Botanical Name:
Penstemon palmeri
PEN-steh-mon PALM-er-eye
Common Name: Palmer's penstemon
Genus:
Penstemon
Palmer's penstemon is much more than the typical sharp, prickly, gray-leaved plants that come to mind when we think of desert plants. This southwestern native thrives in the harshest conditions and is a true showstopper when in bloom in late spring or early summer. The snapdragon-like pale pink flowers have a sweet-honey scent and are a favorite among bumblebees. Its attractive toothed, sage green leaves skirt each plant's upright stems the remainder of the gardening season.
This perennial wildflower is one of the largest and most dramatic penstemons. Because of its height, Palmer's penstemon can be used in the back of the border or as a focal point near a patio or walkway where its fragrance can be enjoyed. In an informal planting, it looks great planted alongside other native penstemons and grasses. The best rule of thumb for this or any other waterwise plant is to group it with others that have similar maintenance and water requirements.
Noteworthy characteristics:
This native of the southwestern U.S. is drought tolerant, tall, and has fragrant flowers.
Care:
Provide full sun and lean, sandy, well-drained soil. Plant with the crown an inch or two above the soil surface. It will not tolerate extra water, fertilizer, or mulch. Deadhead to maintain a tidy appearance. This plant can be short-lived; allowing a few flowers to go to seed and self-sow can help prolong its stay.
Propagation:
From seed or by division.
