Davis' pepperweed is a rare native perennial found in a very limited range across Idaho, Nevada, and Oregon, typically in sagebrush and semi-arid habitats. It is best grown in well-drained, gritty or loamy soil with moderate moisture and partial shade, mimicking its natural high-desert environment. This species is primarily of interest to native plant enthusiasts and conservation gardeners rather than the general home gardener.
