plant named ‘Berner’

Abstract

A new and distinct cultivar of Hydrangea plant named ‘Berner’, characterized by its upright and mounded plant habit; strong and sturdy stems; dark green-colored leaves; large mophead-type inflorescences with numerous dark pink-colored sterile flowers; and reblooming habit.

Description

Botanical designation: Hydrangea macrophylla.

Cultivar denomination: ‘BERNER’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘Berner’.

The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new reblooming Hydrangea plants with strong stems and attractive foliage and flower coloration.

The new Hydrangea plant originated from an open-pollination in July, 2003 of the Hydrangea macrophylla ‘Bailmer’, disclosed in U.S. Plant Pat. No. 15,298, as the female, or seed parent and an unknown selection of Hydrangea macrophylla as the male, or pollen, parent. The new Hydrangea plant was discovered and selected by the Inventor in May, 2005 as a flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.

Asexual reproduction of the new cultivar by softwood cuttings in a controlled environment in Grand Haven, Mich. since June, 2005 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. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Berner’. These characteristics in combination distinguish ‘Berner’ as a new and distinct cultivar of Hydrangea plant:

• • 1. Upright and mounded plant habit.
  • 2. Strong and sturdy stems.
  • 3. Dark green-colored leaves.
  • 4. Large mophead-type inflorescences with numerous dark pink-colored sterile flowers.
  • 5. Reblooming habit.

Plants of the new Hydrangea differ from plants of the female parent, ‘Bailmer’, in the following characteristics:

• • 1. Plants of the new Hydrangea have thicker, darker and glossier leaves than plants of ‘Bailmer’.
  • 2. Plants of the new Hydrangea have larger inflorescences than plants of ‘Bailmer’.
  • 3. Plants of the new Hydrangea have more intense and darker pink-colored flowers than plants of ‘Bailmer’.

Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘Robert’, disclosed in U.S. Plant Pat. No. 20,020. In side-by-side comparisons, plants of the new Hydrangea differ from plants of ‘Robert’ in the following characteristics:

• • 1. Plants of the new Hydrangea have stronger stems than plants of ‘Robert’.
  • 2. Plants of the new Hydrangea have larger inflorescences than plants of ‘Robert’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea plant. The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Berner’ grown in an outdoor nursery. The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Berner’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following description were grown during the spring and summer in a 30% shadehouse in Grand Haven, Mich. and under conditions which closely approximate commercial Hydrangea production conditions. Plants of the new Hydrangea were three years old when the photographs and description were taken.
