This hardy heirloom is the old-fashioned blue flowered variety, and used to be called corn flower. Adored by bees, butterflies and other pollinators, it grows 3 feet tall and blooms all summer. A wonderful cut flower (it is the canonical lapel flower), the 1-1.5” blossoms also are edible, with a light, spicy clove-like flavor. Flowers make attractive blue food dye, and have medicinal value.
Direct seed in early spring, when soil temp is at least about 60 degrees °F. Sow 1/8" deep and cover lightly or tamp down. Thin to 6-9” apart. Grows well in average, well-draining soil and full sun. Self-sows readily.
