Abstract

A new and distinct cultivar of Hydrangea plant named ‘SMHMSV’, characterized by its upright, outwardly spreading and mounded plant habit; strong and sturdy stems; light and dark green-colored variegated leaves; mophead and lacecap-type inflorescences with light pink-colored sterile flowers; and good winter hardiness.

Description

Botanical designation: Hydrangea macrophylla.
Cultivar denomination: ‘SMHMSV’.
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 ‘SMHMSV’.
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 is a naturally-occurring branch mutation of Hydrangea macrophylla ‘Shugert’, disclosed in U.S. Plant Pat. No. 21,591. The new Hydrangea plant was discovered and selected by the Inventor on a single plant of ‘Shugert’ from within a population of plants of ‘Shugert’ in 2007.
Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since June, 2007 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 ‘SMHMSV’. These characteristics in combination distinguish ‘SMHMSV’ as a new and distinct Hydrangea plant:
    • 1. Upright, outwardly spreading and mounded plant habit.
    • 2. Strong and sturdy stems.
    • 3. Remontant flowering habit.
    • 4. Light and dark green-colored variegated leaves.
    • 5. Mophead and lacecap-type inflorescences with light pink-colored sterile flowers.
    • 6. Good winter hardiness.
Plants of the new Hydrangea differ from plants of the female parent, ‘Shugert’, in the following characteristics:
    • 1. Plants of the new Hydrangea have variegated leaves whereas plants of ‘Shugert’ have non-variegated leaves.
    • 2. Plants of the new Hydrangea produce mophead and lacecap type inflorescences whereas plants of ‘Shugert’ only produce lacecap type inflorescences.
Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘Variegata’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Variegata’ in the following characteristics:
    • 1. Plants of the new Hydrangea had light and dark green-colored variegated leaves whereas plants of ‘Variegata’ had green and cream-colored variegated leaves.
    • 2. Plants of the new Hydrangea produced mophead and lacecap type inflorescences whereas plants of ‘Variegata’ only produced lacecap type inflorescences.
    • 3. Plants of the new Hydrangea rebloomed whereas plants of ‘Variegata’ did not rebloom.
Plants of the new Hydrangea can also be compared to plants of Hydrangea macrophylla ‘Lemon Wave’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Lemon Wave’ in the following characteristics:
    • 1. Plants of the new Hydrangea had light and dark green-colored variegated leaves whereas plants of ‘Lemon Wave’ had green, yellow and golden yellow-colored variegated leaves.
    • 2. Plants of the new Hydrangea produced mophead and lacecap type inflorescences whereas plants of ‘Lemon Wave’ only produced lacecap type inflorescences.
    • 3. Plants of the new Hydrangea rebloomed whereas plants of ‘Lemon Wave’ did not rebloom.
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 plant of ‘SMHMSV’.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘SMHMSV’.
