Abstract
A new and distinct cultivar of Hydrangea plant named ‘Robert’, characterized by its upright and mounded plant habit; strong roots and stems; strong and dark green-colored leaves; and large mophead-type inflorescences with dark pink-colored flowers.
Description
Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘Robert’.
The present invention relates to a new and distinct cultivar of Hydrangea, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘Robert’.
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 attractive foliage and flower coloration.
The new Hydrangea originated from an open-pollination in July, 2003 of the Hydrangea macrophylla cultivar Bailmer, disclosed in U.S. Plant Pat. No. 15,298, as the female, or seed parent and an unknown selection of Hydrangea macrophylla. The cultivar Robert 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 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.
The cultivar Robert has 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 ‘Robert’. These characteristics in combination distinguish ‘Robert’ as a new and distinct cultivar of Hydrangea:
-
- 1. Upright and mounded plant habit.
- 2. Strong roots and stems.
- 3. Strong and dark green-colored leaves.
- 4. Large mophead-type inflorescences with dark pink-colored flowers.
Plants of the new Hydrangea differ from plants of the female parent, the cultivar Bailmer, in the following characteristics:
-
- 1. Plants of the new Hydrangea have darker green-colored leaves than plants of the cultivar Bailmer.
- 2. Flowers of plants of the new Hydrangea have larger and thicker sepals than flowers of plants of the cultivar Bailmer.
- 3. Sepals of plants of the new Hydrangea are brighter pink in color than sepals of plants of the cultivar Bailmer.
- 4. With development, sepals of plants of the new Hydrangea turn green in color whereas with development, sepals of plants of the cultivar Bailmer turn brown in color.
Plants of the new Hydrangea can be compared to plants of the cultivar Sonmarie, not patented. Plants of the new Hydrangea differ from plants of the cultivar Sonmarie in the following characteristics:
-
- 1. Plants of the new Hydrangea have glossier and darker green-colored leaves than plants of the cultivar Sonmarie.
- 2. Plants of the new Hydrangea develop inflorescences on new and old wood whereas plants of the cultivar Sonmarie only develop inflorescences on old wood.
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 comprises a side perspective view of a typical flowering plant of ‘Robert’ grown in an outdoor nursery.
The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘Robert’.
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. Plants used in the aforementioned photographs and in 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 were about three years old when the photographs and description were taken during the summer.
