Lavender - French / Butterfly
Lavender French is popular for its intense fragrance and its short dense flower spikes topped with conspicuous rich violet bracts.
Sow in trays of good seed compost in a propagator or warm place to maintain an optimum temperature of 60-65F (15-18C), just covering the seed with compost. Sow at any time of year. Germination can be slow. Transplant seedlings when large enough to handle into 7.5cm (3in) pots. Grow on in a cold frame and plant out the following spring. Space the plants 30cm (12in) apart in full sun.
Best grown in a warm position, sheltered from cold winds and frost. It is not fully hardy, but survives well in a sunny corner or against a warm wall, and makes an excellent container plant that can be brought under cover in winter.
