Abstract

A new and distinct cultivar of Aronia plant named ‘SMNAMPEM’, characterized by its relatively compact, upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit; freely branching habit; medium green-colored leaves that become bright reddish orange during the autumn; upright inflorescences with numerous white-colored flowers; relatively large almost black-colored fruits; and good garden performance.

Description

Botanical designation: Aronia melanocarpa.

Cultivar denomination: ‘SMNAMPEM’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Aronia plant, botanically known as Aronia melanocarpa, commonly referred to as Black Chokeberry and hereinafter referred to by the name ‘SMNAMPEM’.

The new Aronia 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 compact and freely flowering Aronia plants with attractive autumn leaf color and large decorative fruits.

The new Aronia plant originated from an open-pollination in 2014 in Grand Haven, Mich. of Aronia melanocarpa ‘Professor Ed’, not patented, as the female, or seed, parent with an unknown selection of Aronia malanocarpa as the male, or pollen, parent. The new Aronia plant was discovered and selected by the Inventor in 2017 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 Aronia plant by softwood stem cuttings in a controlled environment in Grand Haven, Mich. since 2017 has shown that the unique features of this new Aronia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Aronia 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 ‘SMNAMPEM’. These characteristics in combination distinguish ‘SMNAMPEM’ as a new and distinct Aronia plant:

- 1. Relatively compact, upright, outwardly spreading and uniformly rounded plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Medium green-colored leaves that become bright reddish orange during the autumn.
- 5. Upright inflorescences with numerous white-colored flowers.
- 6. Relatively large almost black-colored fruits.
- 7. Good garden performance.

Plants of the new Aronia can be compared to plants of the female parent, ‘Professor Ed’. Plants of the new Aronia differ from plants of ‘Professor Ed’ in the following characteristics:

- 1. Plants of the new Aronia are more freely flowering than plants of ‘Professor Ed’.
- 2. Plants of the new Aronia produce more fruits per plant than plants of ‘Professor Ed’.
- 3. Plants of the new Aronia produce larger fruits than plants of ‘Professor Ed’.

Plants of the new Aronia can be compared to plants of the Aronia melanocarpa ‘UCONNAM165’, disclosed in U.S. Plant Pat. No. 28,789. In side-by-side comparisons, plants of the new Aronia differ from plants of ‘UCONNAM165’ in the following characteristics:

- 1. Plants of the new Aronia are slightly taller than plants of ‘UCONNAM165’.
- 2. Plants of the new Aronia are more freely branching than plants of ‘UCONNAM165’.
- 3. Plants of the new Aronia are more freely flowering than plants of ‘UCONNAM165’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Aronia 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 Aronia.

The photograph on the first sheet (FIG. 1) is a side perspective view of typical flowering plants of ‘SMNAMPEM’ grown in containers.

The photograph on the second sheet (FIG. 2) is a close-up view of typical leaves of ‘SMNAMPEM’ during the autumn.

The photograph on the third sheet (FIG. 3) is a close-up view of typical fruits of ‘SMNAMPEM’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown throughout the year in three-gallon containers in a polyethylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial Aronia production. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from ranged from 5° C. to 10° C. Plants were two years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
