Description

Botanical classification: Begonia boliviensis.

Cultivar designation: ‘YAMOUR’.

RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent applications filed for cultivars derived from the same breeding program entitled Begonia Plant Named ‘YABON’ (U.S. Plant patent application Ser. No. 12/799,033), Begonia Plant Named ‘YAGANCE’ (U.S. Plant Pat. No. 19,817), Begonia Plant Named ‘YAMANCE’ (U.S. Plant Pat. No. 19,777), and 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 Begonia plant, botanically known as Begonia boliviensis ‘YAMOUR’ and will be referred to hereafter by its cultivar name, ‘YAMOUR’.

The new cultivar was derived from a controlled breeding program conducted by the Inventor at his nursery in Congleton, Cheshire, U.K. The overall purpose of the breeding program established in 2003 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. ‘YAMOUR’ was selected in the Inventor's greenhouse in 2006 as a single unique plant from amongst the seedlings derived from a cross made in 2005 between two unnamed, non-commercialized, proprietary parent lines hybrids of Begonia boliviensis.

Asexual reproduction of the new cultivar was first accomplished by terminal stem cuttings in Congleton, Cheshire, U.K. in 2007 by the Inventor. 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 ‘YAMOUR’ as a new and distinct cultivar of Begonia.

    • 1. ‘YAMOUR’ exhibits a semi-pendulous plant habit.
    • 2. ‘YAMOUR’ exhibits large, single red flowers.
    • 3. ‘YAMOUR’ exhibits leaves that are dark purple-green leaves.
    • 4. ‘YAMOUR’ readily produces floriferous side shoots.
    • 5. ‘YAMOUR’ exhibits a vigorous growth habit.

The parent plants of ‘YAMOUR’ differ from ‘YAMOUR’ in that one parent has a large habit with pale red flowers and the other has an upright habit with darker red flowers. ‘YAMOUR’ can be most closely compared to ‘YABOS’. ‘YABOS’ differs from ‘YAMOUR’ in having green leaves, shorter internodes, a less vigorous growth habit and smaller red-orange flowers. ‘YAMOUR’ can also be compared to other cultivars from the same breeding program. ‘YAGANCE’ differs from ‘YAMOUR’ in having bicolor pink and white flowers and ‘YAMANCE’ differs from ‘YAMOUR’ in having flowers that are pink in color. ‘YABON’ differs from ‘YAMOUR’ in having semi-double yellow flowers and a more upright plant habit. ‘YAMOUR’ can be compared to the cultivar ‘Bonfire’ (U.S. Plant Pat. No. 15,108). ‘Bonfire’ differs from ‘YAMOUR’ in having flowers that are smaller and less red in color.
