plant named ‘Oploo5’

Abstract

A new cultivar of Photinia, ‘Oploo5’, that is characterized by its bushy, loose, broad spreading, and upright plant habit, its young leaves that are grayed-red to grayed-orange in color and heavily marbled with yellow-green in unique patterns on all leaves, and its mature leaves that are marbled in various patterns with grayed-green, green and yellow-green.

Description

Botanical classification: Photinia serratifolia.

Variety denomination: ‘Oploo5’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Photinia serratifolia, and will be referred to hereafter by its cultivar name, ‘Oploo5’. ‘Oploo5’ is a new cultivar of evergreen shrub grown for use as a landscape plant.

The Inventor discovered the new cultivar in June of 2002 as a naturally occurring branch mutation of Photinia ‘Jenny’ (not patented) in a production container block at the Inventor's nursery in Bavel, The Netherlands.

Asexual reproduction of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in Bavel, The Netherlands in 2010. Asexual propagation by softwood stem cuttings has determined that the characteristics 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 ‘Oploo5’ as unique cultivar of Photinia.

• • 1. ‘Oploo5’ exhibits a bushy, loose, broad spreading, upright plant habit.
  • 2. ‘Oploo5’ exhibits young leaves that are grayed-red to grayed-orange in color and heavily marbled with yellow-green in unique patterns on all leaves.
  • 3. ‘Oploo5’ exhibits mature leaves that are marbled in various patterns with grayed-green, green and yellow-green.

‘Jenny’, the parent of ‘Oploo5’, differs from ‘Oploo5’ in having leaves that are solid green and not variegated. There are no cultivars of Photinia serratifolia with variegated foliage known to the Inventor. ‘Oploo5’ can also be compared to the Photinia×fraseri cultivars ‘Indian Summer’ (not patented) and ‘Cassini’ (U.S. Plant Pat. No. 15,160). ‘Indian Summer’ is similar to ‘Oploo5’ in having new growth that is orange in color, but differs from ‘Oploo5’ in having foliage that is non-variegated. ‘Cassini’ is similar to ‘Oploo5’ in having variegated leaves. ‘Cassini’ differs from ‘Oploo5’ in having longer internodes, in having young leaves that are bright red and pink in color, and in having mature leaves that have green centers and white margins.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrat the overall appearance and distinct characteristics of 3 year-old plants of the new Photinia as field grown outdoors in Bavel, The Netherlands.

The photograph is FIG. 1 provides a side view of the overall plant habit of ‘Oploo5’.

The photographs in FIG. 2 and FIG. 3 provide close-up views of the young foliage of ‘Oploo5’.

The photographs in FIG. 4 and FIG. 5 provide close-up views of mature foliage illustrating the variation in marbling of leaves of ‘Oploo5’.

The colors in the photographs are as close as possible with the digital photography techniques available and the color values cited in the detailed botanical description most accurately describe the colors of the new Photinia.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 3 year-old plants of the new Photinia as field grown in Bavel, The Netherlands (and placed in a container for the photographs).
