Description
Thai Basil (Ocimum basilicum var. thyrsiflora) is one of the most fragrant basils for Asian cuisine, with an aniseed-like, spicy, and slightly liquorice aroma. In our climates, it is grown in the sun as an annual plant, which will quickly form a beautiful leafy clump to cut all summer. It is easy to grow from organic seeds to plant in the vegetable garden, in a herb square, or in a container on the terrace. Use to replicate the authentic taste of Thai or Vietnamese curries and soups.
Thai basil belongs to the Lamiaceae family, like mint or thyme. The Thai type is generally attached to the group Ocimum basilicum var. thyrsiflora. It was selected in Southeast Asia, notably in Thailand, Vietnam, Laos, and Cambodia. It is a short-lived perennial in a tropical climate, but it behaves as an annual in Europe: it can be sown each spring, grows quickly, flowers in summer, and dies at the first frost. It is a traditional variety, passed on and resown by gardeners, with reproducible seeds.
The plant forms a small upright bush, well-branched from the base, with quadrangular stems tinged with purple. In open ground, a well-nourished young plant commonly reaches 40 to 60 cm in height and 20 to 40 cm in width; in a pot, the clump rarely exceeds 30–40 cm. The leaves are ovate to lanceolate, quite narrow, shiny, dark green, subtly veined with purple. Their texture is firmer than that of 'Grand Vert' basil: they withstand cooking better and retain their aroma in hot dishes. Their aroma is powerful and complex, strongly aniseed-liquorice, with notes of clove and sometimes tarragon, very unique.
In summer, if the stems are allowed to lengthen, they bear terminal spikes of small purple to lavender, nectar-rich flowers. After flowering, tiny black achenes containing the seeds form, which are easy to harvest for the following year. The above ground vegetation disappears at the end of the season.
In several tropical countries, concentrated infusions of basil, including Thai basil, are used as an insecticidal or natural repellent against certain insects in crops and to protect stored goods.
In the garden, Thai basil is perfect planted near the kitchen, in a pot on the terrace or at the edge of the vegetable garden, where it can be easily harvested. It will make a beautiful combination paired with other world cuisine herbs, such as a purple basil like 'Dark Opal', coriander 'Marino' and Madagascan lemongrass (Cymbopogon citratus) for an Asian herb container, or with a mint 'Ginger' and a very long sweet pepper from the Landes in a large container. In the vegetable garden, it can be planted between tomatoes, aubergines, or peppers.
Harvest: Between July and October, basil is harvested as needed and as it develops.
Preservation: basil keeps for a few days in a cool place in a glass filled with water. It can be dried in the shade and stored in an airtight jar, but it then loses a little of its aroma.
The Gardener's Tip: weed and hoe regularly. Pinch out flowering stems so that new shoots develop. The smell of its leaves repels mosquitoes.
Organic or "AB" seeds come from plants grown in organic farming (without the use of plant protection products). They undergo no treatment after harvest. These seeds are suitable for organic market gardening.

Planting and care
Sowing and care:
Thai basil prefers a moist, loose soil, rich in humus. This plant also requires a fairly sunny position to develop well. Basil is sensitive to direct sun exposure which can scorch the leaves. Basil is typically planted in the vegetable garden, but it adapts very well to a pot in a conservatory or on a balcony.
Sowing: Sow in spring, during March, April, and May, directly in position. Sow well-spaced in a row, in a flat furrow about 10 cm wide and 2 cm deep. The rows should be spaced 25 cm apart. Cover the seeds with the soil removed along the furrow, then water. Germination takes between 10 to 15 days. As soon as the first young plants appear, thin lightly. The more you stagger the sowing, the longer the harvest period will be. You can sow in a pot for later transplanting once the young plant reaches 10 cm (4 to 6 leaves) in height. Basil can stay in a pot to be kept handy in the kitchen if it is well-lit.
Care: Basil simply requires watering (or preventative mulching) when the soil dries out. It is a lack of water (water stress) that can cause basil to bolt to seed. Pinch off the flower heads as soon as they appear to encourage leaf production. Basil is susceptible to powdery mildew, grey mould, and aphids. To combat moulds and powdery mildew, reduce watering and thin out the planting. You can treat the young plants with a mixture of water and olive oil to protect against aphids.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
