Ocimum basilicum var. citriodorum
Lemon basil, lemon-scented basil, lemon basil, Thai lemon basil: its citrus note does not come from an added flavoring but from citral, the same molecule found in lemongrass and lemon zest. Its narrower leaves and lighter growth habit distinguish it at a glance from common basil.
Characteristics:
-
Lemon aroma: a citrus freshness layered over basil's aniseed base.
-
Fine foliage: leaves that are smaller and narrower than those of common basil.
-
More resistant: it withstands diseases better than most other basils.
-
Sensitive to frost: an annual in our climate, but it can be grown in a pot all year round.
Sowing advice:
-
Exposure: full sun and warmth. In the south, plant it outdoors from mid-April; elsewhere, a pot is preferable.
-
Soil: light, rich in organic matter, moist and well drained. Like all basils, it appreciates fertile soil that does not dry out—an addition of compost benefits it. It does not tolerate standing water.
-
Method: sow from April to June, in pots under cover at 20°C or directly in the ground after the last frosts, barely covering the seeds. Only move it outdoors once the nights are mild. See how to sow your seeds.
Planting advice:
- Transplant with 25 cm spacing, in the ground, in a pot, greenhouse, conservatory or behind a bright, sunny window.
Care advice:
- Water regularly at the base in the morning, without wetting the foliage.
-
The one step that makes all the difference: pinch out the stems above a pair of leaves and remove flower buds as soon as they appear. This makes the plant branch out and extends the harvest by several months.
Harvesting advice:
- Pick the leaves as needed, starting from the top. They freeze much better than they dry—the particularly volatile lemon note almost completely disappears when dried.
Beneficial companions:
Benefits for biodiversity:
- Let one or two plants flower at the end of the season: their white flower spikes are highly visited by bees and bumblebees.
- Its fragrance deters several pests from neighboring crops. See our repellent plants.
Uses:
- Its citrus note makes it suitable for uses where common basil falls short: fish, seafood, fruit salads, sorbets, lemonades and iced teas. It is also excellent in curries and Asian stir-fries. Always add it off the heat.
- A traditional medicinal plant, used in herbal medicine since antiquity. See our medicinal plants to sow.
Harvesting your own seeds:
Leave a few flower spikes to dry completely on the plant until they turn brown, then rub them over a container. Be careful: basils cross-pollinate very easily with one another. Isolate your seed plants if you grow several varieties, or you may lose the lemon note. See how to store your seeds.
