Penstemon Fruticosus Var. Scouleri

Scouler’s shrubby penstemon is a compact western North American form allied to Penstemon fruticosus. Low woody stems spread among rocks and carry small, often serrated evergreen leaves, followed by generous tubular flowers in lavender, violet or blue-purple with pale interiors. The neat mounded habit and intense bloom colour make it an outstanding trough, crevice or rock-garden plant. Adapted to exposed mountain slopes and mineral soils, it tolerates cold and drought once established but needs full sun, free air movement and protection from stagnant winter wet.
