Populations of Delphinium stachydeum are widely scattered in isolated mountain ranges surrounded by desert or grassland. The species has been reported (visual sightings) from northwestern Utah; no specimens have been seen from there. Hybrids between D. stachydeum and D. glaucum have been reported. Although D. stachydeum has been seen flowering within 30 m of flowering D. depauperatum, no hybrids have been observed.
Delphinium stachydeum may possibly be confused with D. geyeri, from which it may be distinguished by its usually greater plant size, less pubescent foliage, and later flowering date. Delphinium stachydeum also may be confused with D. glaucum; see discussion under that species.
