Penstemon confertus

 
Penstemon confertus
yellow penstemon
Common name yellow penstemon
Family plantaginaceae
Life cycle perennial (Z4)
Flowers creamy white-pale yellow (spring)
Size 16"
Cultural notes drought-tolerant

Mat-forming perennial, native to areas of the western U.S. and Canada. Even though its common name suggests a sunny hue, the flower spikes in spring appear to take on mostly creamy white to pale yellow flowers. The photos on this page show a second-year plant, just before we abandoned our Pennsylvania garden to head down to Texas. It had obviously not had a chance to develop a mat yet.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
