Abstract

A new and distinct cultivar of Hydrangea plant named ‘SMNHPPINKA’, characterized by its upright and somewhat outwardly spreading plant habit; strong and sturdy stems; freely flowering habit; showy inflorescences with sterile flowers that are initially white in color and becoming hot pink to red in color; and good garden performance.

Description

Botanical designation: Hydrangea paniculata.
Cultivar denomination: ‘SMNHPPINKA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Hydrangea plant, botanically known as Hydrangea paniculata and hereinafter referred to by the name ‘SMNHPPINKA’.
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 early-flowering Hydrangea plants with strong stems and large and attractive inflorescences.
The new Hydrangea plant originated from an open-pollination in July, 2004 of Hydrangea paniculata ‘Little Lamb’, disclosed in U.S. Plant Pat. No. 15,395, as the female, or seed parent and an unknown selection of Hydrangea paniculata 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 July, 2009.
Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since June, 2010 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 ‘SMNHPPINKA’. These characteristics in combination distinguish ‘SMNHPPINKA’ as a new and distinct Hydrangea plant:
    • 1. Upright and somewhat outwardly spreading plant habit.
    • 2. Strong and sturdy stems.
    • 3. Freely flowering habit.
    • 4. Showy inflorescences with sterile flowers that are initially white in color and becoming hot pink to red in color.
    • 5. Good garden performance.
Plants of the new Hydrangea differ from plants of the female parent, ‘Little Lamb’, in the following characteristics:
    • 1. Plants of the new Hydrangea are larger than plants of ‘Little Lamb’.
    • 2. Plants of the new Hydrangea have stronger stems than plants of ‘Little Lamb’.
    • 3. Plants of the new Hydrangea and ‘Little Lamb’ differ in sterile flower color as plants of ‘Little Lamb’ have pink-colored sterile flowers.
Plants of the new Hydrangea can be compared to plants of Hydrangea paniculata ‘Limelight’, disclosed in U.S. Plant Pat. No. 12,874. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Limelight’ in the following characteristics:
    • 1. Plants of the new Hydrangea were more compact than plants of ‘Limelight’.
    • 2. Plants of the new Hydrangea and ‘Limelight’ differed in sterile flower color as plants of ‘Limelight’ had light green-colored sterile flowers.
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 ‘SMNHPPINKA’ growing in an outdoor nursery.
The photograph on the second sheet is a close-up view of a typical fully developed inflorescence of ‘SMNHPPINKA’.
Plants used in the photographs were three years old.
 DETAILED BOTANICAL DESCRIPTION
Plants used for 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.

Plants of the new Hydrangea were two years old when the photographs and description were taken. Plants were overwintered in a polyethylene-covered greenhouse.
