Abstract: A new and distinct cultivar of Begonia plant named `Gum Drop Pink`, 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 pink in color and held above and beyond the foliage.
Claim: It is claimed:

1. A new and distinct cultivar of Begonia plant named `Gum Drop Pink`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Begonia semperflorens cultivar Gum Drop Pink.

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 Pink`.

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 flowercoloration.

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, orpollen parent. The cultivar Gum Drop Pink 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 Pink` 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 ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Gum Drop Pink`. These characteristics in combination distinguish `Gum Drop Pink` 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 pink in color and held aboveand beyond the foliage.

Plants of the new Begonia differ from plants of the female parent, the cultivar Double Pink, in leaf coloration as plants of the cultivar Double Pink have bronze-colored leaves. 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 Red, disclosed in U.S. Plant patent application Ser. No. 10/684,525, andGum Drop Rose, disclosed in U.S. Plant patent application Ser. No. 10/684,517, 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 QueenPink in the following characteristics: 1. Plants of the new Begonia has 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 newBegonia 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 slightlyfrom the color values cited in the detailed botanical description which 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 Pink`.

The photograph at the bottom of the sheet is a close-up view of typical flowers and leaves of `Gum Drop Pink`.

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.
