Abstract

A new and distinct cultivar of Hydrangea plant named ‘WNHYDFBLAMH’ is disclosed, characterized by mophead inflorescences, emerging from both terminal and lateral buds. Sepals emerge greenish-white then stay pink (basic soil conditions) or light blue (acidic soil conditions) for the duration of inflorescence. 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: ‘WNHYDFBLAMH’.
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, ‘Deep Purple’, 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 ‘WNHYDFBLAMH’ 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 ‘WNHYDFBLAMH’ 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 ‘WNHYDFBLAMH.’ These characteristics in combination distinguish ‘WNHYDFBLAMH’ 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 (basic soil) or light blue (acidic soil) for the duration of inflorescence.
    • 3. Cascading/trailing type habit.
    • 4. Leaf shape and size is more narrowly elliptic than Hydrangea macrophylla but larger than Hydrangea luteovenosa.
PARENT COMPARISONS
Plants of ‘WNHYDFBLAMH’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of ‘WNHYDFBLAMH’ 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 on only terminal buds.
    • 3. Plants of the new variety flower earlier than plants of the seed parent.
    • 4. Plants of the new variety have a weeping, cascading habit, while plants of the seed parent have an upright habit.
Plants of ‘WNHYDFBLAMH’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of ‘WNHYDFBLAMH’ differ in the following:
    • 1. Leaves of the new variety are medium-sized, while leaves of the pollen parent are small.
    • 2. Sepals of the new variety are larger than sepals of the pollen parent.
    • 3. Inflorescences of the new variety are mophead, while inflorescences of the pollen parent are lacecap.
COMMERCIAL COMPARISONS
Plants of the new cultivar Hydrangea ‘WNHYDFBLAMH’ can be compared to the commercial variety Hydrangea ‘USHYD0405’, U.S. Plant Pat. No. 31,120. Plants of ‘WNHYDFBLAMH’ are similar to plants of ‘USHYD0405’ in most horticultural characteristics, however, plants of ‘WNHYDFBLAMH’ differ in the following:
    • 1. Inflorescences of the new variety are mophead, while inflorescences of this comparator are lacecap.
    • 2. Flowers of the new variety open greenish-white then stay pink and light blue for duration of inflorescence. Flowers of this comparator open and remain white.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘WNHYDFBLAMH’ grown in a poly-greenhouse in Grand Haven, Michigan. This plant is approximately 2-3 years old, grown in a 2-gallon container and has been grown in acidic soil.
FIG. 2 illustrates in full color a close up of a mature inflorescence of ‘WNHYDFBLAMH’ given acidic treatment.
FIG. 3 illustrates in full color a typical plant of ‘WNHYDFBLAMH’ grown in a poly-greenhouse in Grand Haven that has been grown in basic soil conditions.
FIG. 4 illustrates in full color a typical plant in basic soil conditions of ‘WNHYDFBLAMH’ with mature inflorescences, more mature than that of FIG. 3 . The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
