Description

Penstemon calycosus is a showy wildflower that grows to a height of 3'. It produces terminal clusters of pinkish, snapdragon-like flowers. These appear on singular, rigid stems that are divided at their very top. The flowers give way to small seed capsules.

Cultivation

Easily grown in in full to art-sun. Moist, rich to average, well drained soil. It has a month-long bloom period, from May to July. Flowering stalks die down by mid summer, as new basal leaves appear. These will persist through winter. The plants develop taproots, making them moderately drought resistant. Self seeds readily, without being aggressive or invasive. Zones 4-6

Propagation

Easy to propagate from seed. Can be propagated by division in early spring, taking care not to damages the taproots.

Additional Notes

Penstemon calycosus is an attractive, underutilized wildflower. It can be a wonderful addition to any cottage garden, perennial flower border or rock garden.
