What are Kinds of Basil Plants and Why They Are Important in Gardening
“Kinds of basil plants” refers to the distinct cultivars, or cultivated varieties, of the Ocimum basilicum species, commonly known as sweet basil. While they all share the fundamental characteristics of the basil family – aromatic leaves, a preference for warm weather, and a generally bushy growth habit – they diverge significantly in their sensory attributes and physical appearances.
The importance of understanding these different kinds of basil plants stems from their impact on:
Culinary Versatility: Different basil varieties possess unique flavor profiles. Some are sweet and mild, perfect for fresh salads and classic Italian dishes, while others are peppery, anise-scented, or even carry notes of lemon or cinnamon. Choosing the right basil can transform a simple meal into a gourmet experience.
Garden Aesthetics: Beyond their edible qualities, many basil varieties boast striking foliage colors, from deep purple and bronze to variegated patterns and ruffled textures. This makes them not only a culinary staple but also an attractive ornamental plant in borders, containers, and herb gardens.
Pest and Disease Resistance: Certain basil cultivars may exhibit greater resilience to common garden pests and diseases, making them easier to grow and more productive. Understanding these differences can lead to a healthier and more sustainable herb garden.
Pollinator Attraction: Like many aromatic herbs, basil flowers are highly attractive to bees, butterflies, and other beneficial pollinators. Different varieties might attract slightly different insect populations, contributing to overall garden biodiversity.

Detailed Breakdown of Kinds of Basil Plants
The world of basil is vast and fascinating, with hundreds of cultivars documented. While Ocimum basilicum is the most common species for culinary use, other related Ocimum species also offer unique flavors. We’ll focus primarily on the diverse varieties within Ocimum basilicum for this exploration.
The Classic: Genovese Basil (Ocimum basilicum ‘Genovese’)
What it is: This is perhaps the most iconic basil variety, renowned as the quintessential ingredient for authentic Italian pesto. Its large, bright green leaves are slightly crinkled and possess a classic sweet, slightly peppery, and aromatic flavor with hints of clove.Why it matters: Genovese basil is the benchmark for basil flavor for many. Its robust aroma and taste hold up well in cooked dishes, but it truly shines when used fresh. It’s a reliable grower for most gardeners in suitable climates.
Botanical Perspective: Ocimum basilicum is an annual herb in cooler climates, originating from tropical regions of central Africa and Southeast Asia. It belongs to the Lamiaceae family, which also includes mint, rosemary, and thyme, explaining its aromatic oils. ‘Genovese’ is a cultivar selected and propagated for its specific desirable traits.
Practical Applications: Beyond pesto, Genovese basil is fantastic in tomato sauces, caprese salads, pizzas, pasta dishes, and as a fresh garnish. Its leaves can be dried, though the flavor is significantly reduced compared to fresh.
Common Myths: A common misconception is that all basil tastes the same. Genovese basil has a distinct flavor profile that differs from, say, Thai or lemon basil.
Expert Tips: For the most intense flavor, harvest basil leaves in the morning after the dew has dried but before the heat of the day. Gently pinch off leaves rather than tearing them.
Seasonal Considerations: Genovese basil thrives in warm, sunny conditions. It’s highly sensitive to frost and will quickly perish if exposed to cold temperatures. In regions with short summers, starting seeds indoors 6-8 weeks before the last frost is recommended.
The Aromatic All-Rounder: Sweet Basil (Ocimum basilicum)
What it is: Often used interchangeably with Genovese, “Sweet Basil” can also refer to the broader category of basils with a classic sweet, aromatic flavor profile, without the specific characteristics of a named cultivar like ‘Genovese’. However, many seed packets simply labeled “Sweet Basil” will indeed be varieties very similar to Genovese.
Why it matters: This is the go-to basil for general culinary use, offering a pleasant, familiar aroma and taste that complements a wide range of dishes. It’s a forgiving plant for beginners.
Practical Applications: Use it in salads, sandwiches, pasta, and as a versatile fresh herb garnish. It’s also a popular choice for growing in pots on windowsills.
Common Mistakes to Avoid: Planting sweet basil too early in the season before all danger of frost has passed. Basil needs warmth to thrive.
Expert Tips: To encourage branching and more leaf production, pinch out the growing tips of young plants just above a set of leaves.
The Exotic Spice: Thai Basil (Ocimum basilicum var. thyrsiflora)
What it is: Easily recognizable by its purple stems, serrated green leaves, and a distinct anise or licorice-like aroma with a peppery finish. Thai basil has a more robust and slightly spicy flavor than sweet basil.
Why it matters: It’s indispensable for authentic Southeast Asian cuisine, particularly Vietnamese pho, Thai curries, and stir-fries. Its unique flavor profile adds complexity and fragrance that cannot be replicated by other basil varieties.
Botanical Perspective: While often categorized under Ocimum basilicum, some botanists consider Thai basil a distinct variety or even a separate species (Ocimum thyrsiflora). Its characteristic scent comes from compounds like estragole and methyl chavicol, which are present in other basils but in different ratios, giving Thai basil its unique aroma.
Practical Applications: Add it fresh to noodle dishes, curries, soups, and spring rolls. It’s also surprisingly good in cocktails and desserts where its anise notes can shine.
Common Mistakes to Avoid: Overcooking Thai basil. Its delicate flavors are best preserved by adding it at the end of cooking or using it raw.
Expert Tips: Thai basil plants tend to grow more upright and can get quite tall. Providing support may be necessary as they mature, especially in windy conditions.
The Fiery Scent: Holy Basil or Tulsi (Ocimum tenuiflorum, formerly Ocimum sanctum)
What it is: Revered in India for its religious significance and medicinal properties, Holy Basil (Tulsi) has a complex flavor profile that can range from peppery and clove-like to minty and slightly astringent. It typically has fuzzy, green or purple leaves and a more compact, shrubby growth habit.Why it matters: Beyond its culinary uses, Holy Basil is a staple in Ayurvedic medicine, often consumed as a tea for its purported health benefits. Its unique flavor can add an exotic touch to dishes.
Botanical Perspective: This species is distinct from Ocimum basilicum. Its medicinal properties are attributed to its rich essential oil content, including eugenol, which is also found in cloves.
Practical Applications: Used to make Tulsi tea, it can also be added to stir-fries, curries, or used as a unique flavoring agent in beverages.
Common Mistakes to Avoid: Confusing Holy Basil with sweet basil. While both are basil, their flavor profiles and uses are quite different.
Expert Tips: Holy Basil plants are often grown as ornamentals as well, especially the purple-leafed varieties, due to their attractive form and fragrant foliage.
The Cinnamon Kiss: Cinnamon Basil (Ocimum basilicum ‘Cinnamon’)
What it is: This variety boasts a warm, sweet aroma and flavor that distinctly hints at cinnamon, along with a slightly peppery undertone. Its leaves are typically smaller and glossier than Genovese basil.Why it matters: Cinnamon basil offers a delightful departure from classic basil flavors, opening up new possibilities in both sweet and savory cooking. It’s perfect for adding a unique twist to baked goods, fruit salads, and spiced dishes.
Practical Applications: Excellent in fruit salads, baked apples, cookies, and as a complement to chocolate. It also pairs well with poultry, pork, and in savory sauces.
Common Mistakes to Avoid: Expecting it to taste exactly like cinnamon sticks. It has a basil base with cinnamon notes, not a pure cinnamon flavor.
Expert Tips: Try infusing milk or cream with cinnamon basil for a fragrant base for custards or ice cream.
The Citrus Zing: Lemon Basil (Ocimum basilicum ‘Lemon’)
What it is: As the name suggests, this basil variety offers a bright, lemony aroma and flavor that is less pungent than sweet basil, making it a refreshing addition to many dishes. It typically has smaller leaves.
Why it matters: Lemon basil provides a delicate citrus note that complements seafood, chicken, vegetables, and light pasta dishes without overpowering them. It’s also a fantastic addition to salad dressings and marinades.
Practical Applications: Ideal for use with fish, poultry, vegetables (especially green beans and tomatoes), in salad dressings, marinades, and even in herbal teas.
Common Mistakes to Avoid: Using too much, which can sometimes result in a slightly bitter or soapy taste if over-harvested or overcooked.
Expert Tips: Lemon basil is a stellar companion for grilled or roasted vegetables. Toss them with olive oil, lemon basil, and a pinch of salt and pepper just before serving.
The Deep Hue: Purple Basil Varieties (e.g., ‘Dark Opal’, ‘Purple Ruffles’, ‘Osmin’)
What they are: These cultivars are prized for their stunning foliage, which ranges from deep emerald green with purple undertones to rich burgundy and violet. ‘Dark Opal’ offers a classic basil flavor with a slightly more intense, peppery note, while ‘Purple Ruffles’ has frilly, ruffled leaves with a milder, sweet flavor. ‘Osmin’ is an award-winning purple basil with a strong, classic basil aroma.Why they matter: Purple basil varieties add incredible visual appeal to both the garden and the plate. Their deep colors make them stand out in salads, garnishes, and mixed herb bouquets. While their flavor can vary, they generally offer a satisfying basil taste.
Botanical Perspective: The purple coloration in these basil varieties is due to anthocyanins, the same pigments that give blueberries and red cabbage their colors. These compounds are antioxidants.
Practical Applications: Use them in salads, as a garnish for antipasto platters, in pesto (which will turn a beautiful pinkish-purple), and in any dish where visual appeal is as important as flavor.
Common Mistakes to Avoid: Expecting all purple basils to taste identical. Flavor profiles can vary, so it’s worth trying a few.
Expert Tips: The vibrant color of purple basil can sometimes fade slightly when cooked. For maximum visual impact, use them fresh or add them at the very end of cooking.
The Compact Growers: Bush Basil (‘Spicy Globe’, ‘Dwarf Greek’)
What they are: These are compact, often spherical, basil plants that grow to only about 10-12 inches tall and wide. ‘Spicy Globe’ is known for its small, fragrant leaves and a slightly spicy, sweet flavor. ‘Dwarf Greek’ is similarly compact with tiny, aromatic leaves.Why they matter: Bush basil varieties are perfect for container gardening, window boxes, and small spaces. Their tidy growth habit makes them easy to manage and harvest.
Practical Applications: Ideal for growing on windowsills, balconies, or patios. Their small leaves are great for garnishing drinks, small appetizers, or for use in micro-herb salads.
Common Mistakes to Avoid: Overcrowding them in pots. While compact, they still need adequate space for air circulation.
Expert Tips: Pinching the tips of bush basil plants regularly will encourage even more dense growth, making them look like perfect little green pom-poms.
The Unique Notes: Other Interesting Basil Varieties
Anise Basil (Ocimum basilicum ‘Anise’): Offers a distinct licorice-like aroma and flavor, similar to Thai basil but often more pronounced. Great in fruit salads and with seafood.
Lime Basil (Ocimum americanum, formerly Ocimum basilicum ‘Lime’): A hybrid with a strong lime scent and flavor. Perfect for fish, poultry, and in cocktails or desserts.
African Blue Basil (Ocimum kilimandscharicum x basilicum ‘African Blue’): A large, vigorous hybrid with a camphoraceous scent and hints of mint and basil. Its large, attractive purple-tinged leaves make it a beautiful ornamental, and it’s quite heat-tolerant.
Siam Queen Basil: A popular Thai basil cultivar known for its uniform growth, upright habit, and excellent anise-basil flavor. Often used in culinary competitions and by chefs.
Practical Applications in the Garden
Understanding the different kinds of basil plants allows for strategic planting and more rewarding harvests:
Culinary Planning: If you frequently make pesto, Genovese is your champion. For authentic Pad Thai, you need Thai basil. For an exotic tea, grow Holy Basil.
Container Gardening: Compact varieties like ‘Spicy Globe’ or ‘Dwarf Greek’ are perfect for pots on balconies or windowsills. Even larger varieties can be grown in containers if given adequate space and sun.
Companion Planting: Basil is known to deter some pests, like flies and mosquitoes, making it a good companion for tomatoes, peppers, and cabbage. Its aromatic nature can also attract beneficial insects.
Attracting Pollinators: All basil varieties, when allowed to flower (though not recommended for maximum leaf production), will attract bees and butterflies with their nectar-rich blooms.
Aesthetic Appeal: Incorporate purple basil varieties into flower beds or mixed borders for a splash of color and texture.
Common Mistakes to Avoid
Overcrowding: Basil plants need good air circulation to prevent fungal diseases. Space them appropriately based on their mature size.
Underwatering: Basil loves consistent moisture, especially in hot weather. Allowing plants to completely dry out can stress them, leading to wilting and reduced flavor.
Overwatering: Conversely, waterlogged soil can lead to root rot. Ensure your soil drains well.
Planting Too Early: Basil is a heat-loving plant. Planting outdoors before the last frost or when temperatures consistently drop below 50°F (10°C) will shock or kill the plants.
Not Harvesting Regularly: Letting basil plants go to seed prematurely (bolting) before you’ve had a chance to harvest significantly reduces leaf production and can alter flavor. Pinching back the growing tips and harvesting regularly encourages bushier growth.
Using Only One Variety: Missing out on the diverse flavors and aromas of different basil kinds is a culinary and gardening loss. Experiment!
Expert Tips or Pro Insights
Succession Planting: To ensure a continuous harvest of fresh basil throughout the growing season, sow seeds or plant seedlings every 2-3 weeks. This is especially important for annual varieties that might bolt in heat.Hydroponics and Aquaponics: Basil, particularly varieties like Genovese and Thai basil, thrives in hydroponic and aquaponic systems due to its need for consistent moisture and nutrients.
Cuttings for Propagation: Basil roots easily from cuttings. If you have a favorite variety, take cuttings from healthy plants, remove lower leaves, and place them in water. Once roots develop (usually within a week or two), plant them in soil. This is a great way to perpetuate a specific cultivar or to quickly start new plants.
Soil pH: Basil prefers slightly acidic to neutral soil, with a pH range of 6.0-7.0.
Fertilizing: While basil doesn’t require heavy feeding, a balanced liquid fertilizer applied every 4-6 weeks can boost growth, especially for plants in containers.
Seasonal or Climate Considerations
* Spring: Start basil seeds indoors 6-8 weeks before the last expected frost.
