USPP36598P2 - Buddleia plant named ‘Balchryeel’ - Google Patents

Abstract

A new and distinct cultivar of Buddleia plant named ‘Balchryeel’, characterized by its compact, upright and outwardly spreading plant habit; moderately vigorous growth habit; freely branching habit; dense and bushy appearance; dark green-colored leaves; and relatively long conical inflorescences with numerous bright violet-colored flowers.

Description

Botanical designation: Buddleia davidii X Buddleia hybrida.

Cultivar denomination: ‘BALCHRYEEL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Buddleia plant, commonly referred to as Butterfly Bush, botanically known as Buddleia davidii X Buddleia hybrida and hereinafter referred to by the name ‘Balchryeel’.

The new Buddleia plant is a product of a planned breeding program conducted by the Inventors in Guadalupe, California and West Grove, Pennsylvania. The objective of the breeding program was to create new Buddleia plants with a compact, mounding and freely branching growth habit with numerous flowers and remontant flowering habit.

The new Buddleia plant originated from a cross-pollination in Guadalupe, California of Buddleia davidii ‘Lavender Cascade’, disclosed in U.S. Plant Pat. No. 30,635, as the female, or seed, parent with a proprietary selection of Buddleia hybrida identified as code number 4548-A, not patented, as the male, or pollen, parent. The new Buddleia plant was discovered and selected by the Inventors as a single plant within the progeny of the stated open-pollination in a controlled environment in West Grove, Pennsylvania in August 2020.

Asexual reproduction of the new Buddleia plant by terminal stem cuttings in a controlled environments in Guadalupe, California and West Grove, Pennsylvania since August 2020 has shown that the unique features of this new Buddleia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Buddleia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balchryeel’. These characteristics in combination distinguish ‘Balchryeel’ as a new and distinct Buddleia plant:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit; dense and bushy appearance.
  • 4. Dark green-colored leaves.
  • 5. Relatively long conical inflorescences with numerous bright violet-colored flowers.

Plants of the new Buddleia differ primarily from plants of the female parent, ‘Lavender Cascade’ in flower color as plants of the new Buddleia have bright violet-colored flowers whereas plants of ‘Lavender Cascade’ have light purple-colored flowers. In addition, the lower surfaces of leaves of plants of the new Buddleia are medium green in color whereas the lower surfaces of leaves of plants of ‘Lavender Cascade’ are silvery in color.

Plants of the new Buddleia differ primarily from plants of the male parent selection in flower color as plants of the new Buddleia have bright violet-colored flowers whereas plants of the male parent selection have dark purple-colored flowers. In addition, the lower surfaces of leaves of plants of the new Buddleia are medium green in color whereas the lower surfaces of leaves of plants of ‘Lavender Cascade’ are silvery in color.

Plants of the new Buddleia can be compared to plants of Buddleia davidii ‘Tobudpipur’, disclosed in U.S. Plant Pat. No. 22,064. In side-by-side comparisons, plants of the new Buddleia differ primarily from plants of ‘Tobudpipur’ in flower color as plants of the new Buddleia have bright violet-colored flowers whereas plants of ‘Tobudpipur’ have dark purple-colored flowers. In addition, plants of the new Buddleia are more outwardly spreading than and not as upright as plants of ‘Tobudpipur’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Buddleia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Buddleia plant.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘Balchryeel’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical inflorescence of ‘Balchryeel’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 10-cm containers in a polyethylene-covered greenhouse in West Chicago, Illinois during the late winter and early spring and under cultural practices similar to those used in commercial Buddleias plant production. During the production of the plants, day temperatures averaged 25° C. and night temperatures averaged 10° C. Plants were pinched twice and were twelve weeks from planting rooted young plants when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Sixth Edition, except where general terms of ordinary dictionary significance are used. Measurements represent averages for typical flowering plants.
