Summary
Thymophylla acerosa, commonly known as Pricklyleaf Dogweed, is a deciduous perennial subshrub or herb native to arid and semi-arid regions, particularly the Chihuahuan Desert and other desert scrub areas in the Southwestern USA and Northern Mexico. It typically reaches a height of 0.8 feet (0.2 meters) and a width of 0.5-0.8 feet (0.2-0.2 meters). Pricklyleaf Dogweed has a compact, spiny form with needle-like leaves and produces bright yellow, daisy-like flowers from late summer into fall, which are quite showy despite the plant’s small size.
Pricklyleaf Dogweed is valued for its drought tolerance and ability to thrive in challenging conditions, making it suitable for xeriscaping and rock gardens. It is also used in border planting and as a ground cover in areas with poor soil. This plant requires minimal maintenance once established. It prefers full sun exposure and well-drained soils, and while it tolerates medium amounts of water, it is highly drought-resistant. There are no major diseases or pests associated with Thymophylla acerosa, but it can be sensitive to overwatering, which may lead to root rot.CC BY-SA 4.0
