When to plant rocky mountain penstemon
Rocky Mountain penstemon is a long-lived perennial that blooms in mid to late spring; Colorado State recommends a full-sun spot with lean, well-draining soil and notes it self-seeds and needs only deep, infrequent watering once established. No explicit planting date is given, so a spring band is approximate.
Rocky Mountain Penstemon is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
