How to grow
Drought-tolerant once established, penstemons are easy-care perennials suitable for most conditions. Plant in full sun in an enriched, free-draining soil. Water regularly during establishment and extended dry periods for improved flowering and performance. Prune back to a low mound after flowering to maintain a compact habit.
