How to grow Penstemon
Choose a sunny position with some shade sheltered from cold winds with well-draining soil Water well until the plants are established, then reduce to watering to keep the soil moist. Mulch with well-rotted manure or garden compost each spring to get the best growth results, and apply some general-use fertilizer if growing in containers. Remove spent flower spikes as the blooms fade to help encourage new growth throughout the year. After about five years, penstemons often need replacing as they become woody and flowerless If you are growing your plants in containers, wrap them with a couple of layers of bubble plastic to protect the roots from winter frosts.
