The present application is co-pending with the following related applications:
- Alternanthera Plant Named ‘Cognac’.
- Alternanthera Plant Named ‘Creme de Menthe’.
The present Invention relates to a new and distinct cultivar of Alternanthera plant, botanically known as Alternanthera ficoidea, and hereinafter referred to by the name ‘Grenadine’.
The new Alternanthera was discovered in December, 2002, by the Inventor in a controlled environment in Chamblee, Ga., as a naturally-occurring branch mutation of the Alternanthera ficoidea cultivar Partytime, disclosed in U.S. Plant Pat. No. 14,789. The cultivar Grenadine was selected by the Inventor on the basis of its unique foliage coloration.
Asexual reproduction of the new cultivar by vegetative cuttings in Chamblee, Ga., since January, 2003, has shown that the unique features of this new Alternanthera are stable and reproduced true to type in successive generations.SUMMARY OF THE INVENTION
Plants of the cultivar Grenadine have 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 ‘Grenadine’. These characteristics in combination distinguish ‘Grenadine’ as a new and distinct cultivar:
- 1. Upright and outwardly spreading plant habit.
- 2. Freely branching habit; bushy and dense growth habit.
- 3. Brown and red purple bi-colored leaves.
Plants of the new Alternanthera can be compared to plants of the parent, the cultivar Partytime. In side-by-side comparisons conducted in Chamblee, Ga., plants of the new Alternanthera differed from plants of the cultivar Partytime primarily in foliage coloration as plants of the cultivar Partytime had green, creamy white and red purple-colored leaves.
Plants of the new Alternanthera can also be compared to plants of the cultivars Cognac, disclosed in U.S. Plant patent application Ser. No. 11/022,012, and Creme de Menthe, disclosed in U.S. Plant Patent application Ser. No. 11/022,001. In side-by-side comparisons conducted in Chamblee, Ga., plants of the new Alternanthera differed from plants of the cultivars Cognac and Creme de Menthe primarily in leaf coloration as plants of the cultivar Cognac had dark purplish brown-colored leaves and plants of the cultivar Creme de Menthe had green and pale yellow bi-colored leaves.
The accompanying colored photograph illustrates the unique appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Alternanthera. The photograph is a top perspective view of a typical plants of ‘Grenadine’ grown in a container.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the aforementioned photograph and in the following description were grown in Atlanta, Ga. during the summer in an outdoor nursery and under conditions which closely approximate commercial production conditions. During the production of the plants, day temperatures ranged from 80 to 90° F. and night temperatures ranged from 60 to 75° F. Plants were about four months old when the photograph and description were taken.
