Penstemon digitalis 'Husker Red' Penstemon digitalis 'Husker Red'
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

'Husker Red' is one of the few penstemons that does well in wet winters and hot, humid summers. Ruby-toned leaves appear in spring, followed in late spring and early summer by 3-foot-high stems adorned by panicles of white blooms.  The flowers attract bees, hummingbirds, and butterflies, but the plants are not magnets for deer or rabbits. In autumn and winter, songbirds feast on the seed. For a stunning display, plant 'Husker Red' in groups. -Chris Kelley, Regional Picks: Midwest, Fine Gardening issue #120

Podophyllum peltatum Podophyllum peltatum

Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

In spring, white or pale pink waxy flowers are mostly hidden under the leaves. The greenish "mayapple" follows and is often eaten by wildlife. When fully ripe, the fruits may be used to make preserves or jellies, but they are toxic when unripe. Leaves and roots are poisonous. Plants often go dormant in the summer. Grow in a woodland garden.
