Abstract

A new and distinct cultivar of Physocarpus plant named ‘SMPOTW’, characterized by its compact, upright and uniform plant habit; vigorous growth habit; freely branching habit; dense and bushy habit; small dark green-colored leaves that become greyed purple in color under high light (full sun) conditions and red during the autumn; showy inflorescences with numerous pink-colored flower buds and white and pink-colored flowers; good garden performance; and resistance to Powdery Mildew.

Description

Botanical designation: Physocarpus opulifolius.
Cultivar denomination: ‘SMPOTW’.
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 ‘SMPOTW’.
The new Physocarpus plant is a product of a controlled breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to create new Physocarpus plants with unique flower forms.
The new Physocarpus plant originated from an open-pollination during the summer of 2006 in Grand Haven, Mich. of Physocarpus opulifolius ‘Seward’, disclosed in U.S. Plant Pat. No. 14,821, 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 2008 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.
Asexual reproduction of the new Physocarpus plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since July, 2008 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 ‘SMPOTW’. These characteristics in combination distinguish ‘SMPOTW’ as a new and distinct Physocarpus plant:
    • 1. Compact, upright and uniform plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit; dense and bushy habit.
    • 4. Small dark green-colored leaves that become greyed purple in color under high light (full sun) conditions and red during the autumn.
    • 5. Showy inflorescences with numerous pink-colored flower buds and white and pink-colored flowers.
    • 6. Good garden performance.
    • 7. Resistant to Powdery Mildew.
Plants of the new Physocarpus can be compared to plants of the female parent, ‘Seward’. Plants of the new Physocarpus differ from plants of ‘Seward’ in the following characteristics:
    • 1. Plants of the new Physocarpus are more compact than plants of ‘Seward’.
    • 2. Plants of the new Physocarpus have smaller leaves than plants of ‘Seward’.
    • 3. Plants of the new Physocarpus and ‘Seward’ differ in leaf color as plants of ‘Seward’ have dark purple-colored leaves.
    • 4. Flowers of plants of the new Physocarpus are darker pink in color than flowers of plants of ‘Seward’.
Plants of the new Physocarpus can be compared to plants of the Physocarpus ‘Little Devil’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Physocarpus differed from plants of ‘Little Devil’ in the following characteristics:
    • 1. Plants of the new Physocarpus were more compact than plants of ‘Little Devil’.
    • 2. Plants of the new Physocarpus and ‘Little Devil’ differed in leaf color.
    • 3. Plants of the new Physocarpus were more resistant to Powdery Mildew than plants of ‘Little Devil’.
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 ‘SMPOTW’ grown under full sun conditions in an outdoor nursery in late spring/early summer.
The photograph on the second sheet is a close-up view of a typical plant of ‘SMPOTW’ grown under full sun conditions in an outdoor nursery in the autumn.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring, summer and autumn under full sun conditions 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.
