seeds can cost well over $100. It’s not hard to pinpoint the reason for this: prohibition.

The breeding of commercial crop seeds can be done in a relatively short time because of the enormous scale and abundant resources of commercial breeding programs. The general rule is that if you can grow more plants at once, it’s easier to locate and stabilize desired traits and is less expensive to produce massive quantities of seeds. Add to this new scientific methods of testing for desired traits using tissue cultures and lab analyses, and you have a great advantage over your average cannabis breeder.

Even larger scale cannabis grows are miniscule when compared to your average commercial agricultural seed production facilities. Cannabis breeders working under prohibition or strictly regulated legal environments are simply not able to work on this scale, and must take much longer, sometimes as long as decades, to produce a quality seed line. When you combine this restriction with the threat of potential legal consequences for breeders (many have spent time in jail), it becomes easy to see why cannabis seeds are so expensive. It should be noted that high cost does not always equal high quality, as the industry is unregulated.

This does not mean that those chosen to pollinate will be the largest plants. Rather, the selection of both males and females will depend on their capacity to adapt to their growing environment, those that are the most vigorous and productive. For example, those that have adapted best, suffered least, are the most potent, have developed the most, and required the least nourishment. Details should also be sought in the plant’s structure; for example, those that present short distances between nodes, and other traits important to growers, such as their smell, taste, and resistance to mould and pollutants. Once the selection has been completed, separate the males in a different and sealed space or cabinet in order to prevent any type of pollen contamination.

One must remember that the male contributes about 25% of the plant’s final genetic material. Hence, until the crossing is carried out the grower will not know the final composition of his seeds. But what one always looks for, in order to get as many as possible, is a strong male with lots of flowers at the tip, and buds presenting dense pollen, as the prime objective is for a single male to be able to impregnate the greatest possible number of female plants.

Step 3: Obtaining pollen

As a reference point, from the point at which the male begins to flower until its first flowers open, releasing pollen, some two to three weeks transpire. In just 10 days, however, one can begin to see those “little eggs” (which are nothing but male flowers), while the first stigma of the female plant also come into view.

The development of the male’s flowers is progressive. First the flowers gradually turn yellow, changing from their original green colour. When the first male flowers begin to indicate that they are about to open, it is a good idea to turn off the fans in your grow room, while maintaining the air circulation, to keep the humidity from rising. Moving air can lead to the loss of pollen from the first flowers that open. About 10 days later most of the male plant flowers have yellowed, and then you’ll have to reduce your watering, without drying the plant, but without excess water either, as moisture helps flowers open faster.

When the male plant is mature, the flowers open their sepals, exposing the stamens and releasing pollen into the air. This is when you should proceed to pollinate, because if you wait three or four days the pollen can significantly lose its fertility. Remember that when the moisture level exceeds 75% the pollen starts to die quickly, so it is best to keep it as dehydrated as possible.

Step 4: Cutting the male flowers

Pollination can be done by cutting parts of the male plant at the peak of their maturity, or using the whole plant to spread the pollen on the female plants. If you choose to cut it, to handle it better and carry out a more controlled pollination, you must take into account a number of conditions. Don’t overdo it with the scissors: just cutting some flowers will be enough to produce hundreds of seeds.

With tweezers, select the most mature flowers (which will present a more intense yellow colour) and leave them one or two days in a glass bowl or plate, in order to let the pollen dehydrate. Another option is to hang the flower upside down and let the pollen fall into a container, if you don’t want your table spattered with yellow powder. After that, tap the flowers gently with tweezers so that the rest of the pollen falls and the stamens are devoid of powder.

Step 5: Conserving the pollen

To maintain the properties of the pollen every grower has his own tricks, but all are based on achieving the maximum dehydration of these particles. Conserving them calls for controlling the humidity and temperature, as these variations can damage their reproductive qualities.

Also, if you have acquired a generous amount of yellow powder, you can also store it in the freezer in order to carry out future pollinations. Yes, pollen can be frozen, and stored for months. To do this you just need to use a good jar, and keep it from getting damp when you take it out of the cold. One way is to leave the jar at room temperature a few hours before opening it. This is important, because if the pollen comes into contact with moisture, the whole process will be ruined.

Step 6: All ready to pollinate in a controlled manner!

Females are ready to be pollinated after their early flowering stage, and when they have developed large heaps of flowers forming buds of a decent size. The best time to pollinate the female is when the flowers have fully-formed stigmas (the little white hairs), as long as possible, usually four or five weeks after the beginning of flowering, or 25 to 35 days, always depending on each strain. There are even strains that can be pollinated 20 days after flowering has begun.

But remember that the times for male and female are different, because the male flowers before the female does: as a general rule male plants tend to mature about two weeks earlier than females. With this temporal divergence, day 30 of flowering to pollinate the female is day 45 for the male, which is how long it takes to have the greatest amount of pollen: the more pollen the male has, the more likely it is to pollinate the female, and the greater the final number of seeds.

The application of the pollen is very simple: if you have cut flowers and saved the pollen, with the help of a brush, a cotton ball, or even your fingers, sprinkle it on the feminised plant. Do this repeatedly for two or three days.

In this regard, it is important that the pollen not reach the buds of the lower parts of the plant, or its willowy parts. Nor is it advisable to pollinate complete buds, but rather the parts that retain the white, most receptive stigmas. It is also useful to prune all the flowers that have not been pollinated, as in this way the energy is concentrated on the buds that really matter to you, and the plant does not waste resources on parts you are not going to use. In this “artisanal” way, for low volumes, you will obtain several hundred seeds without any problem.

Step 7: What if I want a lot more seeds?

You must remember that there is nothing better than fresh pollen taken straight out of male flowers. So, another form of pollination is to directly grab a male plant and shake it on the females. You can use a small stick to tap the branches of the male so that its pollen falls on the buds and produces fertilisation with the help of gravity.

It is important to turn on your fans before shaking the plant so that the pollen goes everywhere before falling to the floor. The temperature of the room where pollination occurs should be 24° C, with humidity no greater than 65%, as the hotter it is, the less oxygen per cubic meter of air, allowing the specks of pollen to remain suspended in the air longer.

The pollen, once it touches the stigmas of the female plant, still takes 3 to 5 days to reach the calyx and the ovary, and for fertilisation to occur. So, once you have carried out the first pollination, return the female plant to its place, irrigate it after 3 or 4 days, and pollinate it again, just in case. As what we are after is the greatest pollination possible, some growers finish the process by shaking the females too at the end so that all the pollen that has stuck to the leaves can reach the buds below. In this way thousands of seeds can be obtained per plant, rather than the hundreds of seeds achieved manually.

Step 8: Harvesting seeds

If the process has been carried out properly, in just a few days you will see the seeds begin to grow inside the calyx of the female flowers. Once the plants have been pollinated, most of the seeds will take 4-6 weeks to fully mature (always depending on the strain). At the end of flowering period they will be ready to be harvested, so that you can enjoy another pleasant cannabis harvest. This is just when the seeds begin to darken, going from green to brown or dark grey, and the calyces begin to open so they can easily get out.

You can test the seeds to determine whether they are mature, and how hard their hard shell is, by taking one and pinching it between your fingers to see if it breaks. Seeds with stripes and other patterns are usually a good indicator that they are mature, but remember that not all strains produce stripes on their seeds. And bear in mind that the seeds of different genetics can be of different sizes: some strains can offer you seeds that are smaller than normal, and this could be misinterpreted as a sign of immaturity.

And, as always, remember that one of the basic rules is to use sterilised tools, and keep good records on the dates and details of the strains you have decided to work with. With these simple tips, you can now get down to work and start pollinating your cannabis plants.

Why Soak Plumeria Seeds

Soaking seeds before planting is an old-time gardener’s trick that many new gardeners are not aware of. When you soak seeds before planting, you can test the viability and significantly decrease the amount of time it takes for a seed to germinate.

Reasons for Soaking Plumeria Seeds

What happens to plumeria seeds when you soak them? Why should you soak plumeria seeds?

In the wild, a seed can expect to encounter harsh heat and cold, very wet or dry conditions and may even need to survive. Plumeria seeds have developed over millions of years with defenses to survive awful conditions. But in your modern day garden, a plumeria seed is pampered. Soaking seeds before planting helps you to break down the seed’s natural defenses against what it expects from Mother Nature, which then allows it to germinate faster.

Another reason is that while Mother Nature actively assaults seeds, she also gave those seeds an internal gauge to help them know when they should grow. For most seeds, moisture levels play a big role in alerting a seed to optimal grow times. By soaking the seeds, you can quickly boost the moisture content around the seeds, which signals to the seed that it is now safe to grow.

And lastly, soaking a plumeria is a good way to test the viability. If the seed plumps up after several hours you know it is a good chance that it is still viable. In nature with natural rainfall, this process can take some time. But when you soak your seeds, this process is sped up and only take a few hours or overnight.

How to Soak Plumeria Seeds before Planting

Seed soaking, at a basic level needs two things: seeds and water.

Some methods for seed soaking may substitute the water for a solutions with Super Thrive or B1. The addition of vitamins to the solution are meant to enhance the germination process and give the seed a stronger start. But these solutions are not necessary in most cases. For most seeds, water will work just fine.

Take a small bowl and fill it with water from your tap, as hot as your tap will allow.

Once your bowl is filled with hot water, place your seeds inside the bowl, then allow the seeds to stay in the water as it cools down. Common questions at this point include “How long should seeds be soaked?” and “Can you over soak seeds?” Yes, you can over soak seeds. Too much soaking in water and a seed will drown. It is recommended that you only soak most seeds for 8 to 12 hours and no more than 18 hours. The seeds of some species of plants can survive longer soakings, but you should only do this if the specific instructions for this species recommend so.

There are things you can do to improve how well your seeds react to soaking. Large seeds or seeds with particularly hard coats can benefit from scarification before soaking. Scarification means to damage the seed coat in some way so that the water is better able to penetrate the seed. Scarification can be done through several methods. These include rubbing the seed on fine grain sand paper or nicking the seed coat with a knife.

After soaking your seeds, they can be planted as directed. The benefit of soaking seeds before planting is that your germination time will be reduced and you can see which one are most likely to germinate, which means you can have happy, growing plants faster.

Plumeria Seeds

When germinating plumeria seeds at home or in a greenhouse, the first thing to remember is plumeria seeds may be started indoors, but should be transplanted and moved to a location that provides plenty of light as soon as it has 3 or 4 real leaves. Leaving a seedling in small containers may result in disrupted growth, which can lead to unfavorable results. However, starting plumeria indoors is a great way to get an early jump on the outdoor growing season. When choosing a medium in which to germinate plumeria seeds, look for one that says something along the lines of, “seed starting mix.” This type of growing medium will likely have a moderate elemental fertilizer charge, which will benefit the newly sprouted seedlings. Seeds can be germinated in many different styles of trays and containers, so choose the type that best fits your space needs. If starting just a few seeds, a simple, flat starting tray or small individual containers will work great. When planting many seeds at once, it may be wise to use trays that are divided into separate growing chambers. This will cut down on the amount of transplanting needed as the plants grow. Remember, all a plumeria seed needs to germinate is warm temperatures and moisture. Some growers do use heat pads underneath the starting trays. Most plumeria seeds will germinate at temperatures between 65-90 degrees Fahrenheit and the added warmth in the growing medium can speed up the germination process. Using supplemental lighting, like a T5 fluorescent bulb, can also help provide extra heat. Though seeds may not need light in order to germinate, the seedling will need light, so having a light source ready is a good idea. I would use caution when starting seeds in a bright window sill because direct sunlight through glass can alter the intensity and the seedlings may stretch and become ‘leggy.’ (There are many good plumeria seed germination methods, I suggest you research each one and use the one or ones that fit you situation.)

When preparing to germinate seeds indoors it is a good idea to soak the seeds overnight or at least 4 hours in a warm place. Also moistening the growing medium before planting any seeds. This will help to ensure that the medium is not over saturated or water logged and that the moisture is spread evenly throughout. Using a tray, spread the seeds so they have about an inch between each, this will help minimize the root damage when transplanting. I have found using plugs is much easier to handle and preserves the roots when transplanting. There are many good planting methods and you should examine each to see which fits your situation and may help result in higher germination rates. If planting is occurring in a flat starting tray, space seeds at least an inch apart, either in rows or in a grid pattern and cover lightly with 1/4″ of growing medium (remember oxygen is important during germination, so don’t pack the medium down to much). Then, spray the entire tray lightly with a hand held mister. The soil should be kept moist not wet long enough for the seeds to germinate, it may need to be sprayed with the mister occasionally to maintain even distribution of moisture. Some growers use starting trays that have plastic, hood-type lids. This will keep the humidity around the seeds at higher than average room levels and may help increase the chance of successful germination. Be sure to check the seeds daily to maintain an optimal environment.

Environmental Considerations

As the plumeria seedlings begin to pop up through the soil, there are a few environmental aspects that should be given proper attention right away: light intensity, humidity, and air flow. Remember the seeds of different cultivars may germinate in different lengths of time. Usually plumeria seeds will germinate in 5-10 days, but I have seen it take up to 30 days if conditions aren’t right. Plumeria seeds can sprout in total darkness, but, once the seedling breaches the soil, a sufficient light source is imperative. Those first “true leafs” will need a light source to perform photosynthesis and create carbohydrates, which will help sustain both normal plant growth and, most importantly, root growth. Without proper lighting, the early vegetative growth of a plant can be negatively affected and could cause long lasting problems.

Humidity can be helpful during the initial germination process but, as the seedlings begin to grow, high levels of humidity can spell disaster. As internal process burn up the seedlings energy sources, the plants will need to release oxygen as a gas through their stomata (a process called transpiration). As the oxygen leaves the plant, water and elemental nutrients are pulled up through the roots. In a humid environment, the stomata will remain closed and the roots will not take in water. If the growing medium is wet without proper aeration, the water will have nowhere to go and the roots will likely suffocate and die.

Air flow and humidity almost go hand in hand. A nice flow of air through the plants canopy will encourage the flow of carbon dioxide to the leaves and, subsequently, oxygen away from them. This is not just true for seedlings, but for plants in all stages of growth. A small fan on medium or low can help keep humidity levels low and the heat from any supplemental lighting to a minimum. Be sure to keep the rooting medium moist, but not too wet. Seedlings need water and going to long without can result in serious damage. However, if the medium remains too wet for too long it may impair root growth. As the seedlings grow, they will eventually exhaust any nutrient charge that the growing medium had to offer, so light fertilization may be needed while waiting to transplant into a different container.

As the seedlings grow, with proper care and attention, they inch closer and closer to fulfilling their own unique destiny. Every plumeria seeds has it’s own DNA structure and will not be exactly like any other. As we stand by, eagerly awaiting the flowers of our labor, it is important to remember that every plumeria we grow has entered into this life as a small, almost insignificant looking thing, that so many refer to as simply, just a seed.
