It may be hard to believe, but there was a time when I hated basil. I found it overly pungent, and it always seemed to overpower any dish. Thinking back on it, I might have been tasting bad quality basil — either basil that was past its prime or grown in stressed conditions. Today, I enjoy growing fresh basil and adding it to a myriad of dishes.

Think basil is just for making Italian foods like pasta and pizza? Think again. There are a wide variety of basil types, and all can be tools in your culinary kit. Here are 12 of my favorite basil varieties that I think you should consider growing in your garden — indoors or out.

Sweet Basil

Leigha Staffenhagen / Insteading

  • Sun requirements: Full sun. A sunny windowsill will do in most cases.
  • Moisture needs: Well-drained soil.
  • Best for: Nearly anything.

You may never have heard it referred to as sweet basil, but the stuff you buy in the grocery store is often this variety. It looks very similar to Genovese basil.

Thai Basil

  • Sun requirements: Full sun. Loves hot weather.
  • Moisture needs: Don’t overwater but avoid allowing the soil to dry out.
  • Best for: Cooking Thai dishes.

I’m growing a variety of Thai basil in my garden at the moment, and it seems to be one of the last to bolt. The slender leaves and purple flowers are a characteristic of Thai basil. So is the pungent, spicy flavor.

Purple Basil

  • Sun requirements: Full sun.
  • Moisture needs: Well-drained soil.
  • Best for: Adding color to dishes as an ingredient or garnish.

There are a few different kinds of purple basil out there, but they’re all somewhat similar in taste and texture.

What makes this type of basil stand out is its purple hue. Some varieties of purple basil are more pungent than others.

Lemon Basil

  • Sun requirements: At least six hours of sun.
  • Moisture needs: Water when topsoil is dry.
  • Best for: Adding a citrus-kick to basil-infused dishes.

This type of basil has a distinct lemon flavor. Of course, it still tastes like basil, but citrus undertones make this a truly unique basil to grow and add to dishes.

Holy Basil

  • Sun requirements: Full sun, thrives in the heat.
  • Moisture needs: Well-drained soil.
  • Best for: Medicinal treatment of headaches and stress.

This type of basil is native to India. It’s actually a perennial and has a host of medicinal properties.

  • Sun requirements: Heat-loving, needs full sun.
  • Moisture needs: Well-drained soil, but water well in the heat of the summer.
  • Best for: Cooking and garnishing traditional Italian dishes.

One of the most common types of basil, and one that I often grow in my garden, is Genovese basil.

Related Post: Everything Basil

This Italian variety pairs well with a variety of dishes and has smooth, bright green foliage.

Mammoth Basil

  • Sun requirements: Full sun.
  • Moisture needs: Well-drained soil.
  • Best for: Any dish where you might use sweet or Genovese basil.

This type of Italian basil produces very large basil leaves that look almost like lettuce leaf — which is why mammoth basil is sometimes also known as lettuce basil.

Cinnamon Basil

  • Sun requirements: At least six hours of sun per day.
  • Moisture needs: Well-drained soil.
  • Best for: Making a variety of sweet dishes.

My least favorite type of basil, but one that some people really enjoy, is cinnamon basil. I find it unpleasant, but perhaps that’s because I’m not a fan of actual cinnamon. It has its place in certain desserts but quickly overpowers a dish if used incorrectly. It’s sometimes called Mexican basil.

Licorice Basil

  • Sun requirements: Full sun.
  • Moisture needs: Well-drained soil.
  • Best for: Replacing anise in recipes and dishes when you’re out. Use it in desserts, or make teas with it.

This type of basil may be an acquired taste for some because of its strong anise flavor. If you don’t like licorice, find another basil variety to grow.

Greek Basil

  • Sun requirements: Full sun.
  • Moisture needs: Regular watering.
  • Best for: Garnishing dishes and growing in containers.

A compact variety that doesn’t get much taller than about 8 inches. The leaves are tiny, too. Pick a few small leaves to garnish or flavor dishes.

Dwarf Basil

  • Sun requirements: Needs a sunny spot.
  • Moisture needs: Moist but not waterlogged soil.
  • Best for: Garnishing dishes and drying. Grows well in containers.

I have a few different types of basil growing in my garden at the moment, but dwarf basil is one of my favorites. This year is the first time I tried growing a compact type basil, and I may never go back to regular varietals ever again. I love that it takes up little space and looks so attractive thanks to its tight cropped growing habit.

Tips For Growing Basil

Ever since I started out as a gardener, I grew basil. It’s one of the most popular herbs to grow because it’s used in so many dishes. However, growing basil isn’t always a cakewalk. The plant is finicky and particular about its living conditions.

Why put in the effort to grow basil, then? Because harvesting it from your homegrown plant is SO MUCH cheaper than buying bunches of fresh basil at the grocery store. Grow more than you need, and share it with others, or dry it for use during the winter.

Markus Spiske / Unsplash

In general, basil prefers sunny conditions. Never plant basil in an area where the soil is waterlogged. The soil should drain well and not puddle after heavy rainfall. Avoid growing basil in containers that are too small.

People tend to kill their basil plants because they keep them in store-bought containers that eventually suffocate the plant’s roots. Basil should be watered, but not too frequently. It’s better to let the soil dry out than keep it moist throughout the plant’s lifetime. Don’t bother fertilizing basil. Too much fertilizer can compromise the aroma and flavor of basil leaves.

Remember to pick your plant leaves frequently. This will encourage bushy growth and prevent the basil from flowering and going to seed.

How To Use Basil

If you find yourself in the fortunate position of having a ton of basil, check out these uses for the tasty herb.

Cooking

Obviously, the most popular way to use basil is to cook with it. Toss it into a pasta dish, add it atop pizza, or create a delicious fragrant pesto.

Gardening

The strong scent of basil can actually ward off pesky insects in the garden which is why basil is a frequently used companion plant for garden vegetables. Use basil as part of your natural bug spray recipe to help ward off troublesome pests.

Aromatherapy

Add a few drops of basil essential oil to water and create a fresh-smelling room spray. Add to bathwater for a soothing, anxiety-reducing bath. For some, the scent of basil helps to relieve headaches.

Medicinal Use

Basil has a few medicinal uses like aiding in digestion and reducing fatigue. For medicinal use, it’s often made into a tea for drinking. Basil also has antibacterial properties. Used topically, it can treat skin flare-ups like acne.

Basil plants are some of the easiest herbs to grow. Even better, there are many wonderful varieties to select from for use in various culinary dishes. With so many great options, choosing a variety can be a bit difficult. You may find around 40 different kinds at your local garden centers, or even more unique varieties you can grow from seed. Which to choose?! Read on to discover 18 beauties you might enjoy.

How to Care for Basil Plants

monicore /

Caring for basil plants is simple, no matter which variety you choose. It’s also the same whether you plant indoors or out.

These plants grow quickly when planted in well-draining, moist soil that has a neutral pH balance. Make sure the soil isn’t too wet, and water the plants from the base when the soil becomes dry to the touch. Make sure the environment remains warm (above 50 degrees F) and that they receive no less than six hours of full sunlight each day.

If you live in a hot location, your basil plants will benefit from afternoon shade.

Plant basil in the spring or summer, after there’s no chance of frost. If you live in a colder environment, you may consider protecting your basil plants. They’re very sensitive to frost. Each variety will require different spaces between the seedlings if you plant from seed as well, so make sure to pay attention to planting instructions based on the type you select.

You can also grow this herb indoors. Just note that potted basil needs 10 hours of fluorescent lighting each day, or to be placed in a sunny, south-facing window.

How Many Basil Plants Do I Need?

For a family of four, all you need is around two or three of your favorite basil plants. However, if you enjoy making sauces such as pesto from scratch, or freezing part of your harvest of year-round use, consider growing a dozen or more plants.

If you have a small yard, live in an apartment, or plan to grow an indoor herb garden, a smaller variety may work best for your needs. Tiny basil varieties are great for containers, and you can quickly move them outdoors during the hot summer months or indoors for protection during the freezing temperatures.

Some gardeners like to select one variety to plant, while others enjoy mixing a few different types of basil in a flower bed. Not only does this allow you versatility in the flavors you introduce to your meals, but various types of basil also appear great when paired together in an outdoor bed or container garden.

Basil Varieties

Potted Basil Plant

Now and again, I see people visiting Our Herb Garden who are looking for information on the different basil varieties available. I started out in the naive belief that I would need around half a day to put something together. Order, family, genus, species, cultivar – terms I hadn’t used since high school. How hard could it be to write about the different varieties of basil?

Oh, was I in for a rude awakening.

Species, variety and cultivar appear to be used with reckless abandon even by folks who should know better. It seems there are somewhere around 33 species of basil and as many as 200 varieties or cultivars of basil. There are annuals, perennials and shrubs. There are sweet basil varieties, spicy, fruity and licorice flavored varieties of basil. The leaves can be tiny or as big as lettuce leaves. The flowers range from bright white to purples that are almost black. Basil plants can have green leaves, purple leaves and even red leaves.

Basil apparently cross-pollinates easily – one scientific paper referred to it as “promiscuous.” Some of the species and cultivar names are being used interchangeably and I suspect more than a few sites are providing inaccurate information. Even scholarly sources seem to contradict themselves. And, just in case there wasn’t enough confusion, some portions of the genus have been reclassified in recent years.

I thought I would start at the beginning.

Let’s get the really easy one out of the way, we are talking about living organisms from the Kingdom of Plantae – i.e., plants.

Basils are in the order Lamiales – flowering plants, whose first leaves or seed leaves grow as a pair (known by the scientific term dicotyledons). Other well-known garden plants in this order include jasmine, lavender, lilac, mint, olive, rosemary and snapdragon.

Lamiaceae or Labiatae is the mint or deadnettle family of plants. This group includes basil, hyssop, lavender, marjoram, mint, oregano, sage, thyme and rosemary.

Now we are to the basils – genus Ocimum.

There’s a shorthand and method to how cultivars are named. The best article I found that explains how it all works together is on the Floridata website. The naming of species is a bit of first come, first named for. When a name is accepted but later considered to be what amounts to a duplicate, it is reclassified as a synonym. But, unlike the words ‘pretty’ and ‘lovely’ the two scientific names are not interchangeable. The accepted name is the only one that should be used.

When discussing the various species, scientists will often abbreviate the genus name with the first letter. Ocimum basilicum becomes O. basilicum.

I was able to find information on 11 of the basil species. In time, this page will link to more detailed information about a selection of basil cultivars and where you can buy seeds and plants.

americanum

Ocimum americanum is also known as American, lemon basil, wild basil and “hoary” basil. The origins of this species of basil are tropical Africa and Asia. They generally grow 1-3 feet tall and are somewhat bushy. One historic work described the growth habit as looking like a broom. This species tends to prefer sunny, wind-sheltered conditions. Small leaves grow in pairs with larger separations along the stem than some of the other basil varieties. The leaves have an intense lemon scent. Flowers are typically white to whitish lilac.

Cultivars include lime basil.

It seems these tender perennials which require protection in colder climates.

basilicum

Basil Leaves

Ocimum basilicum is the species of basil that is most commonly used in cooking. It is also called sweet basil, common basil and sometimes Thai basil. Most commercially sold cultivars are sweet basil.

O. basilicum generally blooms from June to frost. The flowers are described as magenta. These annual herbs like full sun and well-drained soil with regular watering.

Cultivars include: lime basil, boxwood, horapha (anise basil), napolatano, genovese, lettuce leaf, nufar, purple ruffles, queen of sheba, sweet dani, sweet large leaf Italian, Thai Siam queen and Well-sweep miniature purple. At least one site recommended Sweet Genoese/Genovese Profumitissima as being the the variety with the truest basil flavor.

campechianum

Ocimum campechianum is not actually a basil, as we know them, despite being listed in the Ocimum genus. (I did mention all of this is confusing, right?) This Amazon native has essential oils that are comparable to the essential oils of common basil and thyme. It is also known as Amazonian basil, wild sweet basil, wild mosquito plant, least basil, Peruvian basil, spice basil, alfavaca-do-campo, manjericao and estoraque.

Plants generally grow only up to 18 inches tall. Flowers are pinkish-lavender or white. It has naturalized in South America and the southernmost portions of Florida. (It is considered endangered in Florida.)

Some cultures use O. campechianum as a cooling tea or mosquito deterrent but it not generally considered a true culinary herb, though some cultures use it to flavor soups and stews. It is used in Central American folk medicine for colds, stomach disturbances, parasitic infestations and dysentery.

canum

Also known as camphor, hoary or hairy basil. A sweetly-scented, perennial basil from Asia. Generally smaller plants that grow 6 to 24 inches tall with leaves ½ -1 ½ inches long. The flowers are white. The few references I found to this species were from the 1800s. It does, however, seem to be actively grown in India for its medicinal properties.

citriodorum & x citriodorum

These terms are being used interchangeably to refer to the same group of basil varieties. Since Our Herb Garden is about home gardening and not a scientific journal, I’m just going to assume they are one and the same and not actually two different things. I suspect ‘x citiodorum’ is the correct version and folks just drop the ‘x’.

This species is actually a hybrid between O. basilicum (common basil) and O. americicanum (African basil). It can also be referred to as lemon basil, Thai lemon basil or Lao basil. While this type of basil is a mainstay in Laos and Indonesia, it is somewhat new to American kitchens.

Both the seeds and the leaves are treasured for their lemon-flavor. The seeds are soaked in water and often used in sweet desserts. This species flowers from June to October. Plants grow to around 18 inches tall and 12 inches wide. They like full sun to dappled shade but will not grow if in an overly shady spot.

One of the more popular cultivars of O. citriodorum appears to be “Perpetual Pesto.”

fruticulosum

Generally grows 8-12 inches tall, branching from a woody base. Appears to be a native of the African continent.

gratissimum

Ocimum gratissimum is a species of basil that is also sometimes known as African basil (yes, O. americicanum is also often called African basil), African curry, clove basil, tree basil and wild basil (in Hawaii). As the name implies, this species is a herbaceous perennial grass. It is woody at its base with fuzzy, lime-green leaves. It likes wet conditions and is often found along roadsides. It is considered an invasive species in some parts of the world, particularly in New Caledonia and the Cook Islands.

In Nigeria, many eat the leaves as a vegetable.

kilmandscharicum

Also known as hoary basil but unlike O. canum this one is from Africa. One popular cultivar is African Blue. The flavor is quite strong and camphorous. Recipes from Africa will often require this type of basil to obtain an authentic flavor. They are tender perennials. Their longer-growing nature makes them ideal to be crossed with sweeter basils to take advantage of the perennial nature of one while obtaining the sweeter flavor of the other.

Sachets made from the camphor-scented leaves are often used to protect woolens. The leaves are also made into a tea as a treatment for upset stomach.

minimum

A dwarf bush species used much like sweet basil. Can be grown in containers. Native of Ceylon.

obovatum

This species is also known as Greek basil. It’s fine leaves and pungent aroma make it a favorite for commercial growers offering dried basil leaves. The relatively compact size makes it a good choice for containers.

A number of seed companies are referring to Greek basil as O. basilicum minimum but my research indicated that may be an incorrect classification.

tenuiflorum

The species ocimum tenuiflorum is similar to common basil (O. basilicum) but is considered a short-lived perennial and has smaller flowers. It can grow up to 3 feet tall. They are “hairy” and often purplish with pale purple flowers. In Asia, it is often known as clove basil, holy basil, tulsi and tulasi. It is spiritually important in Hinduism and was often grown in large vessels near the entrances to Hindu forts and temples. They also use the wood of the plants to make beads for their rosaries.

Here’s where the naming stuff goes awry again. Some sites are listing Ocimum sanctum as a synonym of O. tenuiflorum and others are listing O. tenuiflorum as the synonym of O. sanctum and others are using both separately. I’m guessing references to holy ___ or sacred ____ cultivars are all of the species O. tenuiflorum.

On Researching the Many Basil Varieties

It was easier to find lists of language translations of the different species than information on the plants themselves. Older sources used highly scientific descriptions that us mere mortals would never hope to understand. Plant origins seemed to matter more than growing habits and physical characteristics.

Two scientists compared 37 different cultivars of basil, primarily O. basilicum. While not the goal of their research, it certainly showed that basil varieties, even in the same species vary greatly. Flowers took 16 to 64 days to bloom. The quickest bloomers were Blue Spice and Sweet Dani; the slowest Fino Verde, Magical Michael and Purple Ruffles. Fino Verde produced the highest fresh weight and dry weight yields (could slower to flower varieties mean more tasty leaves to harvest?). Heights varied too – Spicy Bush was the smallest and Sweet Dani was the tallest.

The differences in basil species appear to be determined at the chemical level. Leaf size, color, scent and taste do not always provide reliable clues to identification. But, in the end, does it matter what each basil species or basil variety is called? What matters is if it will grow in Our Herb Garden and provide the basil taste we hunger for.

Cinnamon Basil Vs. Thai Basil: SPICEography Showdown

Cinnamon and Thai basil both belong to the same family that includes regular basil (AKA sweet basil or Mediterranean basil) and mint. One factor that can make a comparison between these two tricky is that some people refer to cinnamon basil as Thai basil. Both cinnamon basil and Thai basil are common ingredients in Thai cooking. The Thai basil that most people from the West know is a separate plant that is also called horapha. These two herbs clearly have a lot in common but there are also some major differences that we will cover in the SPICEography Showdown below.

How does cinnamon basil differ from Thai basil?

As its name suggests, cinnamon basil gives a cinnamon-like flavor to your food in addition to some of the notes that you would expect from basil. The cinnamon flavor comes from a compound called methyl cinnamate.

In comparison, the flavor that Thai basil brings to food is closer to the anise or licorice flavor than it is to that of cinnamon. Thai basil also has an intense camphor note. You should note that cinnamon basil is just one of multiple herbs that are sometimes called Thai basil. Holy Thai basil is also known as kra phao is among them.

Cinnamon basil does not handle being cooked very well. Its flavor profile is not as robust as that of Thai basil, which is basically made for high-heat dishes. Thai basil’s flavor profile blooms in Southeast Asian wok-preparations.

Can you use cinnamon basil in place of Thai basil and vice versa?

Cinnamon basil can work as a substitute for Thai basil. Since Thai cooks use both, neither herb has a flavor profile that will seem out of place in a Thai dish. Both are pungent, which means that either will work if all you want is an intensely aromatic herb with a basil note. The two herbs are also nutritionally similar.

That said, cinnamon basil and Thai basil will not give you exactly the same flavor profile. Both the Holy Thai basil and horapha varieties of Thai basil deliver a spicy intensity that verges on being peppery. That intensity (as well as the strong camphor note) are among the characteristics that set them apart from cinnamon basil. If you are trying to get a flavor similar to that of Thai basil, there are better options than cinnamon basil even though cinnamon basil is not a bad substitute.

When should I use cinnamon basil and when should I use Thai basil?

Aside from its use in Thai cooking, you can use cinnamon basil in sweet dishes where it can stand in for sweet basil and for cinnamon. Use it in seasonal fall dishes that feature squash or pumpkin. You can use it in place of mint as well. Alternatively, you can use cinnamon basil to give traditional basil dishes a new flavor twist. Like sweet basil, cinnamon basil goes well with tomatoes. It is a particularly good partner for stewed tomatoes and other forms of cooked tomatoes. Cinnamon basil is also great a tea herb.

Use Thai basil in Thai stir-fried dishes and other cooked applications since its flavor does not fade as quickly when compared to other basil varieties. It stands out in salads where it can provide a flavor profile that is zestier and brighter when you compare it to that of regular sweet basil.

It seems so many people can’t differentiate these two kinds of herbs, Holy Thai Basil (Krapow) and Sweet Thai Basil (Horapa). Besides, many restaurants also use the wrong type of basil in their cooking. Baan Ying Singapore with the vision of serving great Thai taste and flavours would seek to share the world of the two commonly used basils in Thai cuisine.

Holy Thai Basil (Krapow) and Sweet Thai Basil (Horapa) are members of the mint family. There are more than 40 basil variations, including lemon, cinnamon and Thai basil. Basil plants can be grown in a home garden.

Since their appearance is very similar, they are actually different in many ways. The leaves of Holy Thai Basil (Krapow) are grey-green in color, coarse to the touch, and have rigged edges. While the Sweet Thai Basil (Horapa) leaves are deep green and tend to be smooth with smooth edges.

Holy Thai Basil (Krapow) has a spicy aroma, and Sweet Thai Basil (Horapa) has a sweet fragrance. Holy Thai Basil and Sweet Thai Basil tend to have sharp flavors when raw, which is similar to other varieties of greens. Holy Thai basil (Krapow) varieties all have strong flavor and aroma, and leaves will bruise and emit scent easily.

Both Holy Thai Basil (Krapow) and Sweet Thai Basil (Horapa) contain large of the benefits. The majority of the great benefits of Holy Thai Basil (Krapow) can be attributed to its volatile oils and flavonoids – powerful, plant-based antioxidants that reduce inflammation, help fight aging, and promote healthy arteries whereas Sweet Thai Basil (Horapa) helps your body adapt to stress and promotes mental balance. Sweet Thai Basil (Horapa) also provides vitamin A and C, calcium, zinc, iron, chlorophyll.

Holy Thai Basil (Krapow) and Sweet Thai Basil (Horapa) can be cooked or served raw in similar styles. Grind up raw basil in a food processor with pine nuts, garlic and olive oil to make homemade pesto sauce for pasta. Add torn leaves to a soup, stir fry or casserole to add a strong fragrance and fresh, herbal flavor.

Baan Ying Singapore proudly serves dishes with those two authentic ingredients, Holy Thai Basil (Krapow) and Sweet Thai Basil (Horapa), in the sense of real Thai dishes, and these are some recommendations:

  • Holy Thai Basil (Krapow) Menu

1. Thai Basil Stir-fired Chicken/Pork (Pad Krapow Gai/Moo)

2. Tender Pork Rib in Spicy Broth ( Tom Zap Kra Dook Moo)

  • Sweet Thai Basil (Horapa) menu

1. Green Curry with Chicken (Gang Kiew Wan Gai)

2.. Stir-fried Eggplant With Minced Pork, Garlic and Chili (Pad Ma Kue Yao)

3. Spicy Clams Stir-fried With Chili Paste (Hoi Lai Pad Prik Pao)

Western sweet basil: Also dubbed Mediterranean basil for its popularity across that region. It is most famously used in Italian pesto and as a frequent sidekick for tomatoes and olive oil in various dishes. Many cultivars with different leaf sizes and shapes exist. Shown here is the type most commonly sold here, with fleshy stems and soft, slightly cup-shaped green leaves that can reach 10 to 12cm in length. It has a sweet, almost floral aroma with distinct clove notes. Its aroma changes and is attenuated in the dried herb, becoming more hay-like and less sweet. Fresh sweet basil can be blended into a paste with some oil and frozen in an airtight container for storage.

Thai sweet basil: Called bai horapa in Thai, this has purple stems, green leaves and dark purple flower spikes. It has strong anise and liquorice notes and, when cooked, is more spicy and forward than Western sweet basil. Add to stir-fries, curries, soups and stews right at the end of cooking. It releases its fragrance as it wilts in the heat. In Thailand, it is also eaten raw as part of a vegetable platter served with nam prik relishes. In Taiwan and China, a basil cultivar with a similar aroma profile is used in recipes such as san bei ji (three cup chicken) and also in Hakka dishes such as lei cha, pestle-pounded mixed herb tea.

Holy basil: Called bai krapao in Thai, this is sharp and peppery – hot to the taste when very fresh. Its piercing aroma, which intensifies when the herb is heated or very lightly cooked, has subtle camphor and allspice notes. Thai groceries may sell two types. The purple type (above) has dark purple stems and purple-flushed green leaves and is a bit stronger in character. It is a good partner for meats and chilli-hot dishes. The “white” type (below) has green leaves on pale green and pale purple stems, and its slightly milder nature suits white meats and seafood. Called tulsi in Hindi, holy basil has few if any culinary applications in India, but is used for devotional purposes and in traditional Ayurvedic medicine.

Lemon basil: Shown here are two types. One is a Western variety (above) with wide, pale green leaves and zesty lemon accents layered atop sweet basil’s clove scent. The other is Thai lemon basil (below), called bai maenglak in Thailand and daun kemangi in Malaysia and Indonesia. It has slightly slimmer and darker green leaves, soft and faintly fuzzy stems, and a gentle but pervasive scent hinting at lemongrass, lemon and lime. Both kinds complement seafood, mild curries and soups very well and should be very lightly cooked, if at all.

Cinnamon basil: Bearing serrated-edged green leaves on reddish-purple-tinged stems, this plant has a heady cinnamon character besides a sweet basil aroma profile. Its unique fragrance makes it amenable to savoury dishes, such as stews, braises, soups and salads, as well as sweet dishes, such as fruit compotes and salads, ice cream and sauces. Try it in fruity beverages such as sangria or a Pimms Cup.

Purple basil: Several cultivars exist around the world, differing in leaf shapes and shades. Shown here is one with serrated-edged, teardrop-shaped leaves with a purple-green top and grape-purple underside. Purple basil has an assertive sweet basil aroma. Infuse it in white vinegar to obtain a fragrant, purple-tinted condiment.

Storing basil: Lemon basil and holy basil are fragile and wilt soon after picking, especially in warm conditions, so use them as soon as possible. Swaddle the other types in paper towels, place in plastic bags, gently press out all the air, seal and store in the fridge vegetable drawer for a couple of days. Supermarket potted basil will last for several days if kept well watered, but re-pot it with more compost to keep it going for longer.

Basils: Plant Care and Collection of Varieties

If you do any Italian cooking at all, you’ll want to include basil in the herb garden. Basil can’t be planted until after the last frost date, but in the heat of summer it will produce abundantly.

About basils
There are several types of basil to choose from. The most common is bush or sweet basil, a compact plant growing to 18 inches or so during the season. Purple basil adds a splendid burgundy color to the garden. It can be used like common basil, though it’s a little less sweet. The purple leaves create a beautiful color when steeped in white vinegar. Recently rediscovered by many cooks, lemon basil adds a lemony basil fragrance to both the garden and the kitchen. Thai basil adds a licorice flavor and tastes great in Asian cooking. Basil is a heat-loving annual herb.

Choosing a site to grow basils
Plant in full sun in moist, well-drained soil.

Planting Instructions
Start seeds indoors six weeks before the last frost date or seed directly in the garden (about 1/4 inch deep) after the last frost date when soil is warm. Set transplants or thin seedlings to stand at least 10 to 12 inches apart; more room (16 to 24 inches apart) will encourage low, bushy plants to develop.

Ongoing Care
Pinch off the center shoot of the basil plant after it has grown for 6 weeks to force side growth and prevent early flowering. If flower stalks do develop, cut them off. Mulch is recommended in hot areas since basil likes a steady moisture supply. Basil is generally pest-free. Early cold weather can ruin a maturing crop, so be sure to harvest if temperatures are expected to dip below 40 degrees F.

How to harvest basils
Basil is at its most pungent when fresh. The best time to harvest is just as the plant starts to bud, well before flowers bloom. Snip leaves or branches at this time and pinch off flower buds to keep the plant productive. You also can cut the entire plant about 6 to 8 inches above ground, leaving at least one node with two young shoots intact. The plant should produce a second but smaller harvest several weeks later.
Since the leaves lose some of their flavor when dried, freezing is the best method for winter storage. To quick-freeze basil, dry whole sprigs and pack them in plastic bags with the air pressed out. To dry basil, pinch off the leaves at the stem and dry them in a shady, well-ventilated area. Check in 3 or 4 days, and if they are not totally dry, finish drying in the oven, otherwise the leaves may turn brown or black. Use the lowest heat possible with the door slightly open, turn leaves for even drying, and check frequently.
