The Large Flowered Beardtongue is one of the showiest Penstemon species in our garden. The large light purple tubular flowers are very attractive and are set off by the silvery-gray clasping leaves.
This native is very effective utilized in a mass planting, attracting many bee species who work their way up the tubular flowers. After the flowers are finished the silver foliage continues to be an attractive feature.
