plant named ‘YANTANA’

Abstract

A new cultivar of hybrid Begonia named ‘YANTANA’, characterized by its large flowers with light yellow-orange centers and dark pinkish red margins in color with a high degree of upward and horizontal facing flowers, its semi-double sterile male flowers and single female flowers with modified stigmas that have been observed to lack both self-pollination and cross-pollination, its flowers that are long-lived due to lack of pollination making it useful for use in flowerbeds, containers, and baskets, and its compact, mounded and well-branched habit without cane production in its first year of growth.

Description

Botanical classification: Begonia hybrid.

Cultivar designation: ‘YANTANA’ .

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 ‘YANTANA’ and will be referred to hereafter by its cultivar name, ‘YANTANA’. ‘YANTANA’ 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 selections of Begonia plants to produce good basket and patio plants. ‘YANTANA’ was selected in the Inventor's greenhouse in July of 2008 as a single unique plant from amongst the seedlings derived from a cross made in 2007 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 fall of 2011 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 ‘YANTANA’ as a new and distinct cultivar of Begonia.

• • 1. ‘YANTANA’ exhibits large flowers with light yellow-orange centers and dark pinkish red margins in color.
  • 2. ‘YANTANA’ exhibits semi-double sterile male flowers and single female flowers with modified stigmas that have been observed to lack both self-pollination and cross-pollination.
  • 3. ‘YANTANA’ exhibits flowers that are long-lived due to lack of pollination making it useful for use in flowerbeds, containers, and baskets.
  • 4. ‘YANTANA’ exhibits flowers that have a high degree of upward and horizontal facing flowers.
  • 5. ‘YANTANA’ exhibits a compact, mounded and well-branched habit without cane production in its first year of growth.
    The female parent of ‘YANTANA’ differs from ‘YANTANA’ in having pink to pale rose colored flowers with many veins and tepal edges that are ragged. The male parent is similar to ‘YANTANA’ in plant habit but differs from ‘YANTANA’ in having pinkish red flowers. ‘YANTANA’ can be most closely compared to cultivars from the same breeding program: ‘YASPWHIT’, ‘YASPMON’, ‘YASPRINK’, and ‘YASPED’. ‘YASPWHIT’ differs from ‘YANTANA’ in having white flowers lightly flushed with pink with broader tepals. ‘YASPMON’ differs from ‘YANTANA’ in having flowers that are pink-orange in color and a more trailing plant habit. ‘YASPRINK’ differs from ‘YANTANA’ in having pink flowers. ‘YASPED’ differs from ‘YANTANA’ in having dark red flowers, a more pendulous plant habit and in having a more vigorous growth habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Begonia. The photograph was taken of a plant approximately three months in age as grown in a 25-cm container in an unheated greenhouse under ambient light in Congleton, Cheshire, United Kingdom.

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

The photograph in FIG. 2 provides a close-up view of the female flowers.

The photograph in FIG. 3 provides a close-up view of the male flowers.

The photograph in FIG. 4 provides a close-up view of both the female and male flowers.

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.
