This small (18 inches tall and wide), shrubby perennial produces its fragrant blooms throughout the summer in blue, lavender, purple or white, depending on the cultivar. Heliotrope prefers moist, well-drained soil in full sun or, where summers are hot, in afternoon shade. Butterflies are attracted to its flowers, which offer a delightful vanilla scent. Bring container plants under cover for winter or take cuttings.
