You have to grow this heat-loving annual to really appreciate the beautiful, rose-like flowers. Lisianthus are native to the American Southwest, and this improved variety from Central America is taking gardens by storm. The 3-3 1/2" white petals are rimmed in rich purple. The narrow, upright plants grow 18-22" tall and look best-planted 7-10" apart. Can be grown in containers, in the middle of beds or in the cutting garden. Good vase life and unique silvery green foliage makes this durable annual a welcomed addition to fresh arrangements.
