Palmer's Penstemon

Penstemon palmeri

Plant Details:

Plant Type: Perennial
Plant Family: Scrophulariaceae
Plant Description: Upright herbaceous perennial native to the southwestern United States, with large light-pink flowers that bloom in clusters on tall spikes in early-summer. Waxy blue-green leaves grow on tall upright light-green stems sometimes tinged red. Grow in sandy or gravelly well-drained soils. Will not tolerate excess moisture and may suffer if smothered with mulch. Has a life-span of 3-4 years; after that time allow new seedlings to grow and take its place.


Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
