Culture
Easily grown in average, dry to medium, well-drained soils in full sun. Plants have some tolerance for drought, summer heat and humidity. Avoid wet, poorly-drained soils. Remove spent flowering racemes to prolong bloom. Plants may be cut back to basal foliage after flowering to improve appearance of the planting. Plants in cold winter climates often benefit from a loose winter mulch.
Noteworthy Characteristics
Penstemon is a genus of about 250 species of herbaceous perennials and sub-shrubs which are primarily native to the continental U.S., Canada, Mexico and Guatemala in a variety of habitats ranging from desert to plains to alpine slopes. A large number of hybrids have been developed over the years, but most are of unclear parentage.
Genus name comes from the Greek words penta meaning five and stemon meaning stamen in reference to each flower having five stamens (four are fertile and one is sterile).
Penstemons are sometimes commonly called beardtongues because the unusual sterile stamen contained in each flower has a tuft of small hairs.
‘Pensham Eleanor Young’ is a clump-forming penstemon that typically grows 24-30" tall. It is noted for its large, two-lipped, trumpet-shaped, dark crimson flowers with white throats. Flowers bloom from early summer to fall in loose upright terminal panicles atop erect stems clad with lanceolate rich green stem leaves. 'Pensham Eleanor Young' was developed and introduced by Edward Wilson of Pershore Plant Raisers in the village of Pensham, Worcestershire, England.
Problems
Root rot can occur in wet, poorly-drained soils. Leaf spots, rusts, powdery mildew and Southern blight may also occur. Slugs and snails may chew on the foliage. Watch for spider mites. Deer tend to avoid this plant.
Uses
Sunny areas of borders, rock gardens, cottage gardens and open woodland areas.
May be grown as an annual.
