Thymophylla pentachaeta var. belenidium, commonly known as Fiveneedle Pricklyleaf, is a deciduous perennial subshrub or herb. It is native to arid and semi-arid regions, particularly desert scrub and grasslands in the Southwestern United States and Northern Mexico. This plant typically grows to a height of 0.5-0.7 feet (0.15-0.21 meters) and a width of 0.3-0.6 feet (0.09-0.18 meters). It has a compact form with finely dissected, needle-like leaves and produces bright yellow, daisy-like flowers that bloom profusely in the spring, summer, and fall, adding a long-lasting splash of color to the garden.

Fiveneedle Pricklyleaf is valued for its drought tolerance and extended flowering season, making it an excellent choice for rock gardens, xeriscaping, and as a ground cover in hot, dry climates. It thrives in full sun or partial shade and requires well-drained soils. While it tolerates medium amounts of water, it is highly adaptable to low-water conditions once established. This plant is not commonly affected by diseases or pests, but overwatering can lead to root rot.CC BY-SA 4.0
