Lime Basil
Lemon Basil
Lime basil brings the bright, zesty spirit of tropical Africa and South Asia straight into your garden, with a flavor profile that's part citrus, part peppery warmth, and entirely distinctive. This heirloom annual grows to 18-20 inches tall with small, smooth, bright green leaves that often display slightly scalloped edges, reaching harvest in just 60-69 days. Hardy in zones 4-11, it thrives in full sun and grows equally well in containers, raised beds, or garden plots. What makes lime basil truly special is its dual identity: equally at home in the kitchen or a pollinator garden, where its fragrant foliage draws bees and butterflies while delivering an unexpected citrus note to any dish.

Highlights
The small, velvety leaves carry a distinctly lemony scent that sets them apart from common basil at first touch. Lime basil's hairy stems and smaller, more delicate foliage give it a refined appearance, while the flavor combines sweet basil's approachability with a sharp, refreshing lime-and-pepper character. Pollinators adore it, and a single sprig tucked into a floral arrangement or drink releases a remarkable burst of scent that lingers long after the leaf is gone. This is the basil that transforms Thai dishes, cries out for seafood, and turns a simple tea or cocktail into something unforgettable.
Common Uses
Lime basil shines wherever bright, citrusy freshness is needed. Use it fresh in salads, seafood dishes, and salsas, where its small leaves pack outsized flavor without overwhelming delicate proteins. It's an exceptional tea herb, either steeped alone for a gentle lime-scented infusion or blended with other herbs for complexity. Cooks prize it for making infused simple syrups that transform cocktails and non-alcoholic beverages into restaurant-quality drinks, and it's fundamental to many Southeast Asian curry pastes and fresh herb preparations. A few sprigs tucked into a floral arrangement perfume an entire room with their zesty fragrance.

Care Instructions
Start Indoors
Start seeds indoors 6-8 weeks before your last spring frost in a warm location. Keep soil consistently moist and maintain temperatures around 70-75°F for reliable germination. Transplant seedlings into individual containers once they've developed two true leaves.
Transplant Outdoors
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before transplanting. Move plants to their final location after the last frost date has passed and soil temperatures consistently reach 70°F. Space plants 12 inches apart, with 18 inches between rows if planting multiple rows. Lime basil is container-friendly, thriving in pots at least 6-8 inches in diameter filled with rich, well-draining potting mix.
Direct Sow
You can direct sow seeds outdoors after the last frost date when soil temperature reaches 70°F. Sow seeds 1/4 inch deep in moist soil and keep the area consistently moist until seedlings emerge in 7-10 days.
Harvesting
Begin harvesting fresh leaves once the plant reaches 6-8 inches tall, typically 60-69 days from planting. Harvest in the early morning after dew has dried but before the heat of the day, when the leaves are most flavorful and aromatic. Pinch or snip the top 1/4 inch of stems and leaves, harvesting from multiple growth points to keep the plant productive throughout the season. Continue harvesting regularly to prevent flowering and extend your harvest well into the growing season. The smallest leaves are the most tender and aromatic, making them ideal for fresh use in drinks and delicate preparations.
Pruning
Pinch off the top growing tips and flower buds regularly to encourage bushier, more compact growth and delay flowering. This frequent harvesting actually improves the plant's productivity, as lime basil responds to pinching by branching more prolifically. Remove any lower leaves that yellow or show signs of damage to direct energy toward healthy foliage.

History & Origin
“Lime basil's story spans continents and centuries, beginning in the tropical regions of Africa and South Asia where it evolved as a distinct culinary herb. During the 18th century, American gardeners adopted and cultivated the variety, integrating it into North American herb traditions where it has remained a steady presence ever since. The plant's fuzzy stems earned it the regional name 'Hairy Basil' in some seed-saving circles, a descriptor that has persisted alongside lime basil in heirloom seed catalogs. Its preservation as an open-pollinated heirloom reflects the work of gardeners and seed savers who recognized that this unique basil offered something irreplaceable that modern breeding programs had not replicated.”
