plant named ‘WNHYDFBPBMH’

- WinGen LLC

A new and distinct cultivar of Hydrangea plant named ‘WNHYDFBPBMH’ is disclosed, characterized by mophead inflorescences, emerging from both terminal and lateral buds. Sepals emerge greenish-white, then stay pink or light blue for the duration of inflorescence (depending upon soil pH and treatment). Plants flower early, and have mounded, cascading habits. The new variety is a Hydrangea, typically produced as an outdoor ornamental plant.

Description

Latin name of the genus and species: Hydrangea hybrid.

Variety denomination: ‘WNHYDFBPBMH’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program conducted by the inventor, at a commercial nursery in Higashiomi, Shiga, Japan. The objective of the breeding program was to produce new mophead Hydrangea varieties with cascading habits. The crossing resulting in the new variety was made in May of 2017.

The seed parent is the variety Hydrangea macrophylla, ‘Cotton Candy’, unpatented. The pollen parent is an unnamed, unpatented specimen of the variety Hydrangea luteovenosa. The new variety was found and selected by the inventor in June of 2019 at the same nursery in Higashiomi, Shiga, Japan.

Asexual reproduction of the new cultivar ‘WNHYDFBPBMH’ was first performed during October of 2019 in Higashiomi, Shiga, Japan, by terminal cuttings. Through subsequent propagation, multiple additional generations have been reproduced, having shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘WNHYDFBPBMH’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘WNHYDFBPBMH.’ These characteristics in combination distinguish ‘WNHYDFBPBMH’ as a new and distinct Hydrangea cultivar:

    • 1. Mophead inflorescences which emerge from both terminal and lateral buds.
    • 2. Sepals emerge greenish-white then stay pink or light blue for the duration of the inflorescence (depending upon soil pH and treatment).
    • 3. Cascading/trailing type habit.
    • 4. Leaf shape and size is intermediate between Hydrangea macrophylla and Hydrangea luteovenosa.

PARENT COMPARISONS

Plants of ‘WNHYDFBPBMH’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of ‘WNHYDFBPBMH’ differ in the following:

    • 1. Leaves of the new variety are medium sized, while leaves of the seed parent are large.
    • 2. Flowers of the new variety set on terminal and lateral buds, while flowers of the seed parent set only on terminal buds.
    • 3. The new variety flowers earlier than the seed parent.
    • 4. Growth habit of the new variety is weeping/cascading, while the growth habit of the seed parent is upright.

Plants of ‘WNHYDFBPBMH’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of ‘WNHYDFBPBMH’ differ in the following:

    • 1. Leaves of the new variety are medium sized, while leaves of the pollen parent are small.
    • 2. Flower sepals of the new variety are larger than flower sepals of the pollen parent.
    • 3. Inflorescences of the new variety are mophead, while inflorescences of the pollen parent are lacecap.

COMMERCIAL COMPARISON

Plants of the new cultivar Hydrangea ‘WNHYDFBPBMH’ can be compared to the commercial variety Hydrangea ‘USHYD0405’, U.S. Plant Pat. No. 31,120. Plants of ‘WNHYDFBPBMH’ are similar to plants of ‘USHYD0405’ in most horticultural characteristics, however, plants of ‘WNHYDFBPBMH’ differ in the following:

    • 1. Inflorescences of the new variety are mophead, while inflorescences of this comparator are lacecap.
    • 2. Sepals of the new variety emerge greenish-white then stay pink or light blue for the duration of the inflorescence (depending upon soil pH and treatment). Sepals of this comparator emerge greenish-white then swiftly mature to white.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
