Penstemon grandiflorus LARGE-FLOWERED BEARDTONGUE
Also called “showy beardtongue” due to its succulent, leathery looking, gray-blue leaves and big tubular flowers up to 2 inches long! It makes this perennial one of the showiest North American beardtongues ever. Flowers are usually light pink or purple, and the plant structure is strictly upright. Great as a cut flower when the stalks are dying back. Great pollinator and hummingbird plant.
The best use is in a dry garden or xeriscape, paired together with other drought loving or tolerant perennials like Asclepias tuberosa, Asclepias verticillata, Coreopsis, Echinacea tennesseensis, Dalea, Oenothera or grasses like Sporobolus heterolepis or Stipa. Due to the shorter blooming period, this gem is often placed close to other bigger plants.
