Heuchera plant named ‘Grape Timeless’

Abstract

The new and distinct hybrid of Heuchera plant named Grape Timeless with medium-sized, shallowly lobed, glossy foliage with rounded apices and lobes. Tightly-branched, upright panicles are produced from early summer to early fall for about fourteen weeks displaying large, bright, rosy-pink flowers. The new plant has a compact habit, is vigorous and produces showy, long-flowering, herbaceous, perennial mounds of leaves beginning the season purplish-red and developing a greyed-purple overlay and dark charcoal-purple surrounding the veins, effective as a specimen plant, en masse, or as a container plant in the landscape.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of Heuchera Grape Timeless demonstrate the overall appearance of the plant including the unique traits of a plant in a full sun trial block 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.

(2) FIG. 1 shows a two-year-old plant grown in a container in a partially shaded greenhouse in peak flowering season.

(3) FIG. 2 shows a close-up of a flower panicle with buds and flowers from a two-year-old plant.

DETAILED BOTANICAL DESCRIPTION
