Growing Daylilies: A Complete Beginner's Guide

Introduction to Daylilies

Daylilies (Hemerocallis) are among the most beloved and easy-to-grow perennials in the world. Their name comes from Greek—hemera (day) and kallos (beauty)—because each individual flower typically lasts just one day. But don't let that fool you: a single plant can produce dozens to hundreds of blooms over an extended season, creating continuous waves of color.

Originally from Asia where they've been cultivated for over 4,000 years, daylilies have been transformed by modern breeding into an astonishing rainbow of colors, patterns, and forms. With over 100,000 registered cultivars and more introduced every year, there's truly a daylily for every garden and gardener.

Why Grow Daylilies?

Unmatched Reliability

Daylilies are famously tough. They tolerate drought, heat, humidity, poor soil, and neglect while still producing beautiful flowers.

Incredible Variety

From miniatures under 12 inches to giants over 4 feet, in every color except true blue and pure white, with patterns including bicolors, edges, eyes, and watermarks.

Long Bloom Season

While individual flowers last only a day, the succession of buds extends the show for weeks. Reblooming varieties can flower from spring through frost.

Low Maintenance

Once established, daylilies need minimal care—no staking, little pest or disease pressure, and only occasional division.

Versatility

Perfect for borders, massed plantings, slopes, containers, and even ground cover applications.

Wildlife Value

Daylilies attract hummingbirds and butterflies, though they're also deer-resistant in many gardens.
