SEASONAL CARE

Spring Care:

Summer Care:

To keep penstemon that have finely textured or matted evergreen foliage looking their best, you'll want to deadhead them. Shear off the fading flowering spikes just as the plant is going out of flower. Gently bunch the flower spikes together with one hand

Fall Care:

Allow some of the plants to set seed (don't deadhead all of the flower spikes). In colder areas, a layer of dry mulch should be applied after the first hard freeze.

Winter Care:

Leave some stems for frost protection and mulch with straw in winter, if necessary.

Long Term Care:

Plant high, leaving the top of the rootball just above the surrounding soil to avoid burying the crown of the plant. They need ?elbow room,? maximum sun, heat and don?t like to be crowded by other plants.

Diseases:

The OSU Plant Clinic has found Phytophthora spp., Rhizoctonia spp., and Fusarium spp. associated with root rots of Penstemon spp. grown in Oregon. (https://pnwhandbooks.org/plantdisease/host-and-disease-descriptions?title=Penstemon-Root+Rot)
