Description

Botanical classification: Hypericum×inodorum.

Variety denomination: ‘Ruihyh006b’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypericum×inodorum and will be referred to hereafter by its cultivar name, ‘Ruihyh006b’. ‘Ruihyh006b’ is a semi-evergreen shrub grown for use as a landscape plant and container plantings.

The new cultivar was derived from a controlled breeding program conducted by the Inventor in Hazerswoude, The Netherlands. The overall purpose of the breeding program was to develop new cultivars of Hypericum plants with different shapes and sizes of berries and with resistance to Melampsora hypericorum.

The new cultivar arose from a cross made by the Inventor in Hazerswoude, The Netherlands in April 2007 between ‘White Hypearl’ (not patented) as the female parent and ‘Jolly Hypearl’ (not patented) as the male parent. The Inventor selected ‘Ruihyh006b’ as a single unique plant amongst the seedlings that resulted from the above cross in autumn of 2008.

Asexual propagation of the new cultivar was first accomplished by the Inventor by vegetative stem cuttings in 2010 in Hazerswoude, The Netherlands. Asexual propagation by vegetative 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 ‘Ruihyh006b’ as a unique cultivar of Hypericum.

    • 1. ‘Ruihyh006b’ exhibits a compact plant habit suitable for container growing.
    • 2. ‘Ruihyh006b’ exhibits medium sized berries that are light orange-pink in color and round in shape.
    • 3. ‘Ruihyh006b’ exhibits small sized, light green sepals.

The female parent of ‘Ruihyh006b’, ‘White Hypearl’, differs from ‘Ruihyh006b’ in having berries that are white in color. The male parent of ‘Ruihyh006b’, ‘Jolly Hypearl’, differs from ‘Ruihyh006b’ in having berries that are red in color, narrower in width, and longer in length. ‘Ruihyh006b’ can be most closely compared to the cultivar ‘Hot Hypearl’ (not patented). ‘Hot Hypearl’ is similar to ‘Ruihyh006b’ in having berries that are rounded in shape. ‘Hot Hypearl’ differs from ‘Ruihyh006b’ in having berries that are red 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 plants two years in age as grown in a one-gallon container in a greenhouse in Lelystad, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘Ruihyh006b’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘Ruihyh006b’.

The photograph in FIG. 3 provides a close-up view of the berries of ‘Ruihyh006b’.

The colors in the photographs are as close as possible with the digital photography techniques available, 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 two year-old plants of the new cultivar as grown outdoors in 2-gallon containers in Davidsonville, Md. 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.
