Dalea greggii, commonly known as Gregg’s prairie clover, is a perennial herb native to desert grasslands, mesquite savannas, and rocky hillsides in the southwestern United States and northern Mexico. It typically reaches about 2 feet in height and spreads to form a dense mound. Gregg’s prairie clover has compound leaves with small leaflets and produces spikes of purple flowers from late spring to early fall, which are highly attractive to pollinators such as bees and butterflies. The flowers are showy and add a splash of color to the arid landscape. Its woody stems and fine-textured foliage also contribute to its ornamental value.

Gregg’s prairie clover is valued for its drought tolerance and ability to thrive in poor, rocky soils, making it an excellent choice for xeriscaping and naturalistic plantings in arid regions. It is also used for erosion control on slopes and banks. In cultivation, it requires minimal maintenance, needing only occasional watering once established and full sun to part shade exposure. While it is generally disease-free, overwatering or poor drainage can lead to root rot. It is not known to have aggressive roots or other significant problems.CC BY-SA 4.0
