Abstract
A new and distinct cultivar of Heuchera plant named ‘Rex Purple’, characterized by its uniformly mounded plant habit; densely foliated and bushy appearance; greyed purple-colored leaves; long flowering period; numerous inflorescences with sterile white and red purple-colored flowers; resistance to Powdery Mildew; and good garden performance.
Description
Botanical designation: Heuchera hybrid X Heuchera villosa.
Cultivar denomination: ‘REX PURPLE’.
The present invention relates to a new and distinct Heuchera plant of Heuchera, botanically known as Heuchera hybrid X Heuchera villosa and hereinafter referred to by the name ‘Rex Purple’.
The objective of the breeding program is to create new compact Heuchera plants with attractive leaf colors, less sensitivity to Powdery Mildew and good garden performance.
The new Heuchera plant originated from a cross-pollination in July, 2014 in Zuidwolde, The Netherlands of Heuchera hybrid ‘Mars’, not patented, as the female, or seed, parent with a proprietary selection of Heuchera villosa identified as code number 083-C047, not patented, as the male, or pollen, parent. The new Heuchera plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Zuidwolde, The Netherlands in June, 2015.
Asexual reproduction of the new Heuchera plant by in vitro meristem culture in a controlled environment in Zuidwolde, The Netherlands since March, 2017 has shown that the unique features of this new Heuchera plant are stable and reproduced true to type in successive generations.
The new Heuchera plant has not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Rex Purple’. These characteristics in combination distinguish ‘Rex Purple’ as a new and distinct Heuchera plant:
-
- 1. Uniformly mounded plant habit.
- 2. Densely foliated and bushy appearance.
- 3. Greyed purple-colored leaves.
- 4. Long flowering period.
- 5. Numerous inflorescences with sterile white and red purple-colored flowers.
- 6. Resistance to Powdery Mildew.
- 7. Good garden performance.
Plants of the new Heuchera differ from plants of the female parent, ‘Mars’, in leaf color as plants of ‘Mars’ have greyed green-colored leaves. In addition, plants of the new Heuchera have larger leaves than plants of ‘Mars’.
Plants of the new Heuchera differ from plants of the male parent selection in leaf color as plants of the male parent selection have more grey-colored leaves. In addition, plants of the new Heuchera have smaller leaves than plants of the male parent selection.
Plants of the new Heuchera can be compared to plants of Heuchera hybrid ‘Shanghai’, disclosed in U.S. Plant Pat. No. 21,859. In side-by-side comparisons, plants of the new Heuchera differ primarily from plants of ‘Shanghai’ in plant size as plants of the new Heuchera are taller than plants of ‘Shanghai’. In addition, plants of the new Heuchera have larger leaves than plants of ‘Shanghai’.
The accompanying colored photographs illustrates the overall appearance of the new Heuchera plant 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 plant.
The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Rex Purple’ grown in a container.
The photograph at the top of the second sheet is a close-up view of typical inflorescences of ‘Rex Purple’.
The photograph at the bottom of the second sheet is a close-up view of typical leaves of ‘Rex Purple’.
The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 2-liter containers in an outdoor nursery in Wieringerwerf, The Netherlands and under cultural practices typical of commercial Heuchera production. During the production of the plants, day temperatures ranged from 18° C. to 30° C. and night temperatures ranged from 6° C. to 18° C. Plants were one year old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
