Blue flowers are always welcome in the garden and Borage is one of the most reliable sources, often flowering lavishly about eight weeks after sowing and continuing until the first serious frosts. It grows best in full sun where it tends to have a more compact habit, but it easily tolerates a partial sun exposure. Although the flowering period is typically June to September, many plants extend that period.
The plants will happily grow in just about any soil type as long as it drains well and likes to be kept somewhat moist throughout the growing season.
Borage is a very important flower for both bees and beekeepers. The flowers which grow around the stem appear from early spring right through to autumn, provide both pollen and nectar in prodigious amounts throughout the season.
Garden visitors can be converted to herbal advocates simply by offering a taste of its white flower. They are pleasantly surprised to find it has a definite but subtle cucumber aftertaste. The edible, star shaped flowers add an unusual touch to summer salads and cakes, or can be used to decorate summer drinks like Pimms and cordials.
Sowing: Sow early/ late spring indoors or direct in mid to late spring.
Borage can be sown early indoors or directly outdoors once the soil has warmed. It is not suitable for container growing as it has a very long tap root.
Sowing Indoors. Sow in January to February…normally 4 to 8 weeks before planting outside.
Sow at 1.5mm (1/16in) deep in pots or trays in a good seed compost. Make sure the compost is moist but not wet and seal inside a polythene bag until germination which usually takes 5 to 21 days at 21°C (70°F).
Transplant the indoor seedlings when large enough to handle into boxes, spacing them 5cm (2in) apart. Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out after all risk of frost 15cm (6in) apart in full sun and ordinary well-drained soil.
The young borage must be handled carefully; especially when it is being transplanted from one place to another as it has a very long tap root that is easily damaged.
Sowing Direct. Sow in March to April.
Prepare the area well, marking the area to be sown with sand, Sow to a depth of 3mm (1/8in). Space 10-15cm (6in) apart. Water in well. Once seeds have germinated, check and thin out if necessary, any seedlings may be transplanted. The plants will grow quite fast and are quite recognisable from weeds, continue to water throughout periods without rain.
External contact with fresh borage leaves may cause skin rashes in some sensitive persons. The prickly hairs can be irritating so you may wish to use gloves when handling the plant.
