Abstract

A new and distinct cultivar of Hydrangea plant named ‘SMNHSG’, characterized by its upright and outwardly spreading plant habit; moderately vigorous growth habit; strong and sturdy stems; dark green-colored leaves; freely and remontant flowering habit with numerous panicles per plant; showy lacecap inflorescences with purplish red-colored sterile flowers that when “blued” are purple in color; and good garden performance.

Description

Botanical designation: Hydrangea serrata.
Cultivar denomination: ‘SMNHSG’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Hydrangea plant, botanically known as Hydrangea serrata, commonly referred to as Mountain Hydrangea and hereinafter referred to by the name ‘SMNHSG’.
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 freely and remontant flowering Hydrangea plants with strong stems and attractive lacecap inflorescences.
The new Hydrangea plant originated from a cross-pollination during the summer of 2016 of Hydrangea serrata ‘MAK20’, disclosed in U.S. Plant Pat. No. 24,820, as the female, or seed parent and Hydrangea serrata ‘Dariya’, 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. during the summer of 2018.
Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since the summer of 2018 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 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 ‘SMNHSG’. These characteristics in combination distinguish ‘SMNHSG’ as a new and distinct Hydrangea plant:
    • 1. Upright and outwardly spreading plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Strong and sturdy stems.
    • 4. Dark green-colored leaves.
    • 5. Freely and remontant flowering habit with numerous panicles per plant.
    • 6. Showy lacecap inflorescences with purplish red-colored sterile flowers that when “blued” are purple in color.
    • 7. Good garden performance.
Plants of the new Hydrangea differ from plants of the female parent, ‘MAK20’, in the following characteristics:
    • 1. Sterile flowers of plants of the new Hydrangea have smaller sepals than sterile flowers of plants of ‘MAK20’.
    • 2. Sepals of sterile flowers of plants of the new Hydrangea are more intense purplish red in color than sepals of sterile flowers of plants of ‘MAK20’.
Plants of the new Hydrangea differ from plants of the male parent, ‘Dariya’, primarily in plant habit as plants of the new Hydrangea are more uniformly mounded than plants of ‘Dariya’.
Plants of the new Hydrangea can be compared to plants of Hydrangea hybrida ‘SMNMAKTSR’, disclosed in U.S. Plant Pat. No. 28,672. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘SMNMAKTSR’ in the following characteristics:
    • 1. Sterile flowers of plants of the new Hydrangea have larger sepals than sterile flowers of plants of ‘SMNMAKTSR’.
    • 2. Sepals of sterile flowers of plants of the new Hydrangea are purplish red in color whereas sepals of sterile flowers of plants of ‘SMNMAKTSR’ are darker and more reddish pink in color.
    • 3. Plants of the new Hydrangea have a more freely and remontant flowering habit than plants of ‘SMNMAKTSR’.
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 (FIG. 1 ) comprises a side perspective view of a typical flowering plant of ‘SMNHSG’ growing in an outdoor nursery.
The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical fully developed inflorescence of ‘SMNHSG’ that has not been “blued”.
The photograph on the third sheet (FIG. 3 ) is a close-up view of a typical fully developed inflorescence of ‘SMNHSG’ that has been “blued”.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the following description were grown during the summer in three-gallon containers in a polyethylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial Hydrangea production.
