Begonia plant named ‘YABOS’

Abstract

A new cultivar of Begonia, Begonia boliviensis ‘Yabos’, characterized by its compact, freely branched, pendulant plant habit combined with red-orange flowers and ease of propagation.

Description

Botanical classification: Begonia boliviensis.

Cultivar designation: ‘Yabos’.

BACKGROUND OF THE INVENTION

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

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 container use combined with superior flower performance and productive stock plants for propagation. ‘Yabos’ was selected as a whole plant in 2004 and derived from a cross made between unnamed proprietary plants of Begonia boliviensis.

‘Yabos’ was selected as unique for its compact pendulous plant habit, its abundant production of side shoots and its red-orange flowers. ‘Yabos’ differs from its closest comparison cultivar, ‘Bonfire’ (U.S. Plant Pat. No. 15,108) in having a flatter, more pendulous plant habit and flowers that are more red in color.

Asexual reproduction of the new cultivar was first accomplished by terminal stem cuttings in Congleton, Cheshire, U. K. in 2004 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 ‘Yabos’ as a new and distinct cultivar of Begonia.

• • 1. ‘Yabos’ exhibits a compact, pendulous plant habit.
  • 2. ‘Yabos’ readily produces side shoots.
  • 3. ‘Yabos’ exhibits red-orange flowers.
  • 4. ‘Yabos’ produces productive stock plants for propagation.

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 July of a plant approximately 17 weeks in age as grown in a one-liter container in Swavesey, Campbridgeshire, U. K.

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

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Yabos’. 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 17 weeks in age as grown in one liter containers under greenhouse conditions with ambient light in Congleton, Cheshire, U. K. 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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
