Abstract

A new cultivar of Hydrangea plant named ‘RIE 09’ that is characterized by broad upright habit, large dark grey-green leaves, flowers that range in color from yellow-green to light and dark pink, and unique inflorescence development. In combination these traits set ‘RIE 09’ apart from all other existing varieties of Hydrangea known to the inventor.

Description

Genus: Hydrangea.
Species: macrophylla.
Denomination: RIE 09.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of hydrangea that is grown for use as an indoor floral potted plant and an outdoor ornamental flowering shrub. The new cultivar is known botanically as Hydrangea macrophylla and will be referred to hereinafter by the cultivar name ‘RIE 09’.
‘RIE 09’ resulted from a breeding program that was conducted by the inventor at the inventor's nursery in Kyoto, Japan and began in 1990. The purpose of the breeding program was to produce new varieties of floral potted hydrangeas that exhibit new and unique flowers and flower color.
Between May 1990 and May 1993 the inventor assembled a collection of unnamed and unreleased hybrids from a sequence of deliberate pollinations involving the following cultivars, all unpatented, and available in commerce in Japan: Hydrangea macrophylla ‘Otafuku’, Hydrangea macrophylla, ‘Yamaajisai’, and Hydrangea macrophylla ‘Fijinishiritaki’. The inventor did not record which variety was used as male parent and which as female parent. In May 1993, the inventor carried out a deliberate pollination between one unnamed plant from the inventor's collection as female parent and the variety Hydrangea macrophylla ‘Sumidanohanabi’ (unpatented) as male parent.
The pollination described above produced thirty-five individual varieties, which the inventor considered novel and unusual. One of these individual varieties was selected by the inventor in June 1994 and is the subject of the present invention, ‘RIE 09’.
‘RIE 09’ is a deciduous shrub that exhibits large dark grey-green leaves and individual flowers that range in color from yellow-green to light and dark pink. Selection was based on the distinguishing characteristics of flowers, flower color, and inflorescence development. ‘Lace cap’ type hydrangeas produce showy sterile flowers along the outside of the inflorescence, and small inner flowers that are fertile flowers. When an individual inflorescence of ‘RIE 09’ first opens, it looks like a ‘lace cap’ type inflorescence with large sterile flowers on the edge. However, unlike the ‘lace cap’ type Hydrangea, the inflorescence eventually fills out completely. Within the inflorescence, center fertile flowers are intermixed with center sterile flowers, so that as the inflorescence develops further, the sterile flowers in the center open fully to then cover the smaller fertile flowers. ‘RIE 09’ is distinguishable from the parent plants by flower color, and unique inflorescence development, which produces an average of 150 sterile flowers and 400 fertile flowers per inflorescence.
The inventor considers that ‘RIE09’ is distinct from other varieties of Hydrangea known to the inventor in the following respects:
First, whereas other varieties of Hydrangea in commerce have four petals per floret on a flat, one-dimensional plane, ‘RIE 09’ has two to three layers of petals per floret, creating a double-flower appearance.
Second, whereas many novel varieties have been found in, or brought from, Japan in recent years, none appear to have the combination of uniqueness of flower form as above combined with greater vigor and faster growing to flowering stage which typifies ‘RIE 09’.
Third, the vigor of ‘RIE 09’ is evident in its strong thick stems which do not require staking to support the heavy blooms. ‘RIE 09’, although vigorous, exhibits a shorter internode distance than many other commercial forms of Hydrangea, allowing ‘RIE 09’ to be grown commercially with less or even no application of growth regulating chemical.
‘RIE 09’ was first asexually propagated by the inventor, in the spring of 1995 in a cultivated area of Kyoto, Japan. The method used for asexual propagation was softwood cuttings. The characteristics of the new Hydrangea cultivar named ‘RIE 09’ have been determined stable and are reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new Hydrangea cultivar ‘RIE 09’. These traits in combination distinguish ‘RIE 09’ from all other commercial varieties of Hydrangea known to the inventor. ‘RIE 09’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, without however, any difference in genotype.

BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new Hydrangea cultivar ‘RIE 09’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety of Hydrangea named ‘RIE 09’.
The drawing labeled as FIG. 1 depicts an individual whole plant growing in a 1.5-liter container in a frost-protected greenhouse in De Kwakel, The Netherlands. The plant is approximately twenty one months old. The plant was produced from a cutting which was rooted and grown in a four inch container, then transplanted into the 1.5 liter container, then pinched to encourage basal branching, then allowed to shoot from the base and allowed to flower in its natural season. The plant was pruned back to the base after flowering. The drawing depicts the vigorous basal branching habit of ‘RIE 09’ in its second season of re-growth. Such a plant would be highly suitable for use as a stock plant for the purpose of providing cutting material for commercial propagation.
The drawing labeled as FIG. 2 illustrates a one year old plant of ‘RIE 09’ which has been grown in a 1.5 liter container in a frost-protected greenhouse in De Kwakel, The Netherlands. The plant was produced from a cutting which was rooted and grown in a four inch container, then transplanted into the 1.5 liter container and pinched to encourage basal branching. Three branches arose and were allowed to flower. This drawing depicts the inflorescence of ‘RIE 09’ at three developmental stages, from first opening of an individual sterile flower to full development of the sterile flowers which are held above, and covering, the smaller fertile flowers.
The drawing labeled FIG. 3 illustrates the inflorescence of ‘RIE09’, in which the center fertile flowers are intermixed with center sterile flowers. This drawing depicts the inflorescence at the stage when the sterile flowers are almost all developed and covering the smaller fertile flowers.
All drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible, by conventional photography.
 BOTANICAL DESCRIPTION OF THE PLANT
The following is the detailed description of ‘RIE 09’ as grown in a greenhouse in De Kwakel, The Netherlands. Data was collected in April 2004 from 12-month-old plants grown in 1.5-liter containers.
