The Story
Plant Bio
Ratibida columnifera, Mexican hat, is an upright clumping perennial native across North America, reaching about one to three feet. Its flowers are unmistakable: a tall columnar brown central cone up to two inches long, with a few drooping ray petals in yellow, mahogany-red or bicolour hanging beneath it like a sombrero brim.
The elongated cone is what sets it apart from every other prairie daisy, and it flowers over a long summer season on finely divided foliage. It is short-lived as an individual plant but self-sows freely, so a colony persists by continually replacing itself rather than by individual longevity.

Planting
How to Grow
- Sow or plant in spring in well-drained, lean soil.
- Choose full sun; it needs it.
- Space about eighteen inches apart.
- Water to establish, then rarely.
- Let some flowers set seed to maintain the colony.
- Cut back in late winter.
Pro Tip
Let it self-sow — individual plants are short-lived, and a colony only persists if you leave some seed heads to replace them.
