ITALIAN BUGLOSS 'DROPMORE' (Anchusa azurea): One of the truest blues for the summer border or container garden, bugloss makes airy clumps (1-4 feet tall by 18 inches wide) of narrow green leaves and numerous clusters of tiny azure blue blossoms. Cut back promptly when seedheads form and the plants may bloom several times more till frost. Hardy USDA Zones 3-8. For well-drained, clay-compost soils. Photo courtesy Bluestone Perennials.
