| Phenology Comments: | Flowering Apr-Jun. |
| Reproduction Comments: | |
| Habitat Comments: | Deep loose sandy soils in washes, flats, roadsides, steep aeolian slopes, and stabilized dune areas, with Ambrosia dumosa, Larrea tridentata, Pleuraphis rigida, Krameria parvifolia, Achnatherum hymenoides, Tamarix ramosissima, Tessaria sericea, Astragalus geyeri var. triquetrus, A. sabulonum, Eriogonum trichopes, Ephedra torreyana, Dicoria canescens, Pediomelum, Croton californicus, Sporobolus cryptandrus, Psorothamnus fremontii, Abronia, Tiquilia, etc. Can withstand moderate temporary disturbance. |
