Abstract

A new and distinct cultivar of Berberis plant named ‘AMERA’, characterized by its relatively compact, upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; leaves that are initially yellow green in color with orange red-colored margins becoming darker yellow green in color with development; and good garden performance.

Description

Botanical designation: Berberis thunbergii.

Cultivar denomination: ‘AMERA’.

Title: Berberis Plant Named ‘ARLENE’

Applicant: Timothy D. Wood

Ser. No. 16/350,428

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Berberis plant, commonly referred to as Barberry, botanically known as Berberis thunbergii and hereinafter referred to by the name ‘AMERA’.

The new Berberis plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new unique Berberis plants with unique plant form and attractive leaves.

The new Berberis plant originated from an open-pollination in 2005 of Berberis thunbergii ‘Rose Glow’, not patented, as the female, or seed parent and an unknown selection of Berberis thunbergii as the male, or pollen, parent. The new Berberis plant was discovered and selected by the Inventor during the summer of 2011 as a single plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.

Asexual reproduction of the new Berberis plant by softwood cuttings in a controlled greenhouse environment in Grand Haven, Mich. since the summer of 2011 has shown that the unique features of this new Berberis plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Berberis have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AMERA’. These characteristics in combination distinguish ‘AMERA’ as a new and distinct Berberis plant:

    • 1. Relatively compact, upright, outwardly spreading and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Leaves that are initially yellow green in color with orange red-colored margins becoming darker yellow green in color with development.
    • 5. Good garden performance.

Plants of the new Berberis can be compared to plants of the female parent, ‘Rose Glow’. Plants of the new Berberis differ primarily from plants of ‘Rose Glow’ in leaf color as plants of ‘Rose Glow’ have pink and burgundy bi-colored leaves.

Plants of the new Berberis can be compared to plants of Berberis thunbergii ‘ARLENE’, disclosed in U.S. Plant patent application Ser. No. 16/350,428. Plants of the new Berberis are more compact and more mounding than and not as outwardly spreading as plants of ‘ARLENE’. In addition, plants of the new Berberis have solid-colored developed leaves whereas plants of ‘ARLENE’ have variegated leaves.

Plants of the new Berberis can also be compared to plants of the Berberis thunbergii, ‘Koren’, disclosed in U.S. Plant Pat. No. 24,818. In side-by-side comparisons, plants of the new Berberis differ primarily from plants of ‘Koren’ in the following characteristics:

    • 1. Plants of the new Berberis are more compact than plants of ‘Koren’.
    • 2. Plants of the new Berberis and ‘Koren’ differ in developing leaf color as plants of the new Berberis have leaves that are initially yellow green in color with orange red-colored margins whereas plants of ‘Koren’ have leaves that do not have an orange red-colored margins.
    • 3. Plants of the new Berberis and ‘Koren’ differ in developed leaf color as plants of the new Berberis have lighter yellow green-colored leaves than plants of ‘Koren’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Berberis plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 plant.

The photograph on the first sheet is a side perspective view of a typical plant of ‘AMERA’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘AMERA’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in a polythelene-covered greenhouse in Grand Haven, Mich. and under cultural practices which closely approximate commercial Berberis production. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. Plants were about two years old when the photographs and detailed description were taken. In the following detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
