Phenology | Flowering spring. | Flowering summer–fall (year-round). |
Habitat | Sandy to gravelly or rocky grasslands, open oak, juniper, or pine woodlands, desert scrub. | Sandy pine woods, on white sand. |
Elevation | 900–1400 m. (3000–4600 ft.) | 0–30 m. (0–100 ft.) |
Distribution |
AZ; NM; Mexico (Chihuahua, Sonora)

Discussion | Plants of Dalea pulchra are attractive in flower. The spikes shatter quickly at anthesis; legumes and seeds are seldom seen. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Dalea feayi occurs in xeric soils and generally does not grow in the same habitats as D. carnea. In Florida, the species is frequent in the peninsula and central panhandle regions. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
