Penstemon
cobaea
“Showy Beardtongue”
With the largest flowers of the genus Penstemon, this mid-western species
is native to our grasslands, easy to grow, very long blooming and, unlike
many Penstemons, is long lived. The 2” long, flaring blooms are
so large, this Penstemon is often mistaken for a foxglove. The color
is variable, from flashy rich purple to rosy-violet. Bloom time is April
thru June, the flowers held in tight clusters atop 24” to 30”
stems. The evergreen foliage is an attractive, glossy, rich green. Though
it prefers loamy, well drained soil, it does tolerate drought conditions.
Attracts bumblebees & hummingbirds!
