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. It is not known for being invasive and can be easily controlled in a garden setting.CC BY-SA 4.0
