Desmanthus cooleyi, commonly known as Cooley’s Bundleflower, is a perennial subshrub or herb that can be deciduous or semi-deciduous. It is native to open woodlands, prairies, and grasslands in the Southwestern United States and Northern Mexico. This plant typically grows to a height of 0.7-2 feet (0.2-0.6 meters) and a width of 1-2 feet (0.3-0.6 meters), featuring fine-textured foliage and a bushy growth habit.

Cooley’s Bundleflower is valued for its delicate, bipinnate leaves and its small, spherical flower heads that bloom from late spring to early fall. The flowers are a combination of white and yellow, creating a subtle but attractive display. This plant is drought-tolerant and thrives in full sun to part shade, making it suitable for xeriscaping and naturalized areas. It is often used in restoration projects and as a component of native plant gardens. Cooley’s Bundleflower prefers well-drained soils and requires minimal maintenance once established. It is not commonly affected by diseases or pests, but overwatering can lead to root rot.CC BY-SA 4.0
