Description

RELATED APPLICATIONS

This application is co-pending with U.S. Plant patent application Ser. No. 12/008,311 filed for a cultivar derived from the same parentage entitled Begonia Plant Named ‘Yamance’.

Botanical classification: Begonia hybrida.

Cultivar designation: ‘Yagance’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant of hybrid origin, botanically known as Begonia ‘Yagance’ and will be referred to hereafter by its cultivar name, ‘Yagance’.

The new cultivar was derived from a controlled breeding program conducted by the inventor at his nursery in Congleton, Cheshire, U. K. The overall purpose of the breeding program is to make selections of Begonia plants with compact plant habits suitable for basket and patio containers. ‘Yagance’ was selected as a a single unique plant in 2005 and derived from a cross made between an unnamed proprietary plant of hybrid Begonia as the female parent plant and Begonia boliviensis ‘Yabos’ (U.S. Plant patent application Ser. No. 11/445,753) as the male parent.

Asexual reproduction of the new cultivar was first accomplished by terminal stem cuttings in Congleton, Cheshire, U. K. in 2005 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 ‘Yagance’ as a new and distinct cultivar of Begonia.

• • 1. ‘Yagance’ exhibits single bi-color flowers with pink outer tepals and white inner tepals.
  • 2. ‘Yagance’ readily produces side shoots.
  • 3. ‘Yagance’ exhibits a compact, spreading to pendulous plant habit.
  • 4. ‘Yagance’ has a vigorous growth habit.

In comparison, the unnamed female parent of ‘Yagance’ differs from ‘Yagance’ in having double flowers and the male parent, ‘Yabos’, differs from ‘Yagance’ in having red-orange flowers. ‘Yamance’, its sibling selection, differs from ‘Yagance’ in having apricot pink flowers. ‘Yagance’ can also be compared to ‘Bonfire’ (U.S. Plant No. 15,108), which differs from ‘Yagance’ in having flowers that are red and not bi-color.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Begonia. The photographs were taken in September of a plant approximately 6 months in age as grown in a two-liter container in Swavesey, Campbridgeshire, U.K.

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

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Yagance’. The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description 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 6 months in age as grown in two-liter containers under greenhouse conditions with ambient light in Congleton, Cheshire, U.
