Phenology: Flowering Jan–May.

Discussion
The name Crossosoma parviflorum was based on specimens from the north side of the Grand Canyon and Sonora, Mexico, and applied to plants with somewhat smaller flowers and fruits than those in most other populations. Further taxonomic research may determine that this constitutes a valid infrataxon; it has not been accepted for the present treatment. Although it is available through specialty nurseries, this species is seldom seen in southwestern gardens as a specimen plant and ornamental.
Selected References
None.
