There are quite a few different species of Gayfeathers growing in stands across the fields, prairies, ditches, and woodland glades of Texas and North America. All are considered non-poisonous but only a few of them produce tubers big enough to be worth eating. Their tall, unbranching spikes start green, then erupt with many small, purple flowers, followed by browning as they dry. During the winter months clusters of these old stalks are easy spot, even through snow on the central plains. The drought-resistant Liatris spica are becoming popular in low-water xeriscapes and can often be found at big-box home improvement stores.

Gayfeather tubers continue to grow larger year after year but only the latest-year's portion is tender enough to eat, with the common species Liatris spica being considered the best. Memorize the location of the summer-blooming purple flower stalks for harvesting the tubers in the fall and winter. Once harvested, use these tubers as you would potatoes. They do well boiled or roasted.
