The richly colored, deep cobalt-blue and lavender flowers of Penstemon mensarum will leave you in awe. When planted with other late spring bloomers like lemon-yellow Achillea “Moonshine” and red Salvia greggii “Furman’s Red”, you will have a traffic- stopping color combination.

Grand Mesa Beardtongue grows to form a sturdy semi-woody plant with deep glossy green foliage. A long-lived Penstemon when grown in a lean, well- drained soil where it gets a lot of sun.

Clip off the bloomed-out flower spikes right at their base, then thin out and shape the stems at the base of the plant for a profusion of flowers the next spring. Zones 4-8.
