They prefer well-drained soil, and young plants need adequate water to thrive. Differing daylily petal and flower shapes also add interest to the landscape. You can find daylily petals that are wide, overlapping, crinkled, frilled or ruffled. Some flower shapes include trumpet, cup and bell. Daylilies can be grouped into three categories by their foliage.
Dormant types lose their foliage after the first frost.
The plant dies to the ground each winter and produces new foliage in the spring. Semi-evergreen types may die back to the ground in a very cold winter or annually in the Northern half of Alabama but will grow new leaves in the spring. Evergreen types retain their foliage year-round. Daylilies can fit into many spots in the landscape. Compact, evergreen types are effective as ground covers.
