Abstract

A new and distinct cultivar of Begonia plant named ‘Gum Drop Rose’, characterized by its compact, upright and uniform plant habit; freely branching growth habit, dense and bushy growth habit; green-colored leaves; freely flowering habit with numerous flowers per plant; and small mostly double flowers that are dark pink in color and held above and beyond the foliage.

Description

Botanical classification/cultivar designation: Begonia semperflorens cultivar Gum Drop Rose.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia semperflorens, and hereinafter referred to by the name ‘Gum Drop Rose’.
The new Begonia is a product of a planned breeding program conducted by the Inventor in Fukuoka, Kyushu, Japan. The objective of the breeding program was to develop new Begonia cultivars with double flowers and attractive leaf and flower coloration.
The new Begonia originated from a cross made by the Inventor in 1995, of the Begonia semperflorens cultivar Double Pink, not patented, as the female, or seed parent, with the Begonia semperflorens cultivar Bazel, not patented, as the male, or pollen parent. The cultivar Gum Drop Rose was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Fukuoka, Kyushu, Japan.
Asexual reproduction of the new Begonia by cuttings taken in a controlled environment in Fukuoka, Kyushu, Japan since 1999 has shown that the unique features of this new Begonia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘Gum Drop Rose’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Gum Drop Rose’. These characteristics in combination distinguish ‘Gum Drop Rose’ as a new and distinct Begonia cultivar:
1. Compact, upright and uniform plant habit.
2. Freely branching growth habit, dense and bushy growth habit.
3. Green-colored leaves.
4. Freely flowering habit, numerous flowers per plant.
5. Small mostly double flowers that are dark pink in color and held above and beyond the foliage.
Plants of the new Begonia differ from plants of the female parent, the cultivar Double Pink, in leaf and flower coloration as plants of the cultivar Double Pink have bronze-colored leaves and pink-colored flowers. Plants of the new Begonia differ from plants of the male parent, the cultivar Bazel, in flower form as plants of the cultivar Bazel have single flowers.
The new Begonia differs from plants of the Begonia semperflorens cultivars Gum Drop Mandarin, disclosed in U.S. Plant patent application Ser. No. 10/684,563, Gum Drop Pink, disclosed in U.S. Plant patent application Ser. No. 10/684,531, and Gum Drop Rose, disclosed in U.S. Plant patent application Ser. No. 10/684,525, primarily in flower coloration.
The new Begonia can also be compared to the Begonia semperflorens cultivar Queen Pink, not patented. However, in side-by-side comparisons conducted in Fukuoka, Kyushu, Japan, plants of the new Begonia differed from plants of the cultivar Queen Pink in the following characteristics:
1. Plants of the new Begonia had smaller leaves than plants of the cultivar Queen Pink.
2. Plants of the new Begonia had smaller flowers than plants of the cultivar Queen Pink.
3. Flowers of plants of the new Begonia were more often double than plants of the cultivar Queen Pink.
4. Flowers of plants of the new Begonia did not produce pollen whereas flowers of plants of the cultivar Queen Pink produced pollen.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Begonia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description accurately describe the colors of the new Begonia.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Gum Drop Rose’.
The photograph at the bottom of the sheet is a close-up view of typical flowers and leaves of ‘Gum Drop Rose’.
DETAILED BOTANICAL DESCRIPTION
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.
