Abstract

A new and distinct Hydrangea cultivar named ‘STMS1’ is disclosed, characterized by a full, round mophead type inflorescence and deep pink petal with a creamy interior coloration and unique serrate petal margins. Plants are characteristically strong and resistant to breaking, and produce dark green foliage. The new variety is a Hydrangea, normally used for ornamental indoor or outdoor purposes.

Description

Latin name of the genus and species: Hydrangea macrophylla×serrata.
Variety denomination: ‘STMS1’.
BACKGROUND OF THE INVENTION
The new cultivar is a product of a planned breeding program. The intent of the breeder program was to develop Hydrangea varieties with strong stems and attractive flower colors. The new variety was discovered as seedling within the planned breeding program. This seedling is a result from the crossing of the female parent, an undistributed proprietary variety referred to as 9626 with the male parent, an undistributed proprietary variety referred to as 9659. It was selected by Daniel van der Spek in May of 2002 in Nootdorp, the Netherlands.
Asexual reproduction of the new cultivar ‘STMS1’ by vegetative cuttings was first performed in Nootdorp, the Netherlands during 2002 and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.
Asexual reproduction of the new cultivar ‘STMS1’ by vegetative cuttings was performed in Nootdorp, the Netherlands and has shown that the unique features of this cultivar are stable and reproduced true to type through 6 successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘STMS1’ 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 ‘STMS1’ These characteristics in combination distinguish ‘STMS1’ as a new and distinct Hydrangea cultivar:
    • 1. Full, round mophead inflorescence.
    • 2. Unique sepal coloration, creamy interior petal and deep pink margins.
    • 3. Dark green foliage.
    • 4. Strong plant, resisting breaking in production and post-harvest situations.
    • 5. Unique serration to sepal margins.
PARENTAL COMPARISON
Plants of the new cultivar ‘STMS1’ are similar to plants of the female parent, ‘9626’ in most horticultural characteristics, however, plants of the new cultivar ‘STMS1’ differ from ‘9626’ in the following characteristics;
    • 1. Flower color of ‘STMS1’ is white with a deep pink margin whereas ‘9626’ is solid light pink.
    • 2. ‘STMS1’ has more flowers per inflorescence.
    • 3. ‘STMS1’ has a wider inflorescence.
    • 4. ‘STMS1’ is a shorter plant than ‘9626’.
Plants of the new cultivar ‘STMS1’ are similar to plants of the male parent, ‘9659’ in most horticultural characteristics, however, plants of the new cultivar ‘STMS1’ differ from ‘9659’ in the following characteristics;
    • 1. Foliage color of ‘STMS1’ is darker than ‘9659’.
    • 2. ‘STMS1’ is a shorter plant.
    • 3. Flowers of ‘STMS1’ have a distinctive darker margin whereas ‘9659’ has solid color flowers.
COMMERCIAL COMPARISON
Plants of the new cultivar ‘STMS1’ are similar to plants of the commercial variety ‘Sidaseli’, U.S. Plant Pat. No. 20,124 in most horticultural characteristics. However, plants of the new cultivar ‘STMS1’ differ from ‘Sidaseli’ in producing an inflorescence that is a round, mophead, compared to the flattened lacecap of ‘Sidaseli’. Additionally, ‘STMS1’ produces flowers with a serrated margin to the sepal.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical flower of ‘STMS1’.
FIG. 2 shows a blooming plant of ‘STMS1’ grown in a greenhouse. 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.
