The Story
Plant Bio
Liatris, or blazing stars, are upright, clump-forming perennials native to North American prairies. They are known for their unique flowering habit, with blooms opening from the top of the spike downwards. Liatris aspera is distinguished by its 'button-like' flower heads arranged along the stalk, rather than the feathery plumes of other species. It is exceptionally drought-tolerant due to its deep corm and taproot.

Planting
How to Grow
- Select a site that receives full, all-day sun.
- Ensure the soil is very well-drained; amend with grit if needed.
- Plant corms 3-5 inches deep and 8-12 inches apart.
- Water once after planting to settle the soil around the corms.
- Provide minimal water once established; it thrives on neglect.
- Avoid mulching directly over the crown to prevent rot.
Pro Tip
Plant in lean, well-drained soil to prevent flopping; rich soil encourages weak, leggy stems.
Keep It Thriving
Care Guide
Do
- Provide excellent drainage; this is the most critical factor.
- Embrace its natural, wild look in prairie-style plantings.
- Leave spent flower stalks for winter interest and bird food.
- Pair with native grasses that help support the tall stems.
Don't
- Don't overwater or plant in a consistently moist location.
- Don't fertilize; it prefers poor, lean soils.
- Don't plant in shade, which will cause stems to stretch and flop.
- Don't worry about pests or diseases; it is remarkably trouble-free.
