Daylilies
One of the easiest perennials to grow, daylilies (Hemerocallis) provide colorful flowers and when not in bloom the plant is still attractive because of the grass like foliage.
Daylilies come in many sizes from around 10 inches to around 40 inches tall with most being in the 2 to 3 foot range. Daylilies are available in almost any color except blue. Daylily flowers are basically trumpet shaped, but modern hybrids produce blooms in a variety of shapes and forms some with double petals or ruffled petals or even spider shaped petals. Many daylilies will have a central eye that is a contrasting color. Some have blooms edged in a different color.
I have daylilies and daffodils planted on each side of my front walkway. The daffodils bloom in early spring before the daylilies start new growth. The daylilies new growth starts and by the time the daffodils are nothing but dying foliage the daylilies have nice lush foliage that hides the yellowing daffodil foliage.
Daylilies are a gardeners dream plant. Daylilies have beautiful blooms, good looking foliage, they are easy to maintain and muliply quickly. What more could you ask for?
You can find daylilies here at Southern-Gardening and at Jackson & Perkins, as well as some of these online nurseries.
