Blazing Star (Liatris spicata): Description & Features
Product Description
Liatris spicata (Blazing Star / Dense Blazing Star / Gayfeather / Marsh Blazing Star) is a summer show-stopper known for its vertical purple bottlebrush spikes that open from the top down for a long, pollinator-packed display. Narrow, grassy foliage forms tidy clumps that stay clean through the season, while sturdy stalks bring height and rhythm to borders, meadows, and cutting gardens. A reliable native perennial for full sun and moist to average, well-drained soils (more moisture-tolerant than many Liatris), it delivers vivid color, movement, and exceptional wildlife value with very little care.

Care & Growing Information
- Site & Light: Plant in full sun for stout stems and maximum flower count.
- Soil & Water: Prefers well-drained loam to clay-loam; keep evenly moist in spring/early summer, then water as needed. Avoid chronically winter-wet soils to prevent rot.
- Planting: Set corms/crowns at prior growing depth; space 12–18″ for vertical impact and airflow.
- Maintenance: Deadhead for tidiness or leave seed heads for birds and winter texture. Cut back to basal foliage in late fall or early spring.
- Design Tips: Repeat in drifts for a cadence of vertical color. Pairs beautifully with coneflowers, rudbeckias, salvias, prairie grasses, and late asters. Excellent cut flower (fresh or dried).
