Daylily (Hemerocallis)

Quick facts and care essentials

Bulbs

• Tuberous root
• All zones
• Full sun or light shade
• Regular watering during growing season

Tough and trouble free, daylilies are familiar components of perennial borders. Growing in large clumps, the arching, sword-shaped leaves may be evergreen, semievergreen, or deciduous, depending on the type.

Modern hybrids grow 1 to 6 feet tall and bloom in spring and summer, producing flowers that vary from 3 to 8 inches wide and come in a wide range of colors. Each flower lasts just one day (hence the common name), but buds open on successive days to prolong the display.

Set out the tuberous roots in fall or early spring, planting them 1/2 to 1 inch deep and 2 to 2 1/2 feet apart. Set out plants from containers at any time from early spring through midautumn.
