Begonia plant named ‘BEYZ0002’

Abstract

A new Begonia plant named ‘BEYZ0002’ characterized by its compact, symmetrical and rounded habit, double white flowers that bloom continuously from spring until fall, prolific and continuous basal branching and foliage that is very dark, glosssy and mahogany in color with bright green contrasting veins.

Description

Latin name of the genus and species of the plant claimed: Begonia hybrida.

Varietal denomination: ‘BEYZ0002’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Begonia plant, botanically known as Begonia hybrida, and hereinafter referred to by the variety name ‘BEYZ0002’. ‘BEYZ0002’ is a product of a planned breeding program in Whitecourt, Alberta, Canada. The new cultivar ‘BEYZ0002’ has compact, symmetrical and rounded habit, double white flowers that bloom continuously from spring until fall, continuous basal branching and foliage that is dark, glossy and mahogany in color with bright green contrasting veins.

The new Begonia cultivar, ‘BEYZ0002’, is the result of a planned pollination conducted at the inventor's nursery made in August 2018. The female parent of the new cultivar is the unnamed white seedling, of proprietary origin, unpatented, characterized by its larger flowers and leaves. ‘BEYZ0002’ differs from unnamed white seedling of the inventor's proprietary selection, unpatented by having a smaller flower and leaf size.

The male parent of the new cultivar is the unnamed seedling of proprietary selection, unpatented, having a smaller overall plant habit than ‘BEYZ0002’. The resulting seed was sown in Whitecourt, Alberta, Canada in a controlled greenhouse environment in 2018 and ‘BEYZ0002’ was selected as one flowering plant within the progeny of the stated cross in May 2019.

The first act of asexual reproduction of ‘BEYZ0002’ was accomplished when vegetative tip cuttings were propagated from the initial selection in May 2019 at the inventor's nursery in May 2018 in Whitecourt, Alberta, Canada.

BRIEF SUMMARY OF INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

A Plant Breeder's Right for this cultivar has not yet been applied for. ‘BEYZ0002’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained directly from the inventor.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Begonia as a new and distinct variety.

• 1. ‘BEYZ0002’ has a compact, symmetrical and freely branching habit.
• 2. ‘BEYZ0002’ flowers naturally and continually from spring to fall.
• 3. ‘BEYZ0002’ exhibits continuous basal branching.
• 4. ‘BEYZ0002’ achieves a height of 25 cm high and 30 cm wide in one season grown in a one gallon pot in the greenhouse.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘BEYZ0002’ with colors being as true as possible with an illustration of this type.

The photographic drawings show in FIG. 1 a close view of an inflorescence taken in Whitecourt, Alberta, Canada in August 2023, and in

FIG. 2 a whole flowering plant taken in Whitecourt, Alberta, Canada in August 2023. The plant in the photographic drawings is 16 weeks old and is in an 8″ pot. The plant was grown at the inventor's greenhouse, under natural light in Whitecourt, Alberta, Canada during the summer of 2023.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Whitecourt, Alberta, Canada in August 2023. The plants were approximately 6 months old and were growing in 8 inch pots, one plant per pot, in a greenhouse.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
