General: Desert Marigold (Baileya multiradiata) is a perennial forb with relatively large, showy, bright yellow daisy (composite) flowers that can turn the landscape yellow during a good year, but can bloom at any time of year when conditions permit.

The ray flowers are numerous (at least 15), the involucre is wide (7–25 mm diameter), and there is one flowerhead per peduncle (flower stalk). Therefore not Laxflower (Baileya pauciradiata).

Furthermore, most of the leaves are near the ground, the ray flowers are long (more than 10 mm), oblong, and clearly 3-lobed. Style tips blunt. The peduncles are long (at least 10 cm) and leafless. Therefore not Woolly Desert Marigold (Baileya pleniradiata).

Desert Marigolds are common components of the spring wildflower display along washes and on bajadas in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) life zones.
