ABSTRACT:
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as
Mandevilla hybrid
, and hereinafter referred to by the cultivar name Red Velvet.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Hawthorne, Fla. The objective of the breeding program was to develop new vigorous Mandevilla cultivars with attractive and unique flower colors.
The new cultivar originated from a self-pollination of the cultivar PSJAM LP1, disclosed in U.S. Plant Pat. No. 10,611, made in Hawthorne, Fla., in November, 1996. The new cultivar was discovered and selected by the Inventor as a flowering plant within the progeny from this self-pollination in a controlled environment in Hawthorne, Fla., in 1999. The new cultivar was selected on the basis of its large dark red flowers and vigorous growth habit.
Asexual reproduction of the new cultivar by terminal cuttings taken in Hawthorne, Fla., since April, 1999, has shown that the unique features of this new Mandevilla are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Red Velvet have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, humidity, water status and/or fertilizer rate and type without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Red Velvet’. These characteristics in combination distinguish ‘Red Velvet’ as a new and distinct cultivar:
1. Vigorous growth habit and rapid growth rate.
2. Large, glossy, dark green leaves.
3. Large flowers that are dark pink in color when temperatures are less than 29° C. and intensify to dark red in color when temperatures are greater than 29° C.
4. Red flower throat color.
5. Tolerance to low and high temperatures.
Plants of the new Mandevilla differ primarily from plants of the parent cultivar PSJAM LP1 in flower color as flowers of plants of the cultivar PSJAM LP1 are light pink in color.
Plants of the new Mandevilla can be compared to plants of the cultivar PSJAM DP1, disclosed in U.S. Plant Pat. No. 10,413. In side-by-side comparisons conducted by the Inventor in Hawthorne, Fla., plants of the new Mandevilla were more vigorous, grew faster and had darker colored flowers than plants of the cultivar PSJAM DP1.
Plants of the new Mandevilla can be compared to plants of the cultivar Ruby Star, disclosed in U.S. Plant Pat. No. 8,842. In side-by-side comparisons conducted by the Inventor in Hawthorne, Fla., plants of the new Mandevilla were much faster growing, produced three to four times as many flowers per plant, and had larger flowers than plants of the cultivar Ruby Star. In addition, flowers of the new Mandevilla have overlapping petals whereas flowers of the cultivar Ruby Star do not have overlapping petals.
Plants of the new Mandevilla can be compared to plants of the cultivar Alice DuPont, not patented. In side-by-side comparisons conducted by the Inventor in Hawthorne, Fla., plants of the new Mandevilla were much faster growing, produced three to four times as many flowers per plant, and had larger and darker colored flowers than plants of the cultivar Alice DuPont.
