plant named ‘Brother Edward’

Abstract

A new and distinct cultivar of Hydrangea plant named ‘Brother Edward’, characterized by its compact, upright and outwardly spreading plant habit; vigorous growth habit; strong and sturdy stems; long flowering period; and large inflorescences with white-colored flowers.

Description

Botanical designation: Hydrangea quercifolia.

Cultivar denomination: ‘BROTHER EDWARD’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Hydrangea plant, botanically known as Hydrangea quercifolia and hereinafter referred to by the name ‘Brother Edward’.

The new Hydrangea plant is a product of a planned breeding program conducted by the Inventors in Cleveland, Ala. The objective of the breeding program was to develop new Hydrangea plants with interesting inflorescence forms.

The new Hydrangea plant originated from an open-pollination in 1988 of an unnamed seedling selection of Hydrangea quercifolia, not patented, as the female, or seed parent with an unknown selection of Hydrangea quercifolia as the male, or pollen, parent. The new Hydrangea plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Cleveland, Ala. in 1993.

Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Cleveland, Ala. since July, 2004 has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Hydrangea have not been observed under all possible 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 ‘Brother Edward’. These characteristics in combination distinguish ‘Brother Edward’ as a new and distinct Hydrangea plant:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Vigorous growth habit.
  • 3. Strong and sturdy stems.
  • 4. Long flowering period.
  • 5. Large inflorescences with white-colored flowers.

Plants of the new Hydrangea differ from plants of the female parent selection in the following characteristics:

• • 1. Inflorescences of plants of the new Hydrangea are denser than inflorescences of plants of the female parent selection.
  • 2. Flowers of plants of the new Hydrangea become green with age whereas flowers of plants of the female parent selection become pink with age.
  • 3. Plants of the new Hydrangea do not produce seed whereas plants of the female parent selection produce seed.

Plants of the new Hydrangea can be compared to plants of Hydrangea quercifolia ‘Harmony’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Harmony’ in the following characteristics:

• • 1. Plants of the new Hydrangea were more compact than plants of ‘Harmony’.
  • 2. Inflorescences of plants of the new Hydrangea were more rain-tolerant than inflorescences of plants of ‘Harmony’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

The photograph comprises a top perspective view of a typical flowering plant of ‘Brother Edward’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following description were grown during the summer in three-gallon containers in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial Hydrangea production. Plants of the new Hydrangea were three years old when the photographs and description were taken.
