Lace Flower · Didiscus · Annual Cut Flower

A refined and elegant cut flower, Trachymene coerulea ‘Lavender Blue’ produces soft, pale blue lace-like umbels with a gentle, clean fragrance. The delicate blooms are held high on stiff, upright stems, creating an airy and sophisticated look that works beautifully in both garden borders and floral arrangements.

In trials, ‘Lavender Blue’ blooms continuously for up to two months, making it an excellent choice for succession sowing and extended cutting periods. A favorite among florists for its texture, subtle colour, and long vase life.
