USPP27328P3 - Abelia plant named ‘ABENOV41’ - Google Patents

Abstract

A new cultivar of Abelia plant named, ‘ABENOV41’ that is characterized by its an evergreen plant habit in U.S.D.A. Zone 7, its long and floriferous bloom period, blooming from May to October in France, its large flowers that are pink-violet in color and open from deep pink-purple buds, its bracts that are reddish brown in color, and its moderate to vigorous growth habit.

Description

Botanical classification: Abelia hybrid.

Varietal denomination: ‘ABENOV41’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Abelia of hybrid origin and will be referred to hereafter by its cultivar name, ‘ABENOV41’. ‘ABENOV41’ represents a new Abelia, a shrub grown for landscape use.

The new cultivar is the result of a controlled breeding program conducted by the Inventor in Angers-Beaucouzé, France. The objective of the breeding program is to develop new cultivars of Abelia twith increased cold hardiness and unique flower colors and plant habits.

The new cultivar arose from a cross made by the Inventor in June of 2004 between Abelia schumannii ‘Bumblebee’ (not patented) as the female parent and Abelia×grandiflora ‘Semperflorus’ (not patented) as the male parent. The Inventor selected ‘ABENOV41’ as a single unique plant amongst the seedlings that resulted from the above cross in 2006.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in Angers-Beaucouzé, France in September of 2006. Asexual propagation by softwood stem 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. These attributes in combination distinguish ‘ABENOV41’ as a unique cultivar of Abelia.

• • 1. ‘ABENOV41’ exhibits an evergreen plant habit in U.S.D.A. Zone 7.
  • 2. ‘ABENOV41’ exhibits a long and floriferous bloom period; blooming from May to October in France.
  • 3. ‘ABENOV41’ exhibits large flowers that are pink-violet in color and open from deep pink-purple buds.
  • 4. ‘ABENOV41’ exhibits bracts that are reddish brown in color.
  • 5. ‘ABENOV41’ exhibits a moderate to vigorous growth habit.
    ‘Bumblebee’, the female parent plant of ‘ABENOV41’, differs from ‘ABENOV41’ in having a more compact plant habit, in being less floriferous, and in having smaller flowers that are pale mauve in color. ‘Semperflorus’, the male parent plant of ‘ABENOV41’, differs from ‘ABENOV41’ in having smaller flowers that are white in color, in having foliage that is bright green in color, and in having a shorter blooming period (July to August in France). ‘ABENOV41’ can also be compared to the Abelia cultivars ‘Edward Goucher’ (not patented) and typical plants of the species Abelia engleriana (no patented cultivars known to the Inventor). ‘Edward Goucher’ is similar to ‘ABENOV41’ in overall plant shape and flower color. ‘Edward Goucher’ differs from ‘ABENOV41’ in having flowers that are smaller in size, in having foliage that is brighter green in color, and in being less floriferous. Typical plants of the species Abelia engleriana are similar to ‘ABENOV41’ in having a moderate to vigorous growth habit and in flower color. Typical plants of Abelia engleriana differ from ‘ABENOV41’ in having deciduous plant habits and in having a shorter blooming periods.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Abelia.

The photograph in FIG. 1 was taken of a 3 year-old plant in the garden and provides a side view of the plant habit ‘ABENOV41’ in the early summer.

The photograph in FIG. 2 was taken of a plant 4 years in age as grown in a 17-liter containier provides a side view of a plant of ‘ABENOV41’ in the fall.

The photograph in FIG. 3 was taken of a 3 year-old plant in the garden and provides a close-up of the flowers and flower buds of ‘ABENOV41’ in mid summer.

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 Abelia.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of one year-old plants of the new cultivar as grown outdoors spring through fall and in a greenhouse in 15-cm containers in winter in St. Paul, Minn. 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 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
