Alternanthera plant named ‘Brazilian Red’
A new and distinct Alternanthera plant cultivar is disclosed, characterized by an upright, freely branching growth habit, bright pink and dark purple two-toned foliage, small, narrow leaves and small, round white flowers that last 3 months or more during the fall.

Latin name of the genus and species; Alternanthera dentata.
Variety denomination: ‘Brazilian Red’.
BACKGROUND OF THE INVENTION
The new cultivar is a product of a whole plant natural mutation. ‘Brazilian Red’ was discovered as a single plant by Lucilene Anatriello in a greenhouse of Alternanthera dentata plants on Sep. 10, 2005 in São José do Rio Preto, Brazil. The breeder selected the natural mutation of Alternanthera dentata for the best color and shape of the plant.
Asexual reproduction of the new cultivar ‘Brazilian Red’ by vegetative cuttings was performed in São José do Rio Preto, Brazil and Oxnard, Calif., and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘Brazilian Red’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘Brazilian Red.’ These characteristics in combination distinguish ‘Brazilian Red’ as a new and distinct Alternanthera cultivar:
- 1. Upright, freely branching and vigorous growth habit;
- 2. Bright pink and dark purple two-toned foliage;
- 3. Small, narrow leaves; and
- 4. Small, round white flowers that last 3 months or more during the fall.
Plants of the new cultivar ‘Brazilian Red’ are similar to plants of the parent variety, Alternanthera dentata, in most horticultural characteristics, however, plants of the new cultivar ‘Brazilian Red’ differ primarily from the parent in foliage coloration. ‘Brazilian Red’ was selected for its very brightly colored foliage of bright pink and purple coloration.
In comparison to the commercially available variety ‘Grenadine’ (U.S. Plant Pat. No. 16,442), ‘Brazilian Red’ is from the species A. dentata, not the species A. ficoidea. Also, the new cultivar ‘Brazilian Red’ is taller and has a wider plant spread. Additionally, ‘Brazilian Red’ has a shorter internode length. Further, the new cultivar ‘Brazilian Red’ has smaller leaves and a different leaf shape. Finally, ‘Brazilian Red’ has bright pink interveinal areas and dark purple veinal areas with pink venation, while the ‘Grenadine’ foliage has darker brown interveinal areas and pink veinal areas.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in the drawing illustrates in full color a typical plant of ‘Brazilian Red’ grown in a 2 gallon container. One cutting was used in the pot. The colors are as nearly true as is reasonably possible in a color representative of this type.
