Penstemon angustifolius var. caudatus

This narrow-leaved penstemon variety is a fast-growing prairie native that produces stunning tubular blue to purple flowers beloved by hummingbirds and bees. Plant it in full sun to partial shade in well-drained, sandy or loamy soil and water moderately until established. It is low-maintenance once settled and performs beautifully in xeric or wildflower garden designs.
