Penstemon superbus

P. superbus is a remarkable plant that is used extensively on the West Coast for erosion control and natural landscaping. We love it for its ridiculously tall spikes of coral red flowers and large glaucous leaves. Hummingbirds love it too! Self-seeds readily.

Hudson Valley Gardeners: We will be the first to admit that Penstemon are not particularly easy plants to grow in the Northeast. They are easy in their first growing season, but they need fertile yet exceptionally well-drained soil in order to establish successfully. They also need some level of protection from drying spring winds. We think they are worth the effort as they make a wonderful addition to the low-water garden. Additionally, it is easy to maintain a continual supply by taking cuttings.
