Baileya multiradiata (Desert Marigold)

This fast growing, short-lived perennial is native to much of the Southwest, where it grows in sandy, gravelly soils. Bright yellow daisy-like flowers appear spring through fall and may bloom continuously at lower elevations. The blossoms are carried far above the rosette of wooly, silver-gray foliage on slender stems. This plant tolerates full sun, heat, cold and drought. Good drainage is essential. Although somewhat short-lived, it reseeds prolifically.
