Abstract

A new and distinct cultivar of Eupatorium plant named ‘Doeuplipy’, characterized by its relatively compact and broadly upright plant habit; freely branching habit; freely flowering habit; large purple-colored inflorescences; and good container and garden performance.

Description

Botanical designation: Eupatorium maculatum.

Cultivar denomination: ‘DOEUPLIPY’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Inventor and Applicant on May 4, 2021, application number 2021/1218. Foreign priority is not claimed to this application.

The Inventor and Applicant 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 and Applicant. Inventor and Applicant 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 cultivar of Eupatorium plant, botanically known as Eupatorium maculatum, commonly referred to as Joe-Pye Weed and hereinafter referred to by the name ‘Doeuplipy’.

The new Eupatorium plant is a product of a planned breeding program conducted by the Inventor in Rijpwetering, The Netherlands. The objective of the breeding program is to create new compact Eupatorium plants that are suitable as container and garden plants.

The new Eupatorium plant originated from an open-pollination in August, 2015 in Rijpwetering, The Netherlands of Eupatorium maculatum ‘Phantom’, disclosed in U.S. Plant Pat. No. 18,354, as the female, or seed parent with an unknown selection of Eupatorium maculatum, as the male, or pollen, parent. The new Eupatorium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Rijpwetering, The Netherlands in September, 2016.

Asexual reproduction of the new Eupatorium plant by terminal vegetative cuttings in a controlled greenhouse environment in Rijpwetering, The Netherlands since September, 2016 has shown that the unique features of this new Eupatorium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Eupatorium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘Doeuplipy’. These characteristics in combination distinguish ‘Doeuplipy’ as a new and distinct Eupatorium plant:

- 1. Relatively compact and broadly upright plant habit.
- 2. Freely branching habit.
- 3. Freely flowering habit.
- 4. Large purple-colored inflorescences.
- 5. Good container and garden performance.

Plants of the new Eupatorium differ primarily from plants of the female parent, ‘Phantom’, in plant habit as plants of the new Eupatorium are more compact than and not as tall as plants of ‘Phantom’.

Plants of the new Eupatorium can be compared to plants of Eupatorium maculatum ‘Snowball’, disclosed in U.S. Plant Pat. No. 22,869. In side-by-side comparisons, plants of the new Eupatorium differ primarily from plants of ‘Snowball’ in plant habit as plants of the new Eupatorium are more compact than and not as tall as plants of ‘Snowball’. In addition, plants of the new Eupatorium have purple-colored inflorescences whereas plants of ‘Snowball’ have creamy white-colored inflorescences.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Eupatorium 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 Eupatorium plant. The photograph is a side perspective view of a typical flowering plant of ‘Doeuplipy’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the summer in 17-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Eupatorium production. During the production of the plants, average daily temperatures were 22° C. and average night temperatures were 17° C. Plants were three months old when the photograph was taken and 16 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used.
