|Mexican Hat is the common name for this wildflower with a dark red and yellow
bloom; Prairie Coneflower is the common name for the solid yellow bloom. Our
Ratibida columnaris is a mixture of both. This perennial grows one to three
feet in height and blooms from April to July and with a soaking or two, it
will bloom on till frost. It will grow in sand, loam, clay, caliche, and
limestone if well-drained. It likes full sun to part shade. We have seen
Mexican Hats blooming in full shade.
