Hosta
Electrify the shady corners of your landscape with hostas. Colorful and reliable, hostas vary from 4-inch-tall dwarfs to 4-foot-tall giants. Although prized for their beautiful blue, green, chartreuse, or bicolor foliage, hostas also send up lovely spikes of pink, lavender, or white flowers that attract hummingbirds and butterflies. These perennial flowers for shade are almost impossible to kill, but slugs, snails, and deer will feast on them, so be prepared to do battle if these pests are common in your region. Hostas grow well in containers, too, so be sure to pot up some of your favorites with shade-loving annuals, such as impatiens and begonias.
