The above propagation data sourced from Claude AI

Pre-treatment: Scarification of seeds using a five-minute treatment in 98% concentrated sulfuric acid or sandpaper. Further studies are underway for other treatments.

Establishment: The plant is native to portions of the Great Basin, Colorado Plateau, and northern Mojave Desert in the states of Arizona, California, Nevada and Utah at elevations ranging from 3,000-7,500 feet above sea level. Rhizobial strains that inoculate other perennial Dalea species may be effective at nodulating D. searlsiae, but this has not been evaluated.
