Description

Botanical classification: Berberis thunbergii.

Cultivar designation: ‘Golden Dream’.

RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent applications filed for cultivars derived from the same breeding program entitled Berberis Plant Named ‘Orange Dream’ (U.S. Plant patent application Ser. No. 13/506,333) and Berberis Plant Named ‘Red Dream’ (U.S. Plant patent application Ser. No. 13/506,332).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Berberis thunbergii, and will be referred to hereafter by its cultivar name, ‘Golden Dream’. ‘Golden Dream’ is grown for use as a landscape shrub.

The new cultivar arose through an ongoing breeding project by the Inventor in Litomysl, Czech Republic with the objective of selecting new and unique cultivars of Berberis. ‘Golden Dream’ arose from open pollination in 2003 of an unnamed plant of Berberis thunbergii from the Inventors breeding program as the female parent. ‘Golden Dream’ was selected as a single unique plant from the resulting seedlings in 2005.

Asexual reproduction of the new cultivar was first accomplished by the Inventor by softwood stem cuttings in Litomysl, Czech Republic in 2007. 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 ‘Golden Dream’ as a new and distinct cultivar of Berberis.

    • 1. ‘Golden Dream’ exhibits small sized leaves.
    • 2. ‘Golden Dream’ exhibits foliage that is yellow-green in color.
    • 3. ‘Golden Dream’ exhibits a moderately compact plant habit with upright branches.

The female parent of ‘Golden Dream’ differs from ‘Golden Dream’ in having dark green leaves, a more open growth habit, and broader and larger leaves. ‘Golden Dream’ can be most closely compared to the cultivars ‘Orange Dream’, ‘Red Dream’ ‘Admiration’ (U.S. Plant Pat. No. 16,921), and ‘Aures’ (not patented). ‘Orange Dream’ differs from ‘Golden Dream’ in having gray-purple to brown leaves, a less compact plant habit, and branches that are arching. ‘Red Dream’ differs from ‘Golden Dream’ in having leaves that are brown in color, a less compact plant habit, and branches that are arching. ‘Admiration’ differs from ‘Golden Dream’ in having broader larger leaves that are gray-purple to orange-brown in color with thin yellow-green margins and in having an even more dense compact plant habit. ‘Aurea’ differs from ‘Golden Dream’ in having yellow leaves and an even more dense compact plant habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Berberis. The photographs were taken of a plant two years in age as grown in a one-gallon container in Helden, The Netherlands.

The photograph in FIG. 1 provides a view of the plant habit of ‘Golden Dream’ and the photograph in FIG. 2 provides a close-up view of the foliage of ‘Golden Dream’. 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 Berberis.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of two year-old plants of the new cultivar as grown in one-gallon containers in Helden, The Netherlands. Plants were grown under average day temperatures of 15° C. and average night temperatures of 10° 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.
