Abstract

A new and distinct cultivar of Hydrangea plant named ‘SMHMES14’, characterized by its upright, outwardly spreading and mounded plant habit; strong and sturdy dark brown-colored stems; early flowering habit; large mophead-type inflorescences with large sterile flowers; sterile flowers dark pink or blue in color depending on aluminum sulfate treatments; and good winter hardiness.

Description

Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘SMHMES14’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Hydrangea plant, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘SMHMES14’.
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 Hydrangea plants with reblooming habit, strong stems and attractive inflorescences.
The new Hydrangea plant originated from an open-pollination during the summer of 2003 of Hydrangea macrophylla ‘Bailmer’, disclosed in U.S. Plant Pat. No. 15,298, as the female, or seed parent with 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 May, 2005.
Asexual reproduction of the new Hydrangea plant 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 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 ‘SMHMES14’. These characteristics in combination distinguish ‘SMHMES14’ as a new and distinct Hydrangea plant:
    • 1. Upright, outwardly spreading and mounded plant habit.
    • 2. Strong and sturdy dark brown-colored stems.
    • 3. Early flowering habit.
    • 4. Large mophead-type inflorescences with large sterile flowers.
    • 5. Sterile flowers dark pink or blue in color depending on aluminum sulfate treatments.
    • 6. Good winter hardiness.
Plants of the new Hydrangea differ from plants of the female parent, ‘Bailmer’, in the following characteristics:
    • 1. Plants of the new Hydrangea have stronger, sturdier and darker-colored stems than plants of ‘Bailmer’.
    • 2. Sepals of sterile flowers of plants of the new Hydrangea have acute apices whereas sepals of sterile flowers of ‘Bailmer’ have obtuse apices.
    • 3. Sepal color of sterile flowers of the new Hydrangea is more intense and richer than sepal color of sterile flowers of ‘Bailmer’.
    • 4. Plants of the new Hydrangea are more winter hardy than plants of ‘Bailmer’.
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. Plants of the new Hydrangea flowered about three to four weeks earlier than plants of ‘Nikko Blue’.
    • 2. Sepals of sterile flowers of plants of the new Hydrangea had acute apices whereas sepals of sterile flowers of ‘Nikko Blue’ had obtuse apices.
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 top perspective view of a typical flowering plant of ‘SMHMES14’ grown without aluminum sulfate treatments.
The photograph on the second sheet is a close-up view of typical inflorescences of ‘SMHMES14’ grown without aluminum sulfate treatments.
The photograph on the third sheet comprises a top perspective view of a typical flowering plant of ‘SMHMES14’ grown with aluminum sulfate treatments.
The photograph on the fourth sheet is a close-up view of typical inflorescences of ‘SMHMES14’ grown with aluminum sulfate treatments.
 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 shadehouse 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.
