Cotton Candy is a meadow rue that grows into a dense, narrow pillar of fine-textured foliage topped with wispy, fluffy lavender flowers. Unlike many leggy meadow rues, its flowers sit just above the leaves, so the plant looks balanced and full.
Its columnar shape adds height to small spaces without taking up much room, and the tall stems and long-lasting flowers are excellent for cutting. Deer and rabbits rarely bother it.
What it looks like
Airy, rounded clusters of tiny flowers made of fluffy, thread-like stamens in soft lavender pink, forming cotton-like puffs 3 to 5 inches across at the tops of the stems. The flowers sit just above the leaves. Foliage is finely divided, with small, rounded, lobed leaflets like columbine leaves, in medium green with a slightly bluish cast, densely covering the stems. The plant forms a narrow, columnar pillar 38 to 42 inches tall and 18 to 24 inches wide. At peak it looks like a tall green column topped with a lavender haze.
Growing it with lavender
Meadow rue prefers richer, more evenly moist soil than lavender, so plant it in a nearby border with some afternoon shade, where its airy flower sprays can rise behind lower plants.
Care
Grow in full sun to part shade in average to fertile soil that stays reasonably moist; afternoon shade helps in hot, dry spots. Hardy in zones 5-8; cut the flowering stems back after bloom if the plant looks tired, and leave it undisturbed once established.
