Description

Genus/species: Hydrangea paniculata.

Varietal denomination: ‘WIMS RED’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea macrophylla and will be referred to hereafter by its cultivar name, ‘WIMS RED’. ‘WIMS RED’ represents a new panicle hydrangea, a deciduous shrub grown for landscape use.

‘WIMS RED’ arose as part of an ongoing breeding program by the Inventor in Leende, The Netherlands with the goal of developing a new cultivar of panicle hydrangea with strong stems and inflorescences that change in color from white to red. ‘WIMS RED’ originated from a cross made in 2001 between ‘Pink Diamond’ (not patented) as the female parent and ‘Dharuma’ (not patented) as the male parent. The new Hydrangea was selected as a unique single plant from the progeny of the above cross in 2004.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings in Rijkevorsel, Belgium in 2006 under the direction of the Inventor. Asexual propagation by softwood stem cuttings and tissue culture has shown that the characteristics of this cultivar are stable and 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 cultivar. These attributes in combination distinguish ‘WIMS RED’ as a unique cultivar of Hydrangea paniculata.

    • 1. ‘WIMS RED’ exhibits inflorescences that emerge white in color and change to pink and finally turning red in early fall.
    • 2. ‘WIMS RED’ exhibits long panicle type inflorescences that are broadly conical in shape.
    • 3. ‘WIMS RED’ exhibits strong stems that are red-brown in color.
    • 4. ‘WIMS RED’ blooms from summer to early autumn in The Netherlands.
    • 5. ‘WIMS RED’ is heat and shade tolerant.

Pink Diamond’, the female parent of ‘WIMS RED’, differs from ‘WIMS RED’ in having inflorescences with sterile florets that emerge white with pink centers and turn bright pink as they mature. ‘Dharuma’, the male parent of ‘WIMS RED’, differs from ‘WIMS RED’ in having inflorescences with sterile florets that emerge white and turn pink as they mature and in having a more compact plant habit. ‘WIMS RED’ can also be compared to the cultivar ‘Early Sensation’(not patented), which is similar in having inflorescences that emerge white and turn to red when mature and in having strong red-brown stems. ‘Early Sensation’ differs from ‘WIMS RED’ in having foliage that is darker in color, and in having inflorescences that are smaller and less conical in shape.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Hydrangea. The plant in the photograph is about three years in age as grown outdoors in a garden in Rijkevorsel, Belgium.

The photograph in FIG. 1 provides a view of an inflorescence of ‘WIMS RED’ in early summer.

The photograph in FIG. 2 provides a view of an inflorescence of ‘WIMS RED’ in mid summer.

The photograph in FIG. 3 provides a view of an inflorescence of ‘WIMS RED’ in fall.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Hydrangea.
