Basil Dark Opal - Ocimum basilicum Purpurascens
Received the packet. We will see if the seeds were of good quality when I sow them next year. The trust I had in Promise of Flowers for years has been lost after several quite neglected orders, plants in bad condition, scams...

'Dark Opal' Basil is a stunning variety with large, deep purplish red leaves with slight violet hues. It will look and taste great in salads. Its cerise pink flowers contrast beautifully with its dark leaves. Sow from March to May and harvest as and when required from June to October.
Basil is native to the tropical regions of Asia and Africa and has been used in the Mediterranean region since Antiquity. Romans hailed it as the symbol of love... whereas Ancient Greeks considered basil to be the plant of hatred and misfortune! Depending on the variety, plants will reach 30-50 cm in height. Like most members of the Lamiaceae family, the erect, branched stems are square. The leaves of this delightful herb can be eaten fresh or dried. They are widely used in salads, marinades or pesto to accompany pasta, meat or fish. As well as being rich in essential oils, basil has anti-bacterial, anti-inflammatory and stimulating properties.
Harvesting and storage: for immediate use, harvest the leaves as and when required from July to October. Basil will stay fresh for a few days in a glass filled with water, away from direct sunlight. It can also be dried and kept in an airtight jar, although it will inevitably lose some of its aroma.
Good to know: Basil benefits from a supply of well-rotted compost (3 kg/m²) in late autumn or early spring. Weed and hoe regularly to keep the weeds down. Pinching the flowering stems will lead to a bushier plant. The smell of basil leaves is a well-known mosquito repellent!

Botanical data
Sowing:
Basil likes a cool, moist, well-drained soil. It does best in part-shade as direct sunlight tends to burn the leaves. Basil can be grown both in the vegetable garden or in a pot in the veranda or on the balcony.
Direct sow in the Spring, from March to May. Lightly scatter the seeds in shallow furrows, about 10 cm wide and 2 cm deep. Leave about 25 cm between each row. Cover with soil and gently water. When the seedlings appear 10-15 days later, thin out the weakest ones. For longer harvests, stagger your sowing.
Alternatively, sow the seeds in pots and transplant when the seedlings reach about 10 cm in height (4-6 leaves). If you have a sunny spot in your kitchen such as the window sill, you can also choose to leave the basil in the pot to keep it closer to hand!
Care:
When the soil gets too dry, make sure to water your basil plants. Lack of water (hydric stress) will make them go to seed. Preventive mulching is also a good idea. Pinch out the flower heads as soon as they appear to encourage the plant to put out new leaves.
Basil is susceptible to powdery mildew, bacterial leaf spot and aphids. You can reduce the chances of this being an issue by watering your plants less often and thinning out the rows. Protect your plants from aphids by spraying them with a mixture of water and olive oil.

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).
