Botanical classification/cultivar designation: Alternanthera ficoidea cultivar Partytime.


The present Invention relates to a new and distinct cultivar of Alternanthera plant, botanically known as Alternanthera ficoidea, and hereinafter referred to by the cultivar name Partytime.

The new Alternanthera was discovered in June, 2000, by the Inventor in a controlled environment in Atlanta, Ga., as a naturally-occurring branch mutation of an unidentified selection of Alternanthera ficoidea, not patented. The cultivar Partytime was selected by the Inventor on the basis of its unique foliage coloration.

Asexual reproduction of the new cultivar by vegetative cuttings taken in Atlanta, Ga., since August, 2000, has shown that the unique features of this new Alternanthera are stable and reproduced true to type in successive generations.


Plants of the cultivar Partytime 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 ‘Partytime’. These characteristics in combination distinguish ‘Partytime’ as a new and distinct cultivar:

1. Upright and rounded plant habit.

2. Freely branching habit; bushy and dense growth habit.

3. Green, creamy white and red purple-colored leaves.

Plants of the new Alternanthera differ from plants of the parent selection primarily in foliage coloration as plants of the parent selection had green and burgundy-colored foliage. Plants of the new Alternanthera differ primarily from plants of known cultivars of Alternanthera ficoidea in leaf coloration.


The accompanying colored photographs illustrate 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 photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Alternanthera.

The photograph at the top of the sheet is a close-up view of a typical plant of ‘Partytime’.

The photograph at the bottom of the sheet comprises a close-up view of typical leaves of a plant of ‘Partytime’.


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 photographs and in the following description were grown in Atlanta, Ga. in one-gallon containers in a polyethylene-covered greenhouse and under conditions which closely approximate commercial production conditions. In the greenhouse, day temperatures ranged from 75 to 85° F. and night temperatures ranged from 60 to 75° F. Plants were about six months old when the photographs and description were taken. The photographs and description were taken during the early summer.
