Heuchera plant named ‘Wildberry’

Abstract

The new and distinct hybrid of Heuchera plant named Wildberry with many large, rounded-palmate, shallowly dissected foliage and large, dense, mounded habit. The leaf blades are deep to strong purplish-red with darker greyed purple surrounding veins. Branched panicles produce complimentary strong purplish-red calyces and flower effect for about five weeks beginning mid-summer. The new plant is vigorous and produces large clumps with many large leaves.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of Wildberry demonstrate the overall appearance of the plant including the unique traits of a container-grown plant in a greenhouse in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.
