Abstract

A new and distinct cultivar of Heuchera plant named ‘Prince of Silver’, characterized by its uniformly mounded plant habit; silvery gray-colored upper leaf surfaces silvery gray with contrasting dark greenish brown-colored venation; dark purple-colored lower leaf surfaces; pink-colored flowers arranged on upright racemes; and faintly fragrant flowers.

Description

Botanical classification/cultivar designation: Heuchera sp. cultivar Prince of Silver.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Heuchera plant, botanically known as Heuchera sp. and hereinafter referred to by the name ‘Prince of Silver’.
The new Heuchera is a product of a planned breeding program conducted by the Inventor in Lisserbroek, The Netherlands. The objective of the breeding program is to create new Heuchera cultivars having attractive leaf and flower coloration.
The new Heuchera was discovered by the Inventor in a controlled environment in Lisserbroek, The Netherlands, from seedling progeny from a cross-pollination made by the Inventor of two unidentified Heuchera selections, not patented. The new Heuchera was selected by the Inventor on the basis of its unique leaf and flower coloration.
Asexual reproduction of the new Heuchera by cuttings taken in a controlled environment in Lisserbroek, The Netherlands, since 2001, has shown that the unique features of this new Heuchera are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Prince of Silver has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Prince of Silver’. These characteristics in combination distinguish ‘Prince of Silver’ as a new and distinct cultivar of Heuchera:
1. Uniformly mounded plant habit.
2. Silvery gray-colored upper leaf surfaces with contrasting dark greenish brown-colored venation.
3. Dark purple-colored lower leaf surfaces.
4. Pink-colored flowers arranged on upright racemes.
5. Faintly fragrant flowers.
Compared to plants of the parent selections and other known selections and cultivars of Heuchera, plants of the new Heuchera differ in leaf and flower coloration.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Heuchera, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Heuchera.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Prince of Silver’.
The photograph at the top of the second sheet is a close-up view of a typical flowering raceme of ‘Prince of Silver’.
The photograph at the bottom of the second sheet is a close-up view of typical leaves of ‘Prince of Silver’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following description describe plants grown in Boskoop, The Netherlands during the late spring and early summer in an unshaded outdoor nursery and under cultural conditions which approximate commercial practice. During the period of time the photographs and description were taken, day temperatures ranged from 9 to 21° C. and night temperatures ranged from 3 to 11° C. Plants were grown as single plants in two-liter containers and were about two years old when the photographs and description were taken.
