Hemerocallis General Information

Rugged and adaptable, Daylilies are quick to establish and require little care. Carefree, pest resistant and free of Hemerocallis rust disease. They even grow under Black Walnut trees and along salted driveways. Outstanding! Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Hemerocallis Plant Care

Tough, cold and drought tolerant, long lived plants. Can be divided most any time of year. Division usually needed every 3-4 years for best performance.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

100% Guarantee

We offer a 100% guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
