plant named ‘Kolpeke’

Abstract

A new cultivar of Hypericum plant named ‘Kolpeke’ that is characterized by its leaves that are small in size and healthy, its large sized berries that are light orange-pink in color, and its branches that are held upright.

Description

Botanical classification: Hypericum x inodorum.

Variety denomination: ‘Kolpeke’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypericum x inodorum and will be referred to hereafter by its cultivar name, ‘Kolpeke’. ‘Kolpeke’ is a semi-evergreen shrub grown for use as a landscape plant and for container plantings.

The new cultivar was derived from a controlled breeding program conducted by the Inventor in Heelsum, The Netherlands. The overall purpose of the breeding program was to develop new cultivars of Hypericum plants with unique berry colors and healthy foliage.

The new cultivar arose from a cross made by the Inventor in Heelsum, The Netherlands in June of 2012 between an unnamed plant from the Inventor's breeding program, accession No. 11148-02, as the female parent and accession No. 11101-11 as the male parent. The Inventor selected ‘Kolpeke’ as a single unique plant amongst the seedlings that resulted from the above cross in August of 2014.

Asexual propagation of the new cultivar was first accomplished by the Inventor by stem cuttings in August of 2014 in Boskoop, The Netherlands. Asexual propagation by 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 ‘Kolpeke’ as a unique cultivar of Hypericum.

• • 1. ‘Kolpeke’ exhibits leaves that are small in size and healthy.
  • 2. ‘Kolpeke’ exhibits large sized berries that are light orange-pink in color.
  • 3. ‘Kolpeke’ exhibits branches that are held upright.

The female parent of ‘Kolpeke’ differs from ‘Kolpeke’ in having berries that are less orange in color and in being less branched. The male parent of ‘Kolpeke’, differs from ‘Kolpeke’ in having berries that are less orange in color and more berries per branch. ‘Kolpeke’ can be most closely compared to the cultivars ‘Coco Casino’ (not patented) and ‘Coco Yoko’ (not patented). ‘Coco Casino’ and ‘Coco Yoko’ are both similar to ‘Kolpeke’ in having leaves that are green in color and branches that are brown-green in color. ‘Coco Casino’ differs from ‘Kolpeke’ in having berries that are more pink in color and ‘Coco Yoko’ differs from ‘Kolpeke’ in having berries that are more peach in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hypericum. The plants in the photographs were taken of a plant eight months in age as grown outdoors in a one-gallon container in a greenhouse in Redmond, Wash.

The photograph in FIG. 1 provides a side view of ‘Kolpeke’ with flower buds.

The photograph in FIG. 2 provides a close-up view of a flower and an immature, mature, and aged berries of ‘Kolpeke’.

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 accurately describe the colors of the new Hypericum.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of eight-month-old plants of the new cultivar as grown in a greenhouse in 1-gallon containers in Redmond, Wash. 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 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
