Abstract

A new cultivar of hybrid Begonia named ‘YASPRINK’, characterized by its large single pink flowers with a high degree of forward and horizontal facing flowers and its compact well-branched habit without cane production in its first year of growth.

Description

Botanical classification: Begonia hybrid.

Cultivar designation: ‘YASPRINK’.

RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent applications filed for cultivars derived from the same breeding program entitled Begonia Plant named ‘YASPWHIT’ (U.S. Plant Ser. No. 13/066,386), Begonia Plant Named ‘YADEV’ (U.S. Plant Pat. No. 21,852), Plant Named ‘YAMINA’ (U.S. Plant Pat. No. 22,462), Begonia Plant Named ‘YAMOUR’ (U.S. Plant Pat. No. 22,788), and Begonia Plant Named ‘YASPED’ (U.S. Plant Pat. No. 22,412) and related to a cultivar from the same breeding program with a U.S. Patent, Begonia Plant Named ‘YABOS’ (U.S. Plant Pat. No. 20,093).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically an interspecific hybrid that includes Begonia boliviensis hybrids in its parentage. The new cultivar is known as Begonia ‘YASPRINK’ and will be referred to hereafter by its cultivar name, ‘YASPRINK’.

The new cultivar was derived from a controlled breeding program conducted by the inventor at his nursery in Congleton, Cheshire, United Kingdom. The overall purpose of the breeding program is to make selections of Begonia plants to produce good basket and patio plants. ‘YASPRINK’ was selected in the Inventor's greenhouse in 2008 as a single unique plant from amongst the seedlings derived from a cross made in 2007 between an unnamed Begonia plants of hybrid origin from the Inventor's breeding program as the female and male parents.

Asexual reproduction of the new cultivar was first accomplished by stem tip cuttings in Congleton, Cheshire, United Kingdom in 2008 by the Inventor. It has been determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar, which in combination distinguish ‘YASPRINK’ as a new and distinct cultivar of Begonia.

- 1. ‘YASPRINK’ exhibits large, single pink flowers.
- 2. ‘YASPRINK’ exhibits flowers that have a high degree of forward and horizontal facing flowers.
- 3. ‘YASPRINK’ exhibits a compact and well-branched habit without cane production in its first year of growth.

‘YASPRINK’ is particular unique in having the flower form of Begonia boliviensis combined with a habit that lacks cane production in its first year of growth and in having a more compact habit than is typical of plants of Begonia boliviensis. The female parent differs from ‘YASPWHIT’ in having white flowers, a lower degree of forward and horizontal facing flowers and in having a less compact habit with less branching. The male parent is similar to ‘YASPRINK’ in having pink flowers but differs from ‘YASPRINK’ in having a less compact and branched habit. ‘YASPRINK’ can be most closely compared to cultivars from the same breeding program; ‘YADEV’, ‘YABOS’, ‘YASPED’, and ‘YAMINA’, which differ from ‘YASPRINK’ in having flowers that are red in color, ‘YABON’, which differs from ‘YASPRINK’ in having semi-double flowers that are yellow in color and ‘YASPWHIT’, which differs from ‘YASPRINK’ in having white flowers flushed with pink. ‘YAMINA’ also differs from ‘YASPRINK’ in having much larger flowers, larger leaves, and a groundcover type plant habit and ‘YADEV’ also differs from ‘YASPRINK’ in having leaves that are dark olive green in color. ‘YASPRINK’ can also be compared to ‘Bonfire’ (U.S. Plant Pat. No. 15,108), which differs from ‘YASPRINK’ in often having un-branched canes in its first year of growth, in having flowers that are orange-red in color, smaller in size, and on drooping stems and in having a plant habit that has fewer basal or secondary branches.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Begonia. The photographs were taken of a plant approximately three months in age as grown in a 15-cm container under greenhouse conditions under ambient light in Liss, Hampshire, United Kingdom.

The photograph in FIG. 1 provides a side view of ‘YASPRINK’ in bloom.

The photograph in FIG. 2 provides a close-up view of the female flowers of ‘YASPRINK’.

The photograph in FIG. 3 provides a close-up view of the male flowers of ‘YASPRINK’.

The photograph in FIG. 4 provides a close-up view of the leaves of ‘YASPRINK’. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Begonia.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of plants of the new cultivar approximately three months in age as grown in 15-cm containers under greenhouse conditions with ambient light in Liss, Hampshire, United Kingdom. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
