Identify my basil 'osmin'

There are many varieties, often with diverse flavours, including "cinnamon", "licorice", "lemon", "Thai", "purple", "mammoth", "large green"... A plant typically measures between 20 to 60 cm high, with spear-tipped, oval leaves that grow 2 to 3 cm in length. The leaves may be light or dark green, or even purple for some varieties. The straight, branching stems are square in cross-section, like many labiates. The small, white flowers are bilabiate, with the upper lip separated into four lobes. They are small in size, and grouped in long, tubular, elongated bunches.

You can buy your seeds from a store or collect them each year after your basil has flowered — providing you didn't buy an F1 cultivar to begin — in order to sow them the following season.
You can sow directly in place, starting in April for southern regions, or in May for other regions — the seeds will sprout once temperatures approach 18°C.
Sow in light, well-drained earth, placing a few seeds in each seed hole, spaced 20-30 cm apart. Barely cover with earth or potting soil, as the seeds are extremely small.
Water with a fine mist.
Keep the soil moist during the first few weeks after sowing.
You can also sow basil under a cold frame, from February to April.
Do not cover the seeds that need light to germinate - just sprinkle a little potting soil on them. Put the seedlings in a clear room with a temperature of around 18 ° C. Behind the kitchen window, it works pretty well: just avoid full sun and big temperature differences. Keep the soil moist for the first few weeks, but never soggy, spraying gently and regularly.
