Phenology | Flowering fall. | Flowering spring. |
Habitat | Open rocky hillsides and canyons, open pine or oak woodlands. | Sandy to gravelly or rocky grasslands, open oak, juniper, or pine woodlands, desert scrub. |

Discussion | Some herbarium labels comment on the lemon odor of Dalea lumholtzii. Although the epistemonous petals are generally blue or bluish, white-petaled plants are not uncommon in the flora area. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
