Growing Notes

Full sun and sharply drained, lean, gravelly, alkaline ground. It is a roadside and wash plant in the wild and it wants those conditions: poor soil, sharp drainage, no summer water. Space about 2 feet apart. Do not plant it in an irrigated bed, which is the most common way it is lost.

Maintenance

Leave the stems standing over winter, then cut back in late spring, leaving about a third. Let it self-sow; it is short-lived, often three or four years, and a stand persists through seedlings rather than old plants. Palmer’s penstemon will not tolerate fertilizer and prefers little to no irrigation; however, if the leaves are dehydrated for too long or start to brown, give it a deep watering to revive it.
