plant named ‘Bailras’

Abstract

A new cultivar of Dasiphora plant named ‘Bailras’ that is characterized by its compact and upright, rounded plant habit, its large leaves that are dark green in color, and its single flowers that open deep pink in color with the color resistant to fading under high heat before fading in late summer to white flushed with pink.

Description

Botanical classification: Dasiphora fruiticosa.

Variety denomination: ‘Bailras’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dasiphora fruiticosa. The new cultivar will be referred to hereafter by its cultivar name, ‘Bailras’. ‘Bailras’ is a new cultivar of deciduous shrub grown for landscape use.

The new cultivar is the result of a controlled breeding program conducted by the Inventor in Morden, MB, Canada. The intent of the breeding program is to develop a new cultivar of Dasiphora with flowers that are deep pink in color. ‘Bailras’ originated as a seedling that arose from a cross made in 2009 between unnamed and unpatented plants of Dasiphora fruiticosa from the breeders' program; the female parent designated as accession No. 04221 and the male parent designated as accession No. 98517. ‘Bailras’ was selected as a single unique plant in 2010 from the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings under the direction of the Inventor in Cottage Grove, Minnesota in July of 2010. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and 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 shrub rose. These attributes in combination distinguish ‘Bailras’ as a unique cultivar of Dasiphora.

• • 1. ‘Bailras’ exhibits a compact and upright, rounded plant habit.
  • 2. ‘Bailras’ exhibits large leaves that are dark green in color.
  • 3. ‘Bailras’ exhibits single flowers that open deep pink in color with the color resistant to fading under high heat before fading in late summer to white flushed with pink.

The female parent of ‘Bailras’ differs from ‘Bailras’ in having a low prostrate-type plant habit, pink flowers with white centers that fade to white in mid-summer, and smaller leaves. The male parent of ‘Bailras’ differs from ‘Bailras’ in having white and pink flowers that fade in mid-simmer to white. ‘Bailras’ can be compared to the Dasiphora cultivars ‘Pink Beauty’ (not patented) and ‘SMNPPS’ (U.S. Plant Pat. No. 30,710). ‘Pink Beauty’ is similar to ‘Bailras’ in having an upright rounded plant habit and large leaves. ‘Pink Beauty’ differs from ‘Bailras’ in having flowers that are smaller in size, pink flowers that fade faster to white in mid-summer, and foliage that is lighter green in color. ‘SMNPPS’ is similar to ‘Bailras’ in having dark green foliage and pink flowers. ‘SMNPPS’ differs from ‘Bailras’ in having a smaller plant size and flowers that are pink in color with white centers and smaller in size.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Dasiphora. The photographs were taken of a 2-year-old plant of ‘Bailras’ as grown outdoors in a 2-gallon container in Cottage Grove, Minnesota.

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

The photograph in FIG. 2 provides a provides a close-up view of a flower of ‘Bailras’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Dasiphora.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 2-year-old plants of ‘Bailras’ as grown outdoors in 2-gallon containers in Cottage Grove, Minnesota. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
