A tall, airy perennial that brings height, movement, and a naturalistic feel to borders. Slender stems carry clouds of lilac‑purple flowers from midsummer into autumn, creating a light, floating effect that pairs beautifully with grasses and late‑season perennials. A magnet for bees, butterflies, and even birds, it offers exceptional wildlife value and carries the RHS Award of Garden Merit for its reliability. Thrives in full sun, copes with dry spells, and self‑seeds gently to form elegant drifts over time. Perfect for prairie planting, gravel gardens, and adding vertical accents with minimal maintenance.
