Abstract

A new and distinct cultivar of Hydrangea plant named ‘SMHPLQF’, characterized by its relatively compact, upright and somewhat outwardly spreading plant habit; strong and sturdy stems; early flowering habit; and inflorescences with light pink-colored sterile flowers that become red purple with development in the autumn.

Description

Botanical designation: Hydrangea paniculata.
Cultivar denomination: ‘SMHPLQF’.
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 ‘SMHPLQF’.
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 strong stems and large and attractive inflorescences.
The new Hydrangea plant originated from an open-pollination during the spring of 2004 of Hydrangea paniculata ‘Bulk’, disclosed in U.S. Plant Pat. No. 16,812, 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. during the spring of 2009.
Asexual reproduction of the new Hydrangea plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since the spring of 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 ‘SMHPLQF’. These characteristics in combination distinguish ‘SMHPLQF’ as a new and distinct Hydrangea plant:
    • 1. Relatively compact, upright and somewhat outwardly spreading plant habit.
    • 2. Strong and sturdy stems.
    • 3. Early flowering habit.
    • 4. Inflorescences with light pink-colored sterile flowers that become red purple with development in the autumn.
Plants of the new Hydrangea differ from plants of the female parent, ‘Bulk’, in the following characteristics:
    • 1. Plants of the new Hydrangea are more compact than plants of ‘Bulk’.
    • 2. Plants of the new Hydrangea flower earlier than plants of ‘Bulk’.
    • 3. In the autumn, plants of the new Hydrangea have sterile flowers that are red purple in color whereas plants of ‘Bulk’ have sterile flowers that are dark pink in color.
Plants of the new Hydrangea can be compared to plants of Hydrangea paniculata ‘Pinky Winky’, not patented. In side-by-side comparisons, plants of the new Hydrangea differed primarily from plants of ‘Pinky Winky’ in the following characteristics:
    • 1. Plants of the new Hydrangea were more compact than plants of ‘Pinky Winky’.
    • 2. Plants of the new Hydrangea flowered earlier than plants of ‘Pinky Winky’.
    • 3. Plants of the new Hydrangea had smaller inflorescences than plants of ‘Pinky Winky’.
    • 4. In the autumn, plants of the new Hydrangea had sterile flowers that were red purple in color whereas plants of ‘Pinky Winky’ had sterile flowers that were dark pink in color.
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 ‘SMHPLQF’ in the summer.
The photograph on the second sheet comprises a side perspective view of a typical flowering plant of ‘SMHPLQF’ in the autumn.
The photograph on the third sheet is a close-up view of a typical flowering plant of ‘SMHPLQF’ in the autumn.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and the following description were grown during the spring and 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. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
