White is useful in the mixed border as an exclamation point or accent, and the bottlebrush spikes of Liatris spicata 'Alba' will add vertical interest as well. It's an old-time favorite for summer gardens and bouquets that will attract butterflies and other pollinators. Plants self sow if not deadheaded, creating a charming, naturalized look.
Liatris is a North American genus consisting of about 20 species. They are excellent for cutting, superb for drying, and beautiful in the border, especially planted in groups. Butterflies will flock to the blooms. Plants thrive in full sun and moist, well-drained soil.
