| Claim: |
It is claimed:
1. A new and distinct cultivar of Heuchera plant named `Purple Mountain Majesty`, as illustrated and described. |
| Description: |
Botanical classification/cultivar designation: Heuchera.times.hybrida cultivar Purple Mountain Majesty.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Heuchera plant, botanically known as Heuchera.times.hybrida and hereinafter referred to by the name `Purple Mountain Majesty`.
The new Heuchera is a product of a planned breeding program conducted by the Inventor in Scottdale, Pa. The objective of the breeding program is to create new Heuchera cultivars having good plant vigor, dense and uniform plant habit, and showyand attractive flower and leaf coloration.
The new Heuchera was discovered by the Inventor in a controlled environment in Scottdale, Pa., from seedling progeny from a cross-pollination made by the Inventor in May, 1999, of a proprietary selection of Heuchera.times.hybrida identified ascode number H96-2C, not patented, as the female, or seed, parent with an unnamed selection of Heuchera alba, not patented, as the male, or pollen, parent. The new Heuchera was selected by the Inventor in May, 2000. The selection of this plant was basedon its desirable flower and foliage coloration.
Asexual reproduction of the new Heuchera by cuttings in a controlled environment in Scottdale, Pa., since August, 2000, 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 Purple Mountain Majesty 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 ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Purple Mountain Majesty`. These characteristics in combination distinguish `Purple Mountain Majesty` as a new and distinct cultivar ofHeuchera: 1. Full, densely foliated and uniformly mounded plant habit. 2. Purple and silver-colored foliage. 3. Numerous large white-colored flowers arranged on erect panicles. 4. Excellent garden performance.
Plants of the new Heuchera can be compared to plants of the female parent, the proprietary Heuchera selection identified as H96-2C. In side-by-side comparisons conducted by the Inventor in Scottdale, Pa., plants of the new Heuchera differed fromplants of the female parent selection in the following characteristics: 1. Plants of the new Heuchera were broader than plants of the female parent selection. 2. Plants of the new Heuchera had larger leaves than plants of the female parent selection. 3. Plants of the new Heuchera had taller inflorescences than plants of the female parent selection. 4. Plants of the new Heuchera and the female parent selection differed in flower shape and coloration.
Plants of the new Heuchera can be compared to plants of the male parent, the unnamed selection of Heuchera alba. In side-by-side comparisons conducted by the Inventor in Scottdale, Pa., plants of the new Heuchera differed from plants of the maleparent selection in the following characteristics: 1. Plants of the new Heuchera had purple and silver-colored foliage whereas plants of the male parent selection had green-colored foliage. 2. Plants of the new Heuchera had smaller flowers than plantsof the male parent selection. 3. Plants of the new Heuchera and the male parent selection differed in flower shape and coloration.
Plants of the new Heuchera can be compared to plants of the cultivar Harmonic Convergence, disclosed in U.S. Plant Pat. No. 11,111. In side-by-side comparisons conducted by the Inventor in Scottdale, Pa., plants of the new Heuchera differedfrom plants of the cultivar Harmonic Convergence in the following characteristics: 1. Plants of the new Heuchera had smaller leaves than plants of the cultivar Harmonic Convergence. 2. Plants of the new Heuchera had less silver-colored marbling on theupper surfaces of the leaves than plants of the cultivar Harmonic Convergence. 3. Plants of the new Heuchera had larger flowers than plants of the cultivar Harmonic Convergence. 4. Plants of the new Heuchera and the cultivar Harmonic Convergencediffered in flower form and coloration. 5. Plants of the new Heuchera had shorter and narrower inflorescences than plants of the cultivar Harmonic Convergence.
Plants of the new Heuchera can also be compared to plants of the cultivar Silver Scrolls, disclosed in U.S. Plant Pat. No. 12,066. In side-by-side comparisons conducted by the Inventor in Scottdale, Pa., plants of the new Heuchera differedfrom plants of the cultivar Silver Scrolls in the following characteristics: 1. Plants of the new Heuchera had less silver-colored marbling on the upper surfaces of the leaves than plants of the cultivar Silver Scrolls. 2. Plants of the new Heucherahad larger flowers than plants of the cultivar Silver Scrolls. 3. Plants of the new Heuchera had shorter inflorescences than plants of the cultivar Silver Scrolls.
