Abstract
A new and distinct cultivar of Begonia plant named ‘Kerbespicup’, characterized by its broadly upright to semi-trailing plant habit; roughly globular in plant form; moderately vigorous growth habit; freely basal branching habit; dark green-colored leaves; freely flowering habit; fragrant flowers; and large mostly double-type and occasional single-type flowers that are bright yellow in color.
Description

Botanical designation: Begonia x tuberhybrida.


Cultivar denomination: ‘KERBESPICUP’.


BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia x tuberhybrida and hereinafter referred to by the name ‘Kerbespicup’.


The new Begonia plant is a product of a planned breeding program conducted by the Inventors in Cambridge, United Kingdom. The objective of the breeding program is to create new Begonia plants with uniform plant habit and numerous attractive flowers.


The new Begonia plant is a naturally-occurring branch mutation of Begonia x tuberhybrida ‘Kerbespicit’, disclosed in U.S. Plant Pat. No. 29,308. The new Begonia plant was discovered and selected by the Inventors on a single flowering plant from within a population of plants of ‘Kerbespicit’ in a controlled greenhouse environment in Cambridge, United Kingdom in June, 2016.


Asexual reproduction of the new Begonia plant by terminal vegetative cuttings taken in a controlled greenhouse environment in Cambridge, United Kingdom since June, 2016 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.


SUMMARY OF THE 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.


The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kerbespicup’. These characteristics in combination distinguish ‘Kerbespicup’ as a new and distinct Begonia plant:

    • 1. Broadly upright to semi-trailing plant habit; roughly globular in plant form.
    • 2. Moderately vigorous growth habit.
    • 3. Freely basal branching habit.
    • 4. Dark green-colored leaves.
    • 5. Freely flowering habit.
    • 6. Fragrant flowers.
    • 7. Large mostly double-type and occasional single-type flowers that are bright yellow in color.


Plants of the new Begonia differ primarily from plants of the mutation parent, ‘Kerbespicit’, in flower color as plants of the new Begonia have darker yellow-colored flowers than plants of ‘Kerbespicit’.


Plants of the new Begonia can be compared to plants of Begonia x tuberhybrida ‘Fragrant Falls Lemon Fizz’, not patented. In side-by-side comparisons conducted in Cambridge, United Kingdom, plants of the new Begonia differed primarily from plants of ‘Fragrant Falls Lemon Fizz’ in the following characteristics:

    • 1. Plants of the new Begonia are more upright than plants of ‘Fragrant Falls Lemon Fizz’.
    • 2. Plants of the new Begonia have thinner stems than plants of ‘Fragrant Falls Lemon Fizz’.
    • 3. Plants of the new Begonia are more freely branching than plants of ‘Fragrant Falls Lemon Fizz’.
    • 4. Plants of the new Begonia are more freely flowering than plants of ‘Fragrant Falls Lemon Fizz’.
    • 5. Plants of the new Begonia have smaller flowers than plants of ‘Fragrant Falls Lemon Fizz’.


Plants of the new Begonia can also be compared to plants of Begonia x tuberhybrida ‘Scentiment Sunrise’, not patented. In side-by-side comparisons conducted in Cambridge, United Kingdom, plants of the new Begonia differed primarily from plants of ‘Scentiment Sunrise’ in the following characteristics:

    • 1. Plants of the new Begonia are more trailing than and not as upright as plants of ‘Scentiment Sunrise’.
    • 2. Plants of the new Begonia are more freely flowering than plants of ‘Scentiment Sunrise’.
    • 3. Flowers of plants of the new Begonia are not as pendulous as flowers of plants of ‘Scentiment Sunrise’.
    • 4. Plants of the new Begonia have smaller flowers than plants of ‘Scentiment Sunrise’.
    • 5. Plants of the new Begonia have bright yellow-colored flowers whereas plants of ‘Scentiment Sunrise’ have light orange-colored flowers.





BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant.


The photograph on the first sheet (FIG. 1 of 2) comprises a side perspective view of a typical plant of ‘Kerbespicup’ grown in a container.


The photograph on the second sheet (FIG. 2 of 2) is a close up view of typical leaves and male double-type and female single-type flowers of ‘Kerbespicup’.





DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in Loudon, N.H. with three plants in 21.6-cm containers in a glass-covered greenhouse in Loudon, N.H. and under cultural practices typical of commercial Begonia production. During the production of the plants, average daily temperatures ranged from 18° C. to 20° C. Plants were pinched six weeks after planting and were 15 weeks from planting when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except were general terms of ordinary dictionary significance are used. Measurements were taken on individual plants.
