Abstract

A new cultivar of hybrid Begonia, ‘TESSDARK’, that is characterized by its compact, spreading, semi-pendulous plant habit, its floriferous plant habit, its flowers that are red-orange in color, its flowers with tepals that are wide and short, and its foliage that is dark green in color on the upper surface and red on the lower surface.

Description

Botanical classification: Begonia hybrid.
Cultivar designation: ‘TESSDARK’.
RELATED APPLICATIONS
This application is related to U.S. Plant Patent applications filed for cultivars derived from the same breeding program entitled Begonia Plant named ‘YASPWHIT’ (U.S. Plant Pat. No. 23,281), Begonia Plant Named ‘YASPMON’ (U.S. Plant Pat. No. 20,846), Begonia Plant Named ‘YASPRINK’ (U.S. Plant Pat. No. 23,266), and Begonia Plant Named ‘YASPED’ (U.S. Plant Pat. No. 22,412).
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Begonia plant, botanically an interspecific hybrid that includes Begonia boliviensis hybrids in its parentage. The new cultivar is known as Begonia ‘TESSDARK’ and will be referred to hereafter by its cultivar name, ‘TESSDARK’. ‘TESSDARK’ is a new cultivar of Begonia that is particular useful for use in flowerbeds, containers, and hanging baskets.
The new cultivar was derived from a controlled breeding program conducted by the inventor at his nursery in Congleton, Cheshire, United Kingdom. The overall purpose of the breeding program is to make unique selections of Begonia plants that perform well as basket and patio plants. ‘TESSDARK’ was selected in the Inventor's greenhouse in 2007 as a single unique plant from amongst the seedlings derived from a cross made in 2006 between unnamed Begonia plants of hybrid origin from the Inventor's breeding program as the female and male parents.
Asexual propagation of the new cultivar was first accomplished by stem tip cuttings in Congleton, Cheshire, United Kingdom in 2007 by the Inventor. Asexual propagation by stem tip cuttings has determined that the characteristics of the new 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 ‘TESSDARK’ as a new and distinct cultivar of Begonia.
    • 1. ‘TESSDARK’ exhibits a compact, spreading, semi-pendulous plant habit.
    • 2. ‘TESSDARK’ exhibits a floriferous blooming habit.
    • 3. ‘TESSDARK’ exhibits flowers that are red-orange in color.
    • 4. ‘TESSDARK’ exhibits flowers with tepals that are wide and short.
    • 5. ‘TESSDARK’ exhibits foliage that is dark green in color on the upper surface and red on the lower surface.
The female parent of ‘TESSDARK’ differs from ‘TESSDARK’ in having flowers with tepals that are not as wide, in having a less vigorous growth rate, in having a more open plant habit, and in being less floriferous. The male parent differs from ‘TESSDARK’ in having leaves that are lighter green in color, in having flowers that are pale orange in color, in having a more mounded plant habit, and in being less floriferous. ‘TESSDARK’ can be most closely compared to cultivars from the same breeding program: ‘YASPWHIT’, ‘YASPMON’, ‘YASPRINK’, and ‘YASPED’. ‘YASPWHIT’ differs from ‘TESSDARK’ in having white flowers lightly flushed with pink. ‘YASPMON’ differs from ‘TESSDARK’ in having flowers that are pink-orange in color and a more trailing plant habit. ‘YASPRINK’ differs from ‘TESSDARK’ in having pink flowers. ‘YASPED’ differs from ‘TESSDARK’ in having dark red flowers, a more pendulous plant habit and in having a more vigorous growth habit.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Begonia. The photographs were taken of 3 cuttings in a 15-cm container, approximately three months in age, as grown in an unheated greenhouse in Naadvijk, The Netherlands.
The photograph in FIG. 1 provides a view of the plant habit of ‘TESSDARK’ in bloom.
The photograph in FIG. 2 provides a close-up view of the upper surface of a leaf of ‘TESSDARK’.
The photograph in FIG. 3 provides a close-up view of the lower surface of a leaf of ‘TESSDARK’.
The photograph in FIG. 4 provides a close-up view of a male flower of ‘TESSDARK’.
The photograph in FIG. 5 provides a close-up view of a female flower of ‘TESSDARK’.
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
