plant named ‘Golden Glow’

Abstract

A new cultivar of Lonicera, ‘Golden Glow’, that is characterized by its compact, well branched, and creeping plant habit, its foliage that is intense golden yellow in color that does not burn when grown under intense sun and hot temperatures, and its leaves that are ovate to narrow ovate in shape.

Description

Botanical classification: Lonicera nitida.

Variety denomination: ‘Golden Glow’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lonicera nitida and will be referred to hereafter by its cultivar name, ‘Golden Glow’. ‘Golden Glow’ is a new cultivar of boxleaf honeysuckle, an evergreen shrub grown for use as an ornamental landscape plant.

The Inventor discovered the new cultivar in spring of 2008 as a naturally occurring branch mutation of Lonicera nitida ‘Maigrün’ (not patented) in a container block at his nursery in Harfsen, The Netherlands.

Asexual propagation of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 2008 in Harfsen, The Netherlands. Asexual propagation by softwood 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 ‘Golden Glow’ as a unique cultivar of Lonicera.

• • 1. ‘Golden Glow’ exhibits a compact, well branched, and creeping plant habit.
  • 2. ‘Golden Glow’ exhibits foliage that is intense golden yellow in color that does not burn when grown under intense sun and hot temperatures.
  • 3. ‘Golden Glow’ exhibits leaves that are ovate to narrow ovate in shape.

The parent plant, ‘Maigrün’, differs from ‘Golden Glow’ in having foliage that is light green in color. In addition, ‘Golden Glow’ can be compared to Lonicera nitida cultivars ‘Baggesen's Gold’ and ‘Lemon Beauty’ (both not patented). ‘Baggesen's Gold’ is similar to ‘Golden Glow’ in foliage coloration, but differs from ‘Golden Glow’ in having an upright plant habit and in leaves that are smaller and round to broadly ovate in shape. ‘Lemon Beauty’ is similar to ‘Golden Glow’ in plant habit, but differs from ‘Golden Glow’ in having variegated leaves with green centers and golden yellow to cream colored margins.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Lonicera. The photographs were taken of a plant two years in age as field grown outdoors in Harfsen, The Netherlands and placed in a one-gallon container for the photographs.

The photograph in FIG. 1 provides a side view of ‘Golden Glow’ and illustrates its plant habit.

The photograph in FIG. 2 provides a close-up view of the foliage of ‘Golden Glow’.

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 Lonicera.
