Lemon Basil has long been a staple in Indonesian kitchens where its vibrant citrus aroma is used to enliven soups, curries, and grilled meats. Though its exact origins are difficult to trace, this heirloom variety has been passed down for generations and remains a go-to choice for its culinary and medicinal qualities.
A heat-loving herb that thrives in full sun, it forms tidy 8–16″ plants with a bushy, compact shape and spreads up to 20″ wide. The bright lime-green leaves are narrow, elliptical, and finely serrated, measuring 1½–2″ long. When left to flower, the plant produces delicate white blossoms that add ornamental charm to the garden.
The flavor is distinctly citrusy with tangy undertones, adding freshness to a variety of dishes. A staple in Indonesian cuisine, Lemon Basil enhances soups, pasta, and sauces. Its citrusy essence pairs wonderfully with grilled fish, shrimp, chicken, and other meats, while the leaves can be rubbed directly onto meats for a subtle infusion or used to flavor oils and vinegars.
For a creative twist, it can also be used in baked goods such as cookies, pies, and cakes, where it adds a light citrus touch. The edible flowers, with their intense blend of basil and citrus flavor, can be used in any recipe that calls for basil or as a garnish for drinks, salads, soups, pasta, and desserts.
It holds up well after picking and can be frozen or dried for long-term use, with freezing offering the best preservation of its essential oils and fresh citrus flavor. Rich in vitamin K and moderate in beta-carotene, it also contains potassium, manganese, iron, and magnesium. It’s a healthy and flavorful addition to the herb garden.
Planting Instructions for Basil – Lemon Seeds
When to Plant:
Start Lemon Basil seeds indoors 3–4 weeks before your last expected frost date to get a jump on the season. In warm climates, you can also direct sow outdoors after all danger of frost has passed and nighttime temperatures stay consistently above 50°F (10°C). For a continuous harvest, sow new batches every 3–4 weeks through midsummer.
Where to Plant:
Lemon Basil thrives in full sun and needs at least 6 hours of direct light daily. Choose a warm, sheltered location with well-drained, nutrient-rich soil. If growing in containers, use a high-quality potting mix and ensure your pot has drainage holes. Raised beds and greenhouses are also excellent options, especially in cooler regions.
How to Plant:
Sow Lemon Basil seeds ⅛″ (3 mm) deep either in seed trays or directly into garden soil. For direct sowing, space seeds 6–8″ apart and later thin seedlings to 10–12″ once they’ve grown a few sets of leaves. Indoors, transplant seedlings once they reach 3–4″ tall and have at least two sets of true leaves. Before transplanting outdoors, harden off the seedlings by gradually acclimating them to outdoor conditions over the course of 7–10 days. Begin by placing them outside in a sheltered, shady spot for a few hours each day, slowly increasing their time outdoors and exposure to direct sunlight and wind. This process helps reduce transplant shock and ensures the plants adjust well to life outside, especially if moving from a warm indoor space to variable spring weather.
Growing Tips:
Water regularly but avoid soggy soil. Lemon Basil appreciates steady moisture, especially in containers, but hates wet feet. Use mulch to conserve soil moisture and suppress weeds. Avoid overhead watering to prevent fungal issues. Pinch off the top set of leaves regularly to encourage bushier growth and delay flowering. Apply a diluted liquid fertilizer every few weeks or work in compost to keep plants vigorous. Afternoon shade can help prolong harvest in hot climates.
Harvesting:
Begin harvesting once the plants are 6–8″ tall. Pick leaves regularly, starting from the top down, to promote branching and ongoing leaf production. Cut just above a leaf node to encourage new shoots. Remove any flower buds promptly unless you’re saving seed, as flowering reduces leaf quality. Toward the end of the season, harvest entire stems before the first frost is expected. You can use fresh leaves immediately or preserve them for later use.
Storage:
Use Lemon Basil fresh for the best flavor. Store short-term by placing stems in a glass of water at room temperature. Avoid refrigeration, as cold temperatures cause the leaves to blacken. For long-term use, preserve Lemon Basil by freezing or drying. To freeze whole leaves, blanch them in boiling water for 3–4 seconds, transfer to an ice bath, dry thoroughly, then pack flat in plastic wrap and seal in a freezer bag for up to 3 months. You can also chop fresh Lemon Basil and mix with olive oil, then spoon into ice cube trays, freeze solid, and store cubes in resealable bags—ideal for sauces, soups, or vinaigrettes. For drying, use a dehydrator at 95°F (35°C), an oven at its lowest temperature with the door propped open, or hang bundles in a dry, well-ventilated place. Once dried and crumbly, store leaves in airtight containers away from light. Use within 6 months for best flavor.
Companion Plants:
Lemon Basil grows well with tomatoes, peppers, lettuce, chamomile, and oregano. Avoid planting near rue or sage, which may inhibit its growth.
Seed Saving:
To save seeds, allow a few basil plants to flower and go to seed. Once seed heads dry and turn brown on the plant, cut and store them in a paper bag. Allow them to dry fully in a cool, shaded area before threshing. Store cleaned seeds in a labeled envelope in a cool, dry place for next season. We also offer seed-saving envelopes for sale which include a designated space to write the variety name and harvest date, making them a convenient option for organized storage.
FAQ:
What makes Lemon Basil different from other varieties?
Lemon Basil is uniquely defined by its vibrant citrus aroma and tangy flavor, which contrast sharply with the sweet, clove-like notes of common basil.
Is Lemon Basil suitable for container gardening?
Yes, Lemon Basil is well-suited for container gardening thanks to its compact, bushy growth habit.
What are the appearance and growth characteristics of Lemon Basil?
Lemon Basil grows into a compact, bushy plant that stands 8–16 inches tall and spreads up to 20 inches wide. It features bright lime-green, finely serrated leaves about 1½–2 inches long, and produces dainty white flowers that are also edible.
How productive is Lemon Basil, and when should I harvest it?
You can begin harvesting Lemon Basil once the plant is well established, usually around 6–8 inches tall with several sets of leaves. Choose vibrant, healthy leaves and avoid any that are discolored or damaged. Regular harvesting encourages bushier growth and higher yield. For the best flavor, pick leaves before the plant starts to flower, though you can continue harvesting throughout the season as needed.
When is the ideal time to plant Lemon Basil?
Lemon Basil thrives in warm weather and should be planted after the last frost date. Start seeds indoors about 6 weeks before your final frost, or direct sow once soil temperatures are consistently between 65–85°F.
How is Lemon Basil commonly used in cooking?
Lemon Basil is a staple in Southeast Asian dishes, especially Indonesian cuisine. It enhances soups, curries, grilled meats, and seafood. It also adds a citrusy twist to pasta, sauces, herbal vinegars, and even baked goods like cookies and cakes.
What’s the best way to store Lemon Basil after harvest?
To store fresh Lemon Basil short-term, wrap the leaves in a damp paper towel and place them in a sealed bag or container in the refrigerator. For long-term use, finely chop the leaves, pack them into ice cube trays, top with olive oil, and freeze—perfect for adding to cooked dishes. You can also dry the leaves by air drying, using a dehydrator set to 95–115°F (35–46°C), or placing them in a low-temperature oven. Once fully crisp, crumble and store them in an airtight container.
What are the nutritional benefits of Lemon Basil?
Lemon Basil is a good source of vitamin K and contains moderate levels of beta-carotene. It also provides minerals such as potassium, manganese, iron, and magnesium—making it both a flavorful and health-supporting herb.
Are there any special growing or seed-saving tips for Lemon Basil?
Because Lemon Basil has a lower germination rate, sow extra seeds to ensure good coverage. It’s sensitive to frost and needs consistent moisture. To save seeds, allow flower stalks to dry, then collect and store them after shaking the seeds free in a paper bag.
