Abstract

A new and distinct Hydrangea cultivar named ‘SMHMEPSILON’ is disclosed, characterized by lace-cap inflorescence, early flowering and strong, continuous blooming. The new variety is a Hydrangea, normally produced as an ornamental plant for containers or gardens.

Description

Latin name of the genus and species: Hydrangea hybrid.
Variety denomination: ‘SMHMEPSILON’.
BACKGROUND OF THE INVENTION
The new Hydrangea cultivar is a product of a planned breeding program conducted by the inventor, Timothy D. Wood, in Grand Haven, Mich. The objective of the breeding program was to produce new Hydrangea varieties. The open pollination resulting in this new variety was made during July of 2008.
The seed parent is the patented commercial variety Hydrangea macrophylla ‘Robert’ U.S. Plant Pat. No. 20,020. The pollen parent is unknown, as it was an open pollination breeding program. The new variety was identified as a potentially interesting selection in June of 2011, at a greenhouse in Grand Haven, Mich.
Asexual reproduction of the new cultivar ‘SMHMEPSILON’ by softwood cuttings was first performed during the June of 2011, at commercial greenhouse in Grand Haven, Mich. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in 4 successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘SMHMEPSILON’ 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 ‘SMHMEPSILON’ These characteristics in combination distinguish ‘SMHMEPSILON’ as a new and distinct Hydrangea cultivar:
    • 1. Lace-cap inflorescence.
    • 2. Early flowering.
    • 3. Strong continuous bloomer.
PARENT COMPARISON
Plants of the new cultivar ‘SMHMEPSILON’ are similar to plants of the seed parent, Hydrangea macrophylla ‘Robert’ in most horticultural characteristics, however, plants of the new cultivar ‘SMHMEPSILON’ differ in the following:
    • 1. Lacecap inflorescence. Seed parent has a mophead inflorescence.
    • 2. Earlier flowering
    • 3. Stronger flowering stems.
Pollen parent unknown as this is product of open pollination.
COMMERCIAL COMPARISON
‘SMHMEPSILON’ can be compared to the patented commercial variety Hydrangea ‘MAK20’ U.S. Plant Pat. No. 24,820. These varieties are similar in most horticultural characteristics; however ‘SMHMEPSILON’ differs in the following:
    • 1. Taller plant.
    • 2. Larger inflorescence width.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical flowering plant of ‘SMHMEPSILON’ grown outdoors in Grand Haven, Mich., USA, in a field.
FIG. 2 illustrates in full color a close up view of the inflorescence. Inflorescences on the plant in FIG. 1 are less mature than those in FIG. 2. Age of the plant photographed is approximately 2-3 years.
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.
