Abstract

A new and distinct cultivar of Hydrangea plant, referred to by its cultivar name, ‘3792resgea’, is disclosed. The new variety forms dark pink-colored inflorescences. Very strong stems which prevent flopping are formed. A moderately vigorous, well-branched, dense, and compact growth habit is displayed. The new variety is well suited for providing ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Hydrangea arborescens.

Variety denomination: ‘3792resgea’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was July 2024, in the United States of America, at the New Varieties Showcase at the Cultivate Trade Show in Columbus, Ohio, followed by the publication of the 2025 Star Roses and Plants Woody Ornamentals & Edibles Catalog released Oct. 7, 2024. The first offer for sale of the new variety was by an inventor or another who obtained the new variety directly or indirectly from an inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new cultivar originated in Cochranville, Pennsylvania in June 2016 in a controlled breeding program. The breeding program's objective was the development of Hydrangea cultivars that have improved compact growth habits with sturdy non-flopping flowers in a range of colors with good leaf spot resistance. The new cultivar is the result of open pollination. The female parent (i.e., the seed parent) of the new cultivar is an unnamed seedling that is the product of the cross of Hydrangea arborescens ‘NCHA2’ (U.S. Plant Pat. No. 28,316) and Hydrangea arborescens ‘PIIHA-I’ (U.S. Plant Pat. No. 21,227). The male parent (i.e., the pollen parent) is unknown.

The parentage of the new variety can be summarized as follows:
(‘NCHA2’ x ‘PIIHA-I’) x unknown

The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated experiment during June 2021 in a controlled environment in Cochranville, Pennsylvania.

The new variety has been found to undergo asexual propagation in Cochranville, Pennsylvania by terminal stem cuttings. Asexual propagation by terminal stem cuttings in Cochranville, Pennsylvania has shown that the characteristics of the new variety are stable and are strictly transmissible by asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of Hydrangea plant of the present invention possesses the following combination of characteristics:

- (a) forms dark pink-colored inflorescences, and
- (b) displays a well-branched, dense, and compact growth habit.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, plants of the new cultivar differ from the female parent variety (i.e., product of ‘NCHA2’ x ‘PIIHA-I’) in that the new cultivar has stronger stems preventing flopping, whereas the female parent variety does flop.

Moreover, the new variety can be readily distinguished from other similar non-parental varieties. Of the many commercially available Hydrangea cultivars, the most similar in comparison to the new cultivar is the ‘NCHA2’ variety (U.S. Plant Pat. No. 28,316). However, in comparison, plants of the new cultivar differ from plants of the ‘NCHA2’ variety at least because the new cultivar has inflorescences that are darker pink than the inflorescences of the ‘NCHA2’ variety, and has sturdier stems that are more resistant to flopping than plants of the ‘NCHA2’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of a plant of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘3792resgea’ variety. The plant of the new cultivar was approximately two years old and was observed in July 2024, while growing in a two-gallon container in Cochranville, Pennsylvania, U.S.A.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2015 edition), London, England, except where general color terms of ordinary significance are used. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms and The R.H.S. Colour Chart designation used herein represents the closest color observed on the majority of the specified botanical feature. The color values were determined in June 2024, under natural light conditions in Cochranville, Pennsylvania. The description is based on the observation of plants produced from cuttings from stock plants and grown in three-gallon containers for approximately two years in an outdoor nursery in Cochranville, Pennsylvania. Measurements and numerical values represent averages of typical plants.
