Description

Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘STRAMINI’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Hydrangea plant known by the varietal name ‘Stramini’. The new variety was discovered in 2006 in a planned breeding program in Harderwijk, The Netherlands. The purpose of the breeding program was to develop Hydrangeas with improved green-like flower colors. The new variety is the result of a cross between breeding selection Seedling 1012 (female parent, unpatented) and Seedling HY 2586 (male parent, unpatented). The compact nature of ‘Stramini’ is similar to its female parent, but it differs from Seedling 1012 in flower color. The flower color of ‘Stramini’ is similar to its male parent, but it differs from Seedling HY 2586 in leaf shape. Further, ‘Stramini’ exhibits greener colored flowers than Hydrangea plant ‘Elbtal’ (upatented). The new variety was first asexually reproduced in 2007 via propagation by cuttings in Harderwijk, The Netherlands. The new variety has been trial and field tested in Harderwijk, The Netherlands and has been found to retain its distinctive characteristics and remain true to type through successive propagations.

The following traits distinguish ‘Stramini’ as a new and distinct cultivar from other Hydrangea varieties known to the breeder:

    • 1. Multi colored flowers with a greenish hue; and
    • 2. Strong stems.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 is photograph of an entire plant of the new variety; and

FIG. 2 is another photograph of the same plant of the new variety of FIG. 1, whereby color differences are due to differences in the flowering stage of the plant.

 DESCRIPTION OF THE PLANT

The following detailed description sets forth characteristics of the new cultivar. The plants were grown in 15 cm. pots, 8 per m2, in ordinary potting soil with granulated fertilizers at a pH of 6.0. The plants were two years old when described. Measurements and color readings of the plants were taken in Harderwijk, The Netherlands under natural light.
