Rapidly Spreading Ground Cover

A giant bloom size for this species, it displays more vigorous flowering with huskier blooms. This charmer still maintains the stature of Dwarf Crested Iris. Soft lavender-blue 3” wide flowers with golden crests provide a carpet of color each spring. Does best in some shade. Iris Powder Blue Giant will readily spread by branching rhizomes to form colonies of small sword-shaped leaves after the mid-to-late spring blooms have faded. Our plant spacing recommendations are based on how quickly groundcovers will spread in their first season of growth.

Iris General Information

An excellent plant for early spring bloom in a shaded area of the rock garden, perennial border or woodland garden. Foliage forms a nice ground cover for woodland areas. May also be used as a seasonal ground cover or edger.

Iris Plant Care

Iris cristata are best grown in organically rich, well-drained soils in part shade. Will tolerate close to full shade. Soil must be kept consistently moist if grown in full sun. A nice ground cover on well-drained banks or slopes. Grows from rhizomes and can be divided after flowering is done with a sharp spade or pull apart entangled rhizomes.

All potted plant material is restricted from shipping to Idaho

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!

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.
