Nowhere common, Delphinium parishii subsp. pallidum may be in danger of significant population reductions because of human encroachment.

Delphinium parishii subsp. pallidum hybridizes with D . parryi subsp. purpureum . It is frequently confused with D . inopinum . Most of the data attributed to D . inopinum in the paper by H. Lewis and C. Epling (1954) pertain to D . parishii subsp. pallidum . Refer to discussion under D . inopinum for features used to distinguish these two taxa. Plants of D . parishii subsp. pallidum might be confused with D . gypsophilum subsp. parviflorum . Distinguishing characteristics are found in discussion of that taxon.
