Abstract

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

Description

Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘SMHMLDD’.
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 ‘SMHMLDD’.
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 flower coloration.
The new Hydrangea plant originated from a cross-pollination during the summer of 2007 of Hydrangea macrophylla ‘Lynn’, disclosed in U.S. Plant Pat. No. 20,019, as the female, or seed parent and Hydrangea macrophylla ‘ES5’, not patented, 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 cross-pollination in a controlled environment in Grand Haven, Mich. in 2009.
Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since July, 2009 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 ‘SMHMLDD’. These characteristics in combination distinguish ‘SMHMLDD’ as a new and distinct Hydrangea plant:
    • 1. Upright and mounded plant habit.
    • 2. Strong and sturdy stems.
    • 3. Dark green-colored leaves.
    • 4. Large lacecap-type inflorescences with large soft pink-colored sterile flowers and red purple-colored fertile flowers.
    • 5. Reblooming habit.
Plants of the new Hydrangea differ from plants of the female parent, ‘Lynn’, in the following characteristics:
    • 1. Plants of the new Hydrangea have larger inflorescences than plants of ‘Lynn’.
    • 2. Plants of the new Hydrangea have larger sterile flowers than plants of ‘Lynn’.
    • 3. Plants of the new Hydrangea have lighter pink-colored sterile flowers than plants of ‘Lynn’.
Plants of the new Hydrangea differ from plants of the male parent, ‘ES5’, in the following characteristics:
    • 1. Plants of the new Hydrangea have larger inflorescences than plants of ‘ES5’.
    • 2. Plants of the new Hydrangea have larger sterile flowers than plants of ‘ES5’.
Plants of the new Hydrangea can be compared to plants of Hydrangea serrata ‘Mak20’, disclosed in U.S. Plant patent application Ser. No. 13/573,841. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Mak20’ in the following characteristics:
    • 1. Plants of the new Hydrangea had larger inflorescences than plants of ‘Mak20’.
    • 2. Plants of the new Hydrangea had larger sterile flowers than plants of ‘Mak20’.
    • 3. Plants of the new Hydrangea had lighter pink-colored sterile flowers than plants of ‘Mak20’.
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 ‘SMHMLDD’.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘SMHMLDD’.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and the following description were grown during the summer in two-gallon containers in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial Hydrangea production. Plants of the new Hydrangea were two years old when the photographs and description were taken.
