Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 2 seed accessions of Penstemon albomarginatus from 2 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass an unknown number of maternal plants
Penstemon albomarginatus is known from three widely disjunct locations: the Mojave Desert of southern Nevada, the Mojave Desert of southeastern California, and the Sonoran Desert in western Arizona. Rare in California (fewer than five extant occurrences), but occassionally locally abundant elsewhere. The primary threat to this species is habitat degradation due to land-conversion.
18 known populations, with individuals numbering in the thousands.

Genetic studies of clusters in the field could determine if each group was clonal.
More propagation studies should be carried out to determine if seedlings, cuttings, or transplanted plants could be used for mitigation efforts.
