plant named ‘Jewel of the Nile’

Abstract

A new cultivar of Hebe, ‘Jewel of the Nile’, characterized by its variegated leaves with olive green centers and yellow margins that are tinged with purple, its long narrow leaves with midribs on the upper and lower surface purple in color, its young leaves that are tinged with mauve purple at the leaf base, its purple stems, its that are resistant to leaf spot, and its mauve pink flowers.

Description

Botanical classification: Hebe hybrid.

Cultivar designation: ‘Jewel of the Nile’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hebe, botanically of hybrid origin and in the group Comm. ex Juss. and known as Hebe ‘Jewel of the Nile’ and will be referred to hereafter by its cultivar name, ‘Jewel of the Nile’. ‘Jewel of the Nile’ is grown for use as a container plant and as a landscape shrub.

The new cultivar was discovered as a unique seedling in the Inventor's nursery in summer of 2010 in Cambridge, New Zealand. The new cultivar resulted from open pollination of an unnamed and unpatented Hebe plant in the Inventors breeding program in a trial plot planted with a collection of Hebe grown from seed. The male parent is therefore unknown.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using terminal stem cuttings in Cambridge, New Zealand in 2010. It has been determined that the characteristics of this 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, which in combination distinguish ‘Jewel of the Nile’ as a new and distinct cultivar of Hebe.

• • 1. ‘Jewel of the Nile’ exhibits variegated leaves with olive green centers and yellow margins that are tinged with purple.
  • 2. ‘Jewel of the Nile’ exhibits long narrow leaves.
  • 3. ‘Jewel of the Nile’ exhibits leaves with the midrib on the upper and lower surface purple in color.
  • 4. ‘Jewel of the Nile’ exhibits young leaves that are tinged with mauve purple at the leaf base.
  • 5. ‘Jewel of the Nile’ exhibits stems that are purple in color.
  • 6. ‘Jewel of the Nile’ exhibits leaves that are resistant to leaf spot.
  • 7. ‘Jewel of the Nile’ exhibits mauve pink flowers.

‘Jewel of the Nile’ differs from its seed plant in having brighter and clearer leaf colors, more distinct purple coloration on the stems and leaf veins, more distinct yellow margins, and increases resistance to leaf spot. ‘Jewel of the Nile’ can be most closely compared to the cultivars ‘Grace Kelly’ (U.S. Plant Pat. No. 22,653) and ‘Orphan Annie’ (not patented). ‘Grace Kelly’ differs from ‘Jewel of the Nile’ in having variegated foliage that has lighter yellow margins, in having less purple coloration on the stems, leaf base, and leaf veins, in having less elongated leaves, and in having darker colored flowers. ‘Orphan Annie’ differs from ‘Jewel of the Nile’ in having new leaf tips that are tinged with magenta rather than yellow, and in having less intense purple coloration on the stems, leaf base, and leaf veins.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hebe. The photographs were taken of a plant approximately one year in age as grown in an 18-cm container outdoors in Cambridge, New Zealand.

The photograph in FIG. 1 is a top view of ‘Jewel of the Nile’ just beginning to bloom.

The photograph in FIG. 2 provides a close-up view of the inflorescences and leaves of ‘Jewel of the Nile’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Hebe.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT
