BeardTongues

Beard Tongue (Penstemon). There are many species of native Penstemons that range from tiny mats to large upright plants. Different species bloom from late spring to fall; most for short periods. This is a true American native with hundreds of species, all of which originated in North America or Mexico. Most can be grown in Descanso gardens, with care to soil, watering. Some need special conditions, such as screes, sand beds or low-water regimes

Locally, we have four species that bloom all over our road banks, open spaces and hillsides in late spring. You will find them along Boulder Creek Road as you drive toward Julian. They can all be grown in our gardens. They are: Scarlet Bugler (Penstemon centranthifolius), Chaparral Penstemon (Penstemon heterophyllus var australis), Cleveland's Penstemon (Penstemon clevelandii) and Showy Penstemon (Penstemon spectabilis).

2009 Plant Sale Offerings: Scarlet Bugler, Showy Penstemon and Foothills Penstemon grow in the wild with no suppplemental water. If you bring home any of these from or a native plant nursery, plant in our native gritty decomposed granite. Water about once a week until they settle in, then water only during severe dry spells. These all enjoy full sun.

BEARD TONGUE GARDEN HYBRIDS

Beard Tongue (Penstemon). There are many varieties and hybrids as well as many types and sizes. British and American gardeners have hybridized many showy varieties. Most hybrids bloom heavily in early summer with sporadic blooms through fall. There are several catalog sources for the named hybrids.

Hybrid plants found in local nurseries are easily at home in our Descanso gardens. They usually range from one to three feet. They do well in most soils, and are not as sensitive to conditions as the native species. Once established, they need little attention. Shown below is an unnamed hybrid and P. 'Blackbird'.
