Penstemons are a large group of plants composed of many wild species found growing in a variety of climates, as well as numerous hybrids that have been developed for a wide range of characteristics. Available in every color from white to deep purple, Penstemon’s spikes of flowers are closely associated with hummingbirds, who prefer their nectar as a main source of food. Rock Penstemon’s flowers are coral to bright red, first appearing on short spikes in spring and then again from late summer into fall. This small to medium shrubby variety tends to keep its deep green foliage through the winter and the summer, when many other Penstemon varieties go completely dormant.
