Variety flavoviride is a widespread, infrequent to common, warm-desert shrub found on the Mojave and Sonoran deserts in southern San Bernardino, Riverside and San Diego counties. The yellowish-green hue of the flowering stems, inflorescence branches, and leaves readily distinguish it from var. polifolium, with which it occasionally occurs (especially in Mexico), although this feature is not always obvious on herbarium specimens. Variety flavoviride is much more attractive in the garden than its more frequently planted Mojave Desert counterpart. Reports (e.g., R. S. Felger 2000) of var. fasciculatum along the coast in extreme northwestern Sonora are based on specimens of var. flavoviride.
