Penstemon rydbergii

Rydberg's Penstemon (aka Meadow Beardtongue) is one of those wildflowers that takes center stage. The vegetation emerges in the spring as a bright green basal rosette followed by an upright stem generally standing up to two feet. By summer, countless striking blueish-purple, bearded flowers adorn all sides of the stem in dynamic whorls, like floral fireworks. It is a nutrient-rich source of food to hummingbirds, song birds, bumblebees, and butterflies and an excellent choice for pollinator gardens, moist meadowscapes and sunny raingardens.

  • Size at maturity: 1’-2’ tall, 3’ wide

Gardening with Rydberg’s Penstemon: Ryberg Penstemon is long-lived and one of the most showy wildflowers for Pacific Northwest habitat gardens. It prefers full sun, but can tolerate some shade, and can handle a variety of soils. It tends to grow in moist meadows and streambanks, so be sure to plant it in a perennially moist location. Consider planting several (generally clumps of three to five spaced a couple feet apart) in a meadowscape with native grasses and other companion perennials such as columbine, lilies, western buttercup, triteleia and violets.
