Abstract
A new and distinct cultivar of Hydrangea plant named ‘Abetwo’, characterized by its upright and mounded plant habit; strong and sturdy stems; dark green-colored leaves; and large mophead-type inflorescences with numerous white-colored sterile flowers.
Description
Botanical designation: Hydrangea arborescens.
Cultivar denomination: ‘Abetwo’.
The present invention relates to a new and distinct cultivar of Hydrangea, botanically known as Hydrangea arborescens and hereinafter referred to by the name ‘Abetwo’.
The new Hydrangea 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 Hydrangeas with strong stems and attractive foliage and flower coloration.
The new Hydrangea originated from an open-pollination in 2002 of the Hydrangea arborescens ‘Annabelle’, not patented, as the female, or seed parent and an unknown selection of Hydrangea arborescens. The new Hydrangea was discovered and selected by the Inventor in 2004 as a flowering plant within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Grand Haven, Mich.
Asexual reproduction of the new cultivar by softwood cuttings in a controlled environment in Grand Haven, Mich. since 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.
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 ‘Abetwo’. These characteristics in combination distinguish ‘Abetwo’ as a new and distinct cultivar of Hydrangea:
-
- 1. Upright and mounded plant habit.
- 2. Strong and sturdy stems.
- 3. Dark green-colored leaves.
- 4. Large mophead-type inflorescences with numerous white-colored sterile flowers.
Plants of the new Hydrangea differ from plants of the female parent, ‘Annabelle’, in the following characteristics:
-
- 1. Plants of the new Hydrangea are taller than plants of ‘Annabelle’.
- 2. Plants of the new Hydrangea have stronger and thicker stems than plants of ‘Annabelle’.
- 3. Plants of the new Hydrangea have larger inflorescences than plants of ‘Annabelle’.
- 4. Plants of the new Hydrangea have longer peduncles than plants of ‘Annabelle’.
- 5. Plants of the new Hydrangea tolerate rain better than plants of ‘Annabelle’.
Plants of the new Hydrangea can be compared to plants of Hydrangea arborescens ‘White Dome’, not patented. Plants of the new Hydrangea differ from plants of ‘White Dome’ in the following characteristics:
-
- 1. Plants of the new Hydrangea have mophead inflorescences whereas plants of ‘White Dome’ have lacecap inflorescences.
- 2. Plants of the new Hydrangea have showier inflorescences than plants of ‘White Dome’.
The accompanying colored photographs illustrate the unique appearance of the new cultivar, 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.
The photograph at the bottom of the sheet (FIG. 2 ) comprises a side perspective view of a typical flowering plant of ‘Abetwo’ grown in an outdoor nursery.
The photograph at the top of the sheet (FIG. 1 ) is a close-up view of a typical inflorescence of ‘Abetwo’.
Plants used for the aforementioned photographs and the following description were grown in Grand Haven, Mich. in ground beds in an outdoor nursery and under conditions which closely approximate commercial production conditions. Plants of the new Hydrangea had been growing for three years when the photographs and description were taken during the summer. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
