Hebe plant named ‘Tulpink’

Abstract

A new cultivar of Hebe, ‘Tulpink’, characterized by its compact and rounded plant habit, its foliage that is dark green with a thin red margin and red midrib, its cerise pink flowers and its ability to consistently produce healthy plants.

Description

Botanical classification: Hebe hybrid.

Cultivar designation: ‘Tulpink’.

BACKGROUND OF THE INVENTION

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

The new cultivar was selected as a seedling that arose from the open pollination of unnamed proprietary Hebe plants (not patented) from the Inventor's breeding program growing in a trial garden in the Inventor's nursery in summer of 2007 in Ballyboughal, Dublin County, Ireland. The parentage is unknown as seeds had been collected and sown from many female plants.

Asexual propagation of the new cultivar was first accomplished by the Inventor by softwood cuttings in Ballyboughal, Dublin County, Ireland in summer of 2007. Asexual propagation by softwood stem cuttings has been 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, which in combination distinguish ‘Tulpink’ as a new and distinct cultivar of Hebe.

• • 1. ‘Tulpink’ exhibits a compact and rounded plant habit.
  • 2. ‘Tulpink’ exhibits foliage that is dark green with a thin red margin and red midrib.
  • 3. ‘Tulpink’ exhibits cerise pink flowers.
  • 4. ‘Tulpink’ consistently produces healthy plants.

‘Tulpink’ can be most closely compared to the cultivars ‘Inspiration’ and ‘Wiri Charm’ (both un-patented). ‘Inspiration’ differs from ‘Tulpink’ in having a more upright plant habit, in having foliage that is lighter green in color and narrower, in having flowers that are mauve pink, and in being taller in height. ‘Wiri Charm’ differs from ‘Tulpink’ in having foliage that is narrower, longer, and lighter green in color, in having a more vigorous growth habit, and in having a taller and more upright plant habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hebe. The photographs were taken of a plant approximately five years in age as field grown in Stroe, The Netherlands.

The photograph in FIG. 1 is a side view of ‘Tulpink’.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Tulpink’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Tulpink’.

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 five year-old plants of the new cultivar as field grown in Stroe, The Netherlands. Plants were grown under average day temperatures of 10° to 28° C. and average night temperatures of 4° to 16° C. 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 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
