Abstract

A new cultivar of Hydrangea anomala subsp. petiolaris named ‘Silver Lining’ that is characterized by its variegated foliage with green centers and white margins, its stems that are brownish-orange in color when mature and its leaf buds that are light green in color.

Description

Genus/species: Hydrangea anomala subsp. petiolaris.

Varietal denomination: ‘Silver Lining’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea anomala subsp. petiolaris and will be referred to hereafter by its cultivar name, ‘Silver Lining’. ‘Silver Lining’ represents a new climbing Hydrangea grown for landscape use.

The Inventor discovered the new cultivar in 2005 as a naturally occurring branch mutation of Hydrangea anomala subsp. petiolaris ‘Firefly’ (U.S. Plant Pat. No. 11,038, also known as ‘Miranda’) that was growing in a container at his nursery in Boskoop, The Netherlands.

Asexual reproduction of the new cultivar was first accomplished by softwood stem cuttings in Boskoop, The Netherlands in 2006 by the Inventor. The characteristics of this cultivar have been determined to be 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 cultivar. These attributes in combination distinguish ‘Silver Lining’ as a unique cultivar of Hydrangea.

- 1. ‘Silver Lining’ exhibits variegated foliage with green centers and white margins.
- 2. ‘Silver Lining’ exhibits stems that are brownish-orange in color when mature.
- 3. ‘Silver Lining’ exhibits leaf buds that are light green in color.

‘Firefly’, the parent plant of ‘Silver Lining’ differs from ‘Silver Lining’ in having foliage that is variegated with green centers and golden yellow margins. The new cultivar of Hydrangea can be most closely compared to other cultivars of Hydrangea anomala subsp. petiolaris which are similar to ‘Silver Lining’ in having uniquely colored foliage; ‘Kuga Vareigated’ (U.S. Plant Pat. No. 13,247), ‘Kasai’ (U.S. Plant Pat. No. 13,845), and ‘Buttercup’ (not patented). ‘Kuga Vareigated’ differs from ‘Silver Lining’ in having foliage that is speckled green and white. ‘Kasai’ differs from ‘Silver Lining’ in having foliage that emerges white with green stippling and becomes green with white margins and some white stippling. ‘Buttercup’ differs from ‘Silver Lining’ in having foliage that is non-variegated and yellow in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographs were taken of a one year-old plant of ‘Silver Lining’ as grown outdoors in a 17-cm container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side-view of a plant of ‘Silver Lining’.

The photograph in FIG. 2 provides a close-up view of a leaf of ‘Silver Lining’.

The photograph in FIG. 3 provides a close-up view of an inflorescence of ‘Silver Lining’ (only fertile flowers are open).

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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of one year-old plants as grown in 17-cm containers outdoors in Boskoop, The Netherlands. The plants were grown under average day temperatures of 14° C. to 28° C. and average night temperatures of 8° C. to 17° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
