Digitalis grandiflora (Yellow foxglove)

Daylilies are classic, extremely popular garden plants. They feature long, arching, strappy leaves and long stems of generally 6-petaled flowers, though double flowers are popular as well. Each flower lasts only one day, hence the plant’s common name. Daylilies come in a wide range of colors, from cream and cheery yellow to peach, orange, fiery red, deep burgundy, pink, and purple. Some have contrasting throats and "eye-zones." Daylilies are ideal for a mixed herbaceous perennial border.

'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
