Abstract
A new and distinct cultivar of Hydrangea plant named ‘SMNHMSIGMA’, characterized by its compact, upright, outwardly spreading and mounding plant habit; strong and sturdy stems; remontant flowering habit; dark green-colored leaves; mophead-type inflorescences with intense deep pink-colored sterile flowers that can easily be “blued” with aluminum sulfate treatments; and good garden performance.
Description
Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘SMNHMSIGMA’.
The present invention relates to a new and distinct Hydrangea plant, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘SMNHMSIGMA’.
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 compact and reblooming Hydrangea plants with strong stems and attractive inflorescences.
The new Hydrangea plant originated from an open-pollination in July, 2008 of Hydrangea macrophylla ‘Robert’, disclosed in U.S. Plant Pat. No. 20,020, 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 as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich. in June, 2011.
Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since June, 2011 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 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 ‘SMNHMSIGMA’. These characteristics in combination distinguish ‘SMNHMSIGMA’ as a new and distinct Hydrangea plant:
-
- 1. Compact, upright, outwardly spreading and mounding plant habit.
- 2. Strong and sturdy stems.
- 3. Remontant flowering habit.
- 4. Dark green-colored leaves.
- 5. Mophead-type inflorescences with intense dark pink-colored sterile flowers that can easily be “blued” with aluminum sulfate treatments.
- 6. Good garden performance.
Plants of the new Hydrangea differ from plants of the female parent, ‘Robert’, in the following characteristics:
-
- 1. Plants of the new Hydrangea have stronger stems than plants of ‘Robert’.
- 2. Sterile flower sepals of plants of the new Hydrangea are richer and more intense in color than sterile flower sepals of plants of ‘Robert’.
- 3. Plants of the new Hydrangea are more easily “blued” with aluminum sulfate than plants of ‘Robert’.
- 4. Plants of the new Hydrangea have a stronger reblooming habit than plants of ‘Robert’.
Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘Nikko Blue’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Nikko Blue’ in the following characteristics:
-
- 1. Sterile flower sepals of plants of the new Hydrangea were darker and more intense in color than sterile flower sepals of plants of ‘Nikko Blue’.
- 2. Plants of the new Hydrangea had a stronger reblooming habit than plants of ‘Nikko Blue’.
Plants of the new Hydrangea can also be compared to plants of Hydrangea macrophylla ‘Berner’, disclosed in U.S. Plant Pat. No. 22,329. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Berner’ in the following characteristics:
-
- 1. Sterile flower sepals of plants of the new Hydrangea were smaller and richer and more intense in color than sterile flower sepals of plants of ‘Berner’.
- 2. Plants of the new Hydrangea had a stronger reblooming habit than plants of ‘Berner’.
- 3. Plants of the new Hydrangea were more easily “blued” with aluminum sulfate than plants of ‘Berner’.
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 ‘SMNHMSIGMA’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of typical inflorescences of ‘SMNHMSIGMA’; the inflorescence on the left is from a plant that was not treated with aluminum sulfate and the inflorescence on the right is from a plant that was treated with aluminum sulfate.
Plants used for the aforementioned photographs and the following description were grown during the summer in three-gallon containers in a polypropylene-covered shadehouse in Grand Haven, Mich. and under cultural practices typical of commercial Hydrangea production. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. Plants of the new Hydrangea were two years old when the photographs and description were taken. Plants were overwintered in a polyethylene-covered greenhouse. Some plants were treated with aluminum sulfate to “blue” the flowers. During the production of the plants, the soil pH ranged from 5.0 to 6.0. 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.
