HOW TO GROW
Sowing: Direct sow in late fall, planting just below the surface of the soil. For spring planting, mix the large flowered beardtongue seeds with moist sand and store in the refrigerator for 30-60 days before planting. Keep the soil lightly moist until germination. This Penstemon Grandiflorus seed can also be started indoors 6-8 weeks before planting in the spring.
Growing: Water seedlings until they become established. This plant develops rather slowly, and usually begins blooming in its second year. Mature plants tolerate drought well because of a well-developed tap root; this plant also has excellent resistance to disease and pests. This plant grows well in rocky or sandy soil. After blooming cut the plant back to several inches above the soil, unless seed is wanted. Do not overwater, since this plant is particularly susceptible to root rot if the soil becomes too moist. If seeds are not required, cut the plant back after blooming has finished. This plant often self-sows, and is highly attractive to bumblebees, hummingbirds, and butterflies.
Harvesting: For cut flowers, choose stems with flowers that have just opened. Strip the foliage that will fall below the water level, and place in water immediately.
Seed Saving: After the flowers fade, small pods will form that eventually open at the top to reveal the ripe seeds. Gather the seeds as soon as the pods have begun to open; watch them carefully to prevent loss, since the seeds can easily be blown away by the wind. Store the large flowered beardtongue seeds in a cool, dry place.
