USPP20868P2 - Hebe plant named ‘Silver Lady’ - Google Patents

Abstract

A new cultivar of Hebe, ‘Silver Lady’, characterized by its variegated foliage with olive-gray green centers and thin creamy white margins and its newly emerging leaves with a lower surface that is deep mauve-purple in color.

Description

Botanical classification: Hebe hybrid.

Cultivar designation: ‘Silver Lady’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hebe, botanically of hybrid origin and known as Hebe ‘Silver Lady’ and will be referred to hereafter by its cultivar name, ‘Silver Lady’. ‘Silver Lady’ is grown for use as a container plant and as a landscape shrub.

The new cultivar was discovered as a branch mutation of the cultivar ‘Orphan Annie’ (non patented) in a container in the Inventor's nursery in September of 2005 in Cambridge, New Zealand.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using terminal stem cuttings in Cambridge, New Zealand, in October 2005. 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 ‘Silver Lady’ as a new and distinct cultivar of Hebe.

• • 1. ‘Silver Lady’ exhibits foliage in which the lower surface of the newly emerging leaves is deep mauve-purple in color.
  • 2. ‘Silver Lady’ exhibits leaves that are variegated with olive gray-green centers and thin creamy white margins.

‘Silver Lady’ can be most closely compared to ‘Orphan Annie’, the parent plant. ‘Orphan Annie’ differs from ‘Silver Lady’ in having leaves that are lighter green in color, and in having leaf margins that are wider, more cream colored, and that occasionally extend into the leaf centers. ‘Silver Lady’ can also be compared to ‘Lady Ann’ (not patented). ‘Lady Ann’ has wider leaf margins that extends into the leaf centers and ‘Lady Ann’ also develops into a larger sized plant.

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 twelve months in age as grown outdoors in a 18 cm container in Auckland, New Zealand.

The photograph in FIG. 1 provides a side view of ‘Silver Lady’ and

the photograph in FIG. 2 provides a close-up view of the spring foliage of ‘Silver Lady’.

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

The following is a detailed description of twelve month-old plants of the new cultivar as grown outdoors in 18 cm containers in Auckland, New Zealand.

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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
