plant named ‘BROTHGLOW’

Abstract

A new cultivar of tuberous Begonia, Begonia ‘BROTHGLOW’, characterized by its upright growth habit with good basal branching, its single male flowers that are apricot in color, and its evenly formed leaves that are dark olive green-bronze in color.

Description

Botanical classification: Begonia hybrid.

Cultivar designation: ‘BROTHGLOW’.

RELATED APPLICATIONS

This application is related to an application filed for a cultivar derived from the same breeding program entitled 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 tuberous Begonia plant, botanically of hybrid origin and known as Begonia ‘BROTHGLOW’ and will be referred to hereafter by its cultivar name, ‘BROTHGLOW’.

The new cultivar was derived from a controlled breeding program conducted by the inventors at a 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. ‘BROTHGLOW’ was selected as a whole plant mutation in May 2006 and derived from a cross made between ‘YABOS’ (U.S. Plant Pat. No. 20,093) as the female parent and an unnamed F1 hybrid from the Inventors' breeding program as the male parent.

Asexual reproduction of the new cultivar was first accomplished by terminal stem cuttings in Congleton, Cheshire, U.K. in 2006 by one of the Inventors. 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 ‘BROTHGLOW’ as a new and distinct cultivar of Begonia.

• • 1. ‘BROTHGLOW’ exhibits an upright growth habit.
  • 2. ‘BROTHGLOW’ exhibits single male flowers that are apricot in color (female flowers are not produced).
  • 3. ‘BROTHGLOW’ exhibits good basal branching and is particularly unique for its branching from small sized tubers.
  • 4. ‘BROTHGLOW’ exhibits large evenly formed leaves that are dark olive green-bronze in color.

‘BROTHGLOW’ can readily be distinguished from its parents. ‘YABOS’, the female parent, differs from ‘BROTHGLOW’ in having a pendulous plant habit and in having flowers that are red-orange in color. The unnamed male parent differs from ‘BROTHGLOW’ in having flowers that are white in color. ‘BROTHGLOW’ is particularly unique for its combination of its single male only flowers that are apricot in color combined with it multi-branched upright habit and there are no cultivars of Begonia known to the Inventors that are close for comparison. ‘BROTHGLOW’ can be compared to existing cultivars of tuberous type Begonias with flowers that are apricot in color. The cultivars ‘Apricot Delight’ (not patented), Apricot Cascade’ (not patented), and ‘Innbellpea’ (U.S. Plant Pat. No. 20,606) all differ from ‘BROTHGLOW’ in having pendulous plant habits and double flowers. ‘Encanto Orange’ (U.S. Plant Pat. No. 20,898) is similar to ‘BROTHGLOW’ in having single flowers, however the flowers of ‘Encanto Orange’ are bright orange in color and the plant habit is pendulous.

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 August of a plant grown from a single, un-pinched plug in a 2-gallon container in Essex, United Kingdom.

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

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

The photograph in FIG. 3 provides a close-up view of the basal branching.

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 2 months in age as grown in 4.5-inch 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 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
