Liatris acidota, commonly known as Gulf Coast gayfeather, is a perennial herb native to the coastal prairies and savannas of Louisiana and Texas, where it thrives on sandy to clay soils. It grows from rounded corms to hairless stems that typically range from 8-35 inches tall, although some specimens can reach up to 51 inches. The plant is characterized by its dense spikes of showy purple flowers that bloom from June to October, attracting a variety of pollinators. The seeds of Liatris acidota are borne in small, dry, one-seeded fruits called cypselae.

Gulf Coast gayfeather is valued for its vibrant flower spikes, which provide visual interest in naturalistic plantings, prairie restorations, and wildflower gardens. It is also used in cut flower arrangements. This species is well-suited to cultivation in full sun and requires well-drained soils. While it is drought-tolerant once established, it benefits from occasional watering during prolonged dry periods. It is generally low-maintenance, but can be susceptible to root rot in poorly drained soils.CC BY-SA 4.0
