Liatris aspera, or Rough Blazingstar, is perfect for medium or dry well-drained soils. Shorter than other Blazingstars, the stalks are covered with lavender blooms in late summer. Butterflies are likely visitors, along with hummingbirds and other pollinators.

Ideal for dry perennial borders, rock gardens or low-growing dry meadows, it combines beautifully with Butterflyweed, Dotted Mint, Showy Goldenrod, Sky Blue Aster and Little Bluestem. This drought tolerant Liatris likes well-drained, dry to medium soils, or sandy and rocky situations. Avoid planting it in moist soils, or locations where the soil remains consistently wet during winter.

The species name, aspera, is Latin for "rough" which refers to the short stiff hairs on the central stem and the narrow basal leaves. Another distinguishing feature of Rough Blazingstar is the slightly zigzag stem. Other common names include Button Snakeroot and Rough Gayfeather.
