tree named ‘Woodside Splendor’

Abstract

A new cultivar of Quercus, ‘Woodside Splendor’, that is characterized by its relatively narrow plant habit and its autumn foliage coloration that is deep red in color and appears early in the season and is retained for a long period of time.

Variety denomination: ‘Woodside Splendor’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to a European plant breeders' rights application filed on Apr. 23, 2012, application No. 2012/0872. There have been no offers for sale anywhere in the world prior to the filing of this Application and no accessibility to one of ordinary skill in the art could have been derived from printed plant breeder's rights documents.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Quercus palustris, and will be referred to hereafter by its cultivar name, ‘Woodside Splendor’. ‘Woodside Splendor’ is a deciduous tree grown for use as a landscape plant.

The Inventors selected the new cultivar, ‘Woodside Splendor’, as a seedling in Sint-Oedenrode, Netherlands in the September of 1996. The seedbed had been planted with seeds collected from an unnamed and unpatented open pollinated plants of Quercus palustris.

Asexual reproduction of the new cultivar was first accomplished by grafting onto Quercus palustris by the Inventor in Sint-Oedenrode, Netherlands in September of 1996. Asexual propagation of ‘Woodside Splendor’ by grafting has shown that the unique features of the new cultivar are 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 ‘Woodside Splendor’ as a new and unique cultivar of Quercus.

• • 1. ‘Woodside Splendor’ exhibits a relatively narrow plant habit.
  • 2. ‘Woodside Splendor’ exhibits autumn foliage coloration that is deep red in color and appears early in the season and is retained for a long period of time.

The parent of ‘Woodside Splendor’ differs from ‘Woodside Splendor’ in having a broader plant habit and in having autumn foliage coloration that appears later in the season, is lighter in color and not retained as late in the season. ‘Woodside Splendor’ can also be compared to Quercus palustris cultivars ‘Pringreen’ (U.S. Plant Pat. No. 9,093) and ‘Helmonds Red Globe’ (not patented). ‘Pringreen’ is similar to ‘Woodside Splendor’ in having an upright plant shape. ‘Pringreen’ differs from ‘Woodside Splendor’ in having a broader plant habit and in having autumn foliage coloration that appears later in the season, is lighter in color and not retained as late in the season. ‘Helmonds Red Globe’ is similar to ‘Woodside Splendor’ in having foliage with deep colored foliage in autumn that is retained late in the season. ‘Helmonds Red Globe’ differs from ‘Woodside Splendor’ in having a broader plant habit when mature and in having autumn foliage coloration that appears later in the season.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Quercus, ‘Woodside Splendor’. The photographs were taken of a 19 year-old tree of ‘Woodside Splendor’ as grown outdoors in a trial plot in Sint-Oedenrode, Netherlands.

FIG. 1 provides an overall view of the foliage and plant habit of ‘Woodside Splendor’ in fall.

The photograph in FIG. 2 provides a close-up view of the fall foliage of ‘Woodside Splendor’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Quercus.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of a 19-year old plant of the new cultivar as grown outdoors in a trial plot in Sint-Oedenrode, Netherlands.

The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
