Mexican hat is a tough, drought tolerant, sun-loving perennial that thrives in nearly any well-drained soil. It grows about 18 to 20 inches tall and wide, though sometimes as tall as 30 inches. The deeply recurved flower petals are a russet to maroon red with yellow tips (though sometimes they are entirely red, or entirely yellow), and are topped by a prominent central disc, the entire effect reminiscent of the old hats worn during Mexican fiestas. Use in meadow or naturally-styled landscapes. Blooms June to July, and sometimes later. Foliage is finely cut and ferny, with a strong aroma when crushed.
Grow in full sun and well drained soil; not particular to soil type as long as it is well drained. It does spread and naturalize, so use where that is an advantage. Typically flowers in June and July, but may flower into August and September if periodic moisture is provided. Though the plant tolerates browsing and the foliage not appealing to deer, they will eat the flowers.
