From the University of Connecticut, Biodiversity Education & Research Greenhouses – Describes Crassula perforata as, “Small shrub with branches to 60cm; greyish green leaves, not caducous, to 2 cm long, constricted towards base and fusted to the opposite one; whitish flowers.”

From Wiley Online Library – Leaf Epidermal Hydathodes and the Ecophysiological Consequences of Foliar Water Uptake in Species of Crassula from the Namib Desert in Southern Africa – This interesting article describes the research and results of studying the leaves of Crassula and their ability to absorb water on the leaves. The study found, “In summary, the results of this study unequivocally indicate that many plants in the genus Crassula are capable of absorbing water deposited on their leaf surfaces, and, furthermore, that this absorbed water may subsequently stimulate CO2 fixation rates, even in tissues distant from those wetted. The ecological implications of these findings are obvious given the environmental conditions commonly found in the Namib Desert where all these species were originally collected. It appears likely that the combination of extreme aridity and frequent nighttime fogs, accompanied by heavy dewfalls, constituted a powerful selective force in the evolution of these plants. Absorption and utilization of water condensed on the shoot surfaces of these species should enhance the survival of Crassula species during extended periods lacking rain but with frequent dewfalls or fogs. Field confirmation of these laboratory findings and extrapolations is necessary before the ecophysiological significance of this phenomenon is fully understood.”

Under “Leaf Thickness” it mentions, “In some species, e.g., Crassula perforata, these diel changes were surprisingly large, constituting nearly 20 % of the minimum leaf thickness measured. Despite the daytime increases, thicknesses of all leaves decreased on a net basis after each 24-h period.”

From a distance, Crassula Perforata a unique succulent appears like green, spiral pasta noodles. Crassula Perforata, , is a hardy plant and a real conversation starter.

The plant belongs to the large Crassula family of plants and comes to us from South Africa.

Due to the distinct green foliage that grows from the flowing stems, the Crassula Perforata also goes by a couple of fitting common names:

  • String of buttons succulent
  • Necklace Vine plant
  • Pagoda plant

The necklace plant is suited for indoor growth, as it doesn’t require a lot of light and can tolerate drought.

It’s an excellent plant for adding more character to any room, but there are a few plant care tips to follow, these are shared below.

String Of Buttons Crassula Perforata Care

Size and Growth

The necklace plant may grow a few inches each year. In the wild, the long stems may reach up to 30′ feet in length.

When grown indoors or in a container, they may only reach four to six feet.

The plant has a strong root system, is fast growing,with sturdy stems spreading outward, producing thick, square-shaped foliage.

The succulent foliage has a distinct appearance. When viewed from a distance, they look like small spirals.

Some people describe them as beads or buttons, which is why it’s called the necklace plant or the string of buttons.

Flowering and Fragrance

The string of buttons does produce flowers. However, they are small and have no scent.

The flowers are typically only a quarter of an inch in size. These small, star-shaped pink or pale yellow flowers bloom in the spring.

Keep in mind that this plant doesn’t always flower. If spring comes and goes without flowers, it doesn’t mean that the plant is dying.

Light and Temperature

The necklace plant is recommended for USDA hardiness zone 9 to 11. It doesn’t tolerate freezing temperatures or extreme humidity.

Outside of the American Southwest, it should be grown indoors.

Temperatures in the 60s and 70s are recommended throughout the year.

If possible, give the plant indirect sunlight (partial sun) throughout the day.

When placed indoors, any window other than a south-facing window with direct sunlight should work fine.

In an outdoor setting, ensure that the plant gets at least four hours of solid, bright sunlight.

Watering and Feeding

Like most succulents, the necklace plant can retain water. It doesn’t require frequent watering.

In fact, it’s a good idea to let the plant dry out between watering.

If necessary, add liquid fertilizer every two weeks throughout the growing season. The fertilizer should be diluted to one-third strength.

Soil and Transplanting

The necklace plant requires soil with good drainage. Standard potting soil with added sand should offer the right conditions.

Transplanting is needed if the plant outgrows its current container. Repotting is also recommended every three years, to get rid of the old soil.

If transplanting is necessary, the plant should get moved in the early spring, just before the active growing season starts.

Maintenance and Grooming

To manage the growth of the plant, trim it back. The easy to grow plant can be trimmed any time of the year if the stems start to get too long.

Propagating Necklace Plant

Propagation is possible using side-shoot cuttings. Take the cuttings from one of the stems, removing a piece that is about four inches long and contains several of the succulent leaves.

Allow the cuttings to dry for two to three days. Plant the cuttings in the same soil used for the mother plant. It should offer good drainage. Adding a little sand to regular potting soil is recommended.

The new plants should be placed in a bright spot. Within one to two months, the cuttings should take root and be strong enough to transplant to individual containers.

Ensure that the young plants remain hydrated, but not overwatered.

String of Buttons Pests or Diseases

While the thick succulent foliage of this plant should make an attractive habitat for insects and pests, the plant is rarely attacked.

It’s a hardy plant with no major threats, other than overwatering. If the plant is overwatered, rot may develop.

Rot typically starts at the base and works its way through the stems. This problem is more common in cooler regions or during the winter when it doesn’t get as much sunlight.

To reduce the risk of rot, allow the plant to dry between waterings. If rot is detected, cut it away and scale back the frequency of watering.

Suggested Crassula Perforata Uses

The distinct appearance of the crassula perforata makes it a great houseplant. It can be grown from a hanging plant or allowed to spill over a window box or individual pot.

For optimal growth, move it outdoors during the warmer months and indoors during the winter.

In warmer regions, it may be planted outdoors in a garden bed where it can provide unique ground cover.

How to Grow and Care

Crassulas are easy to grow, but they are susceptible to mealy bugs and fungal diseases. As with all succulents, overwatering is sure to be fatal, so err on the side of too dry rather than too wet. Never let your plant sit in water. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes.

These succulents are generally started by division, offsets or leaf cuttings. Crassulas can be easily propagated from a single leaf. Sprout leaves by placing them into a potting mix for succulents, then covering the dish until they sprout.

Repot as needed, preferably during the warm season. To repot your Crassula, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.

Crassula Perforata ‘String of Buttons’ Care and Propagation

Frost Tolerance

Crassula Perforata can tolerate mild frost and freezing temperatures as long as they are not for long periods of time. If you live in USDA hardiness zones 9-11, you can leave the plant outdoors all year long and they can even be planted in ground. As I mentioned above, I keep mines outdoors all year long, and they survive the freezing rain and frost we experience in winter time.

If you have extreme winter conditions in your area, the best way to grow these plants are in containers. That way you can bring them indoors during winter or when there is forecast of frost or snow. In case you can’t bring them in, there are ways to protect the plants from frost and freezing temperatures outdoors. You can use frost cloths or mini greenhouses to help them survive the cold winter. Here are some of my recommendations for frost protection.

For more information on this topic, do visit my post on “Optimal Temperatures for Succulents to Thrive”.

Soil Requirements

Crassula Perforata needs a well draining soil. The right type of soil goes hand in hand with proper watering. I have been using a simple, tried and tested concoction that has worked well for my plants. I like to use a cactus potting mix combined with perlite for added drainage. I do not use exact measurements but eyeball it to about 2:1 solution of cactus mix and perlite. Others recommend using a sandy soil. This can be achieved by mixing cactus mix or potting soil with coarse sand (about 2:1 ratio). I get most of my materials from a local hardware store. You can also purchase them online. Here are my soil recommendations. To read more about soil for succulents, click on “Best Soil and Fertilizer for Succulents” to get more useful information.

Watering Requirements

Watering largely depends on the climate you live in. Although these plants are highly adapted to dry weather conditions, they do much better when given sufficient amounts of water. There really isn’t a set schedule or formula on when to water succulents. My watering schedule is dictated by the very dry climate I am in.

In the summer months, I water my Crassula Perforata as often as every 7-10 days, sometimes more during a heatwave. I cut back on watering to about every 10-14 days when the weather cools down. During the winter season, I mostly rely on rainwater and hold back on watering altogether because this is when we get a lot of rain in my area. But if we don’t get any rain at all during winter then I water at least once a month or every 2-3 weeks, depending on how dry the soil gets.

For those people in humid locations, you won’t need to water as much. And if you keep your plants indoors, you may not have to water as much especially if they are not receiving a lot of light. Too much water and not enough light is a recipe for disaster for these plants.

One good way to tell whether it’s time to water is to check the moisture of the soil. The top inch of the soil needs to feel dry before you can water again. If you are unsure how much and how often to water in the beginning, it’s always better to underwater and increase watering as needed. Pay attention to how your plant looks and you can adjust watering accordingly.

For further help with watering techniques, consider using tools like hygrometers or moisture meters to check for moisture in the soil and air. These tools are pretty affordable and can come in handy especially if you are unsure of when to water your plant next. I have narrowed down the choices here on my resource page. Do visit the page if you need help in gauging your watering needs.

Useful Tip: When watering, water the base of the plant or the soil area and avoid watering from the top of the plant to prevent leaf rot. The way Crassula Perforata plants are shaped, water can collect on the leaves and when they stay wet, rot starts setting in on the leaves.

All About String of Buttons

Crassula perforata, also called Pagoda Plant or Necklace Vine, is a fast grower. It shoots up and out in the spring and fall and goes dormant in the summer. The stems clump together like a shrub and grow over other plants. They will even grow through neighboring bushes.

When matured, your Necklace Vine might surprise you with some flowers in the spring. These small, star-shaped beauties grow in clusters of yellow, white, or pink. To increase the chances of flowering, give your plant a slight night and day temperature difference. It also needs a colder, but above freezing, winter temperature.

Because it’s native to South Africa, Crassula perforata needs a warm climate. If you live in zones 9-11, you’re one of the lucky ones who can grow this plant outside year-round! Don’t worry if you live in a colder area though because it makes a great houseplant as well.

Types of Crassula Perforata

The Crassula genus has over 300 species! Many of these species share common names, such as ‘String of Buttons’. Because of this, it can be tricky to track down exactly what you’re looking for. To help, here are two common varieties of the Perforata species.

Crassula perforata Variegata, ‘Variegated String of Buttons’, ‘Variegated Necklace Vine’

The word ‘variegated’ means having different colors, so you can imagine how this one stands out. The Variegata variety has a myriad of colors from green to yellow to pink. Some have rainbow-esque edges and others are striped.

Crassula perforata ssp. Kougaensis, ‘String of Buttons’, ‘Necklace Vine’

This subspecies is pretty standard looking. The leaves feature vibrant, reddish-pink edges. They’re also speckled with pink or white dots.

Crassula perforata is frequently confused with Crassula conjuncta, which has slightly different leaves. Their care is very similar, but we will only refer to the Perforata species in this article.

Pagoda Plant Care

The Pagoda Plant has typical succulent needs. Once you get the hang of it, this low-maintenance plant is fairly easy to care for.

Light & Temperature

Your Necklace Vine plant needs 4-6 hours of partial sun with partial shade. The more sun it gets, the more vibrant its color will be. However, direct sun and high heat can easily burn the leaves. You can balance this by choosing a spot that gets shade around 2-3 PM but is otherwise sunny. Another option is planting it where there is filtered or indirect light. If you’re growing this succulent indoors, choose an East, West, or South facing window.

Crassula perforata is sensitive to sudden light or temperature changes. When making any adjustments, always do so gradually so your plant can acclimate properly.

Temperatures below freezing are usually too cold for Crassula perforata. If you’re growing indoors because of this, keep the temperature around 65-70° F during the summer. In the winter, this plant prefers temperatures around 50° F. You don’t have to freeze yourself though! Just move the succulent away from heating vents and it should be fine.

Water & Humidity

It’s very important not to overwater succulents, and Crassula perforata is no exception! They don’t need lots of water because they have water storage in their leaves. Too much will make the succulent soft and mushy. If you underwater though, the plant will droop and the leaves will shrivel.

Water this plant only when the soil is completely dry. If you’re not sure if it’s dry or not, don’t water it. Any kind of succulent is much better off being underwatered than overwatered.

String of Buttons doesn’t like high humidity. To keep it happy, only water it at the roots and keep it in a well-ventilated space.

Well-draining soil is an absolute must for Crassula perforata. If its roots are sitting in water, they can easily start to rot. Store-bought cactus and succulent soil drain well. You can also mix perlite or sand into potting soil. Remember to periodically check that the soil is draining well. If it’s holding too much water, mix in more sand.

Necklace Vine isn’t picky about pH levels, but grows best in 6.0 (slightly acidic).

Fertilizer

Fertilizer isn’t required but will help with growth and flowering. If you choose to, use ⅓ to ¼ strength liquid fertilizer every other week during the growing season. If your Crassula perforata is young, use a low nitrogen fertilizer. Mature plants are fine with a balanced 20-20-20.

Controlled release succulent fertilizer is a good alternative to liquid. This should be applied only at the beginning of the growing season.

Repotting

Repot your String of Buttons when it outgrows its container. This succulent grows a few inches each year, so choose your pot size accordingly.

It’s recommended to repot String of Buttons while it’s dormant and in warm weather. Then it will have lots of space when the growing season starts!

If you find any rotting roots while repotting, trim them off and let the cuts dry before planting. Change the soil to one that drains better.

Propagation

Crassula perforata can be propagated from cuttings, division, and offsets.

Propagating from Stem or Leaf Cuttings

For stem cuttings: Cut off the top inch or more of a healthy Necklace Vine, then remove the bottom leaves so at least half an inch of the stem is bare.

For leaf cuttings: gently remove the leaves without leaving any part on the stem.

Because Necklace Vine leaves grow in sets of two, you can gently twist them on the stem so they break off in one piece. Let the wounds on your cuttings dry out for a day or two. Once they’re ready, it’s time to plant!

Plant your cuttings in well-draining soil. Stem cuttings can simply be inserted in the soil. Leaf cuttings can be laid on top. Mist the cuttings with water and keep them out of direct sunlight until they’re rooted. Rooting hormone is optional but helpful.

Once your cuttings are settled in, gradually increase the light they receive. Water them normally at least once a week, until the plants are matured.

Propagation from Offsets

This method follows the same procedure as cuttings. Offsets are rosettes on long, thin stems that the plant sends out above ground. Cut them off an inch below the rosette.

If your String of Buttons is getting too large, you can literally split it in two! Gently remove it from the soil and dust off the roots. You’ll see that this plant is really a clump of many stems and roots. Break the plant in two with your hands or a sterile knife. Replant them in dry soil and don’t water them for a few days. If the wounds don’t dry out, they can rot or get infected when watered.

Pruning

Pagoda Plant can be pruned for cosmetic reasons. When the flowers die, they leave behind long, woody stems that are easy to remove. You can also prune back the plant if it’s getting too large for your taste.

When pruning, make clean cuts with sterile clippers. Keep the area dry so it won’t grow bacteria while healing.

Troubleshooting

Crassula perforata has its share of problems just like every other plant. That’s why preparedness and a sharp eye is vital for keeping your succulent happy and healthy.

Growing Problems

Etiolation is when a plant stretches out in search of light. Because succulents are valued for their plump and compact leaves, this can mess with their look. If your Pagoda Plant is starting to stretch, gradually move it to a sunnier spot. If the plant is already stretched more than you like, you can prune back the long stems.

In the summer, you may find brown spots on the leaves. This is usually sunburn caused by too much heat and direct light. If you adjust the plant’s location right away, the damage will most likely be external only. Crassula perforata should be moved gradually so it can adjust to the light difference.

As mentioned, shriveled leaves and a drooping plant are symptoms of underwatering. Mushy, brown, or translucent leaves usually mean you overwatered. Adjust your watering and soil as needed.

Pests

Aphids are tiny pests in a variety of colors. You’ll usually find them on the underside of leaves – their food sources. The honeydew they secrete can grow black mold and attract ants. If there’s a large number of aphids in one spot, you can simply prune the leaf. Insecticidal soap and orange guard spray will control them also. To prevent aphids, try using Diatomaceous Earth, neem oil, or Ladybugs.

Crassula perforata is also susceptible to Vine Weevil, a flightless black beetle. These pests are nocturnal, but the damage is clear during the day. You’ll see C-shaped holes and wilted, yellow leaves. Sprinkle Diatomaceous Earth or grits at the base of the plant to prevent them. Because Vine Weevil is fairly resistant to sprays, remove them manually at night.

Mealybugs are another pest to watch out for. They’re small, white bugs that drain the sap from plants. Remove them with insecticidal soap or a mix of liquid dish soap and water. You can also attack them individually with a q-tip dipped in 70% rubbing alcohol.

Diseases

Root rot is the most common threat to String of Buttons. It usually starts at the roots when the succulent is overwatered. You may also see it in the stem and leaves. Rotted sections will turn brown or black and be mushy. Root rot makes them more susceptible to bacteria, so they need to be treated early on.

Remove root rot by cutting off the infected sections. Let the wounds callous over before replanting in new, well-draining soil. After replanting, don’t water your Pagoda Plant for a few days so it can recover.

If your Pagoda Plant’s roots are too rotted to save, take a cutting from the top to propagate. Then you’ll get a fresh start with this succulent!

FAQs

Q. Is Crassula perforata toxic to pets?

A. Neither PetMD nor American Veterinarian list String of Buttons as toxic to pets.

Q. Can you save an overwatered succulent?

A. Usually, you can! Repot the succulent in new and completely dry soil. Remember to brush off the old, moist soil from the roots first. Don’t give the plant any water for a few days or until it recovers.

Q. Why are the leaves falling off my succulent?

A. Old leaves at the bottom of the succulent fall off naturally. If newer green leaves are dropping, you’ve probably overwatered.

Crassula perforata – String of Buttons

String of Buttons (Crassula perforata) (Thunberg): One of the best-loved stacked Crassula species with alternating, triangular leaves of pale green. It is native to South Africa where it grows among rocks and in the crevices of cliffsides and blooms from midsummer to fall. When grown in full sun, the edges can take on a rosy pink hue. It branches freely, growing up to 10.0″ tall in cultivation for a nice spilling effect in arrangements. Alternatively, it is easy to keep compact by pruning and replanting.

Soft succulents will not survive a hard frost, but if there is a risk of freezing temperatures they can be brought indoors to grow on a sunny window sill or under a grow light. They need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 50% to 70% mineral grit such as coarse sand, pumice, or perlite. Water deeply enough for water to run out the drainage hole, then wait for the soil to fully dry before watering again.

This variety is easy to re-root from stem cuttings. Look to our Succulent Cuttings Guide for tips on succulent propagation.

String Of Buttons Crassula: What Is A String Of Buttons Succulent

Stacked crassula plants, like the string of buttons, exhibit an unusual form as gray-green leaves spiral from the plant. Adding the string of buttons plant to your home increases interest in your collection or mixed succulent container.

What is a String of Buttons Plant?

Crassulaperforata, also known as string of buttons succulent, is a sprawling and shrubby plant that reaches 18 inches (46 cm.), beginning as an upright specimen. Later, this plant becomes prostrate due to height and weight. Short stacks of triangular leaves often turn pinkish red on the edges, making the plant stand out. Small, white,star-shaped flowers blossom on the well-placed and happy string of buttons. It is most attractive when it cascades from the sides of a pot.

The plant usually grows in colonies of three or more. When transplanting, keep the colony together for a full look. Some define them as “scrambling” in the sense of aggressive growth. You’ll love their multiplication, especially if you separate them for propagation.

Growing a String of Buttons Crassula

When growing a string of buttons, babies spring from the bottom of the plant. Divide and repot in spring, when possible. If you want to keep them upright, prune from the top and root the cuttings for more plants. You may also remove the babies with a sharp cut.

You can grow this great plant outside in the ground if you live where temperatures don’t dip below 50 degrees F. (10 C.), typically in USDA hardiness zones 9-12. This is the best opportunity for them to scramble, through your other succulents and flowers planted in the same bed. In other areas, you may put containers of them outside in morning sunlight in appropriate temperatures.

Care of a stacked crassula starts with planting it in appropriate soil, fast draining with amendments to ensure no water remains on the roots. Don’t water often. You’ll find most crassula, including this one, are often watered too frequently. If you can, collect rainwater for infrequent watering of this and other succulent plants.

Avoid hot afternoon sun in summer. Even crassulas, among the hardiest of these plants, don’t like too much heat and hot sun in high 80- to 90-degree F. (27-32 C.) range. When moving these plants outdoors in spring, acclimate gradually to full morning sun. Once you find the proper spot, leave them there until time to bring them inside in winter.

Succulents are usually not prone to insects and disease, but may sometimes be affected by mealybugs and fungal issues. Move the infected plant out of the sun before treating with 70 percent alcohol. More than one treatment is usually needed for this pest.

For minor fungal issues, sprinkle cinnamon on roots and in the soil. If this does not correct the problem, use an organic fungicide.

Crassula perforata (Necklace Vine) – This is a relatively fast growing “stacked” Crassula from South and Eastern Cape Province of South Africa north to Natal. It is a somewhat shrubby and sprawling plant to 18 inches tall with secondary branches rising nearly vertically bearing short broad ovate opposing leaves that are congested at the leaf tips and blooms with inconspicuous pale yellow flowers in spring. This form has leaf margins that often have reddish tinges and is quite showy. Plant in a well-drained soil in full coastal sun to light shade – needs some protection from midday heat in hot locales but the brighter light brings out the red tones and plants will flower more. Irrigate only occasionally to regularly. Hardy to around 20-25 F. This plant is called Necklace Vine because the leaves can be rotated around on the stem like beads on a string (this unfortunately to the detriment of the plant as this breaks the petiole, the leaf connection to the stem) or String of Buttons because the opposing pairs of lower cordate leaves appear threaded onto the stems and also Pagoda plant because of the regular arrangement of the leaves at the branch tip. The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery’s garden and in other gardens that we have observed it in. We also will incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing Crassula perforata.
