Phenology: Flowering spring.
Habitat: Slopes in grassland and open oak woods
Elevation: 150-1200 m
Discussion
Tetraploid individuals of Delphinium gypsophilum subsp. gypsophilum occur intermingled with diploid individuals and are normally indistinguishable morphologically (H. Lewis et al. 1951).
Hybridization may occur with Delphinium recurvatum in the San Joaquin Valley, with D. parryi in the southern Coast Ranges, with D. hansenii in the foothills of the southern Sierra Nevada and the Tehachapi Mountains, and probably with D. hesperium subsp. pallescens in Coast Ranges. For a summary on the possible hybrid origin of D. gypsophilum, see H. Lewis and C. Epling (1959).
