The present invention relates to a new and distinct cultivar 5

of Hydrangea paniculala and will be referred to hereafter by

deciduous shrub grown for landscape use. The new Hydrangea resulted from a controlled breeding program that commenced in 1987 in Gorron, France with the

plished by softwood cuttings in May of 2003 by the inven tors in Gorron, France. The characteristics of this cultivar have been determined to be stable and are reproduced true to 25

The following traits have been repeatedly observed and represent the characteristics of the new cultivar as observed

for 5 years in Gorron, France. These attributes in combina

tion distinguish in ‘RENHY’ from other varieties of Hydran gea known to the inventor.

1. ‘RENHY’ blooms with large panicles of ?owers that emerge white in mid summer, changing to pink after about 2 weeks and subsequently change to red or bur gundy (depending on night temperature). The red col

turn light pink in late summer rather than red, some of the ?owers are fertile, and the plant habit is very erect. ‘RENHY’ can also be compared to ‘Grandi?ora’ (not

patented) and ‘Pinky Winky’ (not patented). ‘Grandi?ora’

type in successive generations. SUMMARY OF THE INVENTION

Comparison to other Hydrangea paniculala cultivars: ‘Unique’, the parent of the parent plants of ‘RENHY’, is similar in having large white ?owers, however the ?owers

also has large white ?owers, however they are all fertile ?owers and the ?owers are pink for only a short period time. ‘Pinky Winky’ also has white ?owers that are pink and red for only a short period of time and has a habit that is more erect than ‘RENHY’. BRIEF DESCRIPTION OF THE DRAWINGS

The drawings presented are digital photographs taken of plants 5 years in age in Gorron, France. FIG. 1 is a side view of ‘RENHY’ in early fall and shows the multicolored effect of the in?orescences and the deep red coloration of mature ?owers.

US PP20,67O P3 3 FIG. 2 is a side vieW of ‘RENHY’ and presents the color of the in?orescences in late summer While FIG. 3 depicts the color of the in?orescences in mid summer during the ?rst ?ush of bloom. A close-up vieW of an in?orescence in late summer is

depicted in FIG. 4. The colors in the photographs are as close as possible With

the photographic and printing technology utiliZed. The color values cited in the detailed botanical description accurately describe the colors of the neW Hydrangea. BOTANICAL DESCRIPTION OF THE PLANT

The folloWing is a detailed description of the neW cultivar as observed on plants groWn outdoors in a trial garden for 5 years in Gorron, France and of plants tWo years in age as
