Carphochaete bigelovii, commonly known as Bigelow’s Bristlehead, is an evergreen perennial subshrub or herb native to the Southwestern United States and Northern Mexico, where it is found in a variety of habitats including open woodlands, grasslands, and chaparral. It can reach up to 300 cm (10 feet) in height and is characterized by its upright growth habit. The flower heads are typically borne singly or in pairs on each branch, featuring disc florets that are generally purple with white lobes around the edge, but lacking ray florets. The flowering season extends through the late summer and fall, and while the flowers are not particularly showy, they do add a subtle charm to the plant’s overall appearance.

Bigelow’s Bristlehead is valued for its drought tolerance and its ability to thrive in challenging environments, making it a suitable choice for xeriscaping and naturalistic plantings. It is often used in restoration projects and as an ornamental in dry gardens. This plant prefers full sun to part shade and requires low to medium amounts of water, thriving in well-drained soils. Gardeners should be aware that it may require pruning to maintain a desirable shape and to prevent it from becoming too leggy. There are no significant disease or pest issues, but overwatering can lead to root rot.CC BY-SA 4.0
