Blazing star
A North American prairie perennial with dense purple bottlebrush spires that open unusually from the top downwards, and one of the most heavily worked plants in a summer border. It is a mainstay of American prairie restoration and an outstanding butterfly plant as well.
Value to bees
- Nectar
- Very high
- Pollen
- High
- As a honey crop
- Not a honey source
- Which bees, and why
- The dense florets are shallow and accessible, and the spire form gives bees a great many flowers within a short walk. It is also a principal nectar plant for monarch butterflies on migration.
Dense shallow florets on an upright spire, accessible to short and long-tongued bees alike.
- Worth knowing
- An outstanding summer nectar source, and among the most heavily worked prairie plants.
Flowering
- In flower
- July to September (northern hemisphere)
A long midsummer to late-summer flow.
Growing it
- Conditions
- Full sun on moisture-retentive but free-draining soil. It grows from a corm and dislikes winter waterlogging.
- Size
- 60-120 cm tall.
- Native range
- Eastern and central North America, in prairie, damp meadow and open ground.
- Suits
- Small gardens, Large gardens, Meadow or wildflower area, Containers and window boxes
- Full sun is essential — it flops badly in shade.
- Grows from a corm; plant in spring and avoid heavy wet winter soil, which rots it.
- Leave the seedheads for goldfinches, which strip them thoroughly.
What it looks like
Grassy narrow leaves with dense upright spires of fluffy purple florets, opening from the top of the spire downwards — the reverse of almost every other spike-flowered plant.

Guides covering this plant
- How to make a garden genuinely useful to beesMost bee-friendly advice covers flowers in June, which is the one thing bees are least short of. The gaps are at the ends of the year — and half the problem is not flowers at all.
- A bee-friendly garden in the United StatesAround 4,000 native bee species and a continent too large for one planting list. What transfers is the method — regional natives, a long season and bare ground — rather than the species.
