Abstract

A new and distinct cultivar of Physocarpus plant named ‘Bert Dart's G’, characterized by its compact and mounded plant habit; freely branching habit; dense and bushy habit; yellow to yellow green-colored leaves; showy inflorescences with numerous white-colored flowers; good garden performance; and resistance to Powdery Mildew.

Description

Botanical designation: Physocarpus opulifolius.
Cultivar denomination: ‘BERT DART'S G’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Physocarpus plant, botanically known as Physocarpus opulifolius and hereinafter referred to by the name ‘Bert Dart's G’.
The new Physocarpus plant is a product of a controlled breeding program conducted by the Inventor in Hazerswoude, The Netherlands. The objective of the breeding program is to create new compact Physocarpus plants with yellow green-colored leaves and resistance to Powdery Mildew.
The new Physocarpus plant originated from an open-pollination in June, 2008 in Hazerswoude, The Netherlands of Physocarpus opulifolius ‘Dart's Gold’, not patented, as the female, or seed, parent with an unknown selection of Physocarpus opulifolius as the male, or pollen, parent. The new Physocarpus plant was discovered and selected by the Inventor in May, 2010 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Hazerswoude, The Netherlands.
Asexual reproduction of the new Physocarpus plant by softwood cuttings in a controlled environment in Hazerswoude, The Netherlands since May, 2010 has shown that the unique features of this new Physocarpus plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Physocarpus 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 ‘Bert Dart's G’. These characteristics in combination distinguish ‘Bert Dart's G’ as a new and distinct Physocarpus plant:
    • 1. Compact and mounded plant habit.
    • 2. Freely branching habit; dense and bushy habit.
    • 3. Yellow to yellow green-colored leaves.
    • 4. Showy inflorescences with numerous white-colored flowers.
    • 5. Good garden performance.
    • 6. Resistant to Powdery Mildew.
Plants of the new Physocarpus can be compared to plants of the female parent, ‘Dart's Gold’. Plants of the new Physocarpus differ from plants of ‘Dart's Gold’ in the following characteristics:
    • 1. Plants of the new Physocarpus are more compact than plants of ‘Dart's Gold’.
    • 2. Plants of the new Physocarpus are more resistant to Powdery Mildew than plants of ‘Dart's Gold’.
Plants of the new Physocarpus can be compared to plants of the Physocarpus ‘Nugget’, not patented. In side-by-side comparisons conducted in Hazerswoude, The Netherlands, plants of the new Physocarpus differed from plants of ‘Nugget’ in the following characteristics:
    • 1. Plants of the new Physocarpus were more compact than plants of ‘Nugget’.
    • 2. Plants of the new Physocarpus were more mounded than and not as arching as plants of ‘Nugget’.
    • 3. Plants of the new Physocarpus and ‘Nugget’ differed in leaf color.
    • 4. Plants of the new Physocarpus were more resistant to Powdery Mildew than plants of ‘Nugget’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Physocarpus, 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 Physocarpus.
The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Bert Dart's G’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Bert Dart's G’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in ground beds in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial production. Plants were three years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
