Abstract

A new and distinct cultivar of Barberry plant named ‘Mimi’, characterized by its compact and low mounding plant habit; vigorous growth habit; freely branching habit; leaves that are dark purple in color; good garden performance; and resistance to Black Stem Rust.

Description

Botanical designation: Berberis thunbergii.
Cultivar denomination: ‘MIMI’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Barberry plant, botanically known as Berberis thunbergii and hereinafter referred to by the name ‘Mimi’.
The new Barberry 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 Barberry plants with attractive foliage, improved stress tolerance and resistance to Black Stem Rust (Puccinia graminis).
The new Barberry plant originated from an open-pollination in June, 2003 of Barberry thunbergii ‘Concorde’, not patented, as the female, or seed parent and an unknown selection of Barberry thunbergii as the male, or pollen, parent. The new Barberry plant was discovered and selected by the Inventor during the summer of 2006 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 Barberry plant by softwood cuttings in a controlled greenhouse environment in Grand Haven, Mich. since the summer of 2007 has shown that the unique features of this new Barberry plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Barberry have not been observed under all possible 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 ‘Mimi’. These characteristics in combination distinguish ‘Mimi’ as a new and distinct Barberry plant:
    • 1. Compact and low mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Leaves that are dark purple in color.
    • 5. Good garden performance.
    • 6. Resistance to Black Stem Rust.
Plants of the new Barberry can be compared to plants of the female parent, ‘Concorde’. Plants of the new Barberry differ from plants of ‘Concorde’ in the following characteristics:
    • 1. Plants of the new Barberry are more vigorous than plants of ‘Concorde’.
    • 2. Plants of the new Barberry and ‘Concorde’ differ in leaf color as plants of ‘Concorde’ have dark purple red-colored leaves.
Plants of the new Barberry can be compared to plants of the Berberis thunbergii ‘Crimson Pygmy’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Barberry differed from plants of ‘Crimson Pygmy’ in the following characteristics:
    • 1. Plants of the new Barberry grew more uniformly than plants of ‘Crimson Pygmy’.
    • 2. Plants of the new Barberry were more compact than plants of ‘Crimson Pygmy’.
    • 3. Plants of the new Barberry were more freely branching than plants of ‘Crimson Pygmy’.
Plants of the new Barberry can be also compared to plants of the Berberis thunbergii ‘Bagatelle’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Barberry differed from plants of ‘Bagatelle’ in the following characteristics:
    • 1. Plants of the new Barberry were more vigorous than plants of ‘Bagatelle’.
    • 2. Plants of the new Barberry and ‘Bagatelle’ differed in leaf color as plants of ‘Bagatelle’ had brownish burgundy-colored leaves.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Barberry plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Barberry plant.
The photograph is a side perspective view of a typical plant of ‘Mimi’ grown in an outdoor nursery.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations, measurements and values describe plants grown during the spring and summer in an outdoor nursery in Grand Haven, Mich. and under cultural practices which closely approximate commercial production. Plants used for the photograph and description were two years old. In the following detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
