STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Dümmen Group B.V. of De Lier, The Netherlands on Jan. 13, 2021, application number 2021/0125. Foreign priority is not claimed to this application.

The Inventor and Applicant/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 and/or Applicant/Assignee. Inventor and Applicant/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 cultivar of Penstemon plant, botanically known as Penstemon hartwegii and hereinafter referred to by the name ‘Dopenpepredim’.

The new Penstemon plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to create new freely-branching Penstemon plants with attractive flower color.

The new Penstemon plant originated from a self-pollination in July, 2014 in Aalsmeer, The Netherlands, of a proprietary selection of Penstemon hartwegii identified as code number PE13-000001-007, not patented. The new Penstemon plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled environment in Aalsmeer, The Netherlands in May, 2015.

Asexual reproduction of the new Penstemon plant by terminal vegetative cuttings in a controlled environment in Aalsmeer, The Netherlands since June, 2015 has shown that the unique features of this new Penstemon plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. Upright plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Relatively large red-colored flowers with white-colored centers.
  • 7. Good garden performance.

Plants of the new Penstemon differ primarily from plants of the parent selection in flower color as plants of the new Penstemon have red-colored flowers with white-colored throats whereas plants of the parent selection have solid red-colored flowers.

Plants of the new Penstemon can also be compared to plants of Penstemon hartwegii ‘PepTalk Red’, not patented. In side-by-side comparisons, plants of the new Penstemon and ‘PepTalk Red’ differ in the following characteristics:

• • 1. Plants of the new Penstemon are shorter than plants of ‘PepTalk Red’.
  • 2. Flowers of plants of the new Penstemon open more broadly with development than flowers of plants of ‘PepTalk Red’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Penstemon 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 Penstemon plant. The photograph is a top perspective view of typical flowering plant of ‘Dopenpepredim’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 17-cm containers initially in a glass-covered greenhouse and finished in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Penstemon production. During the production of the plants, day temperatures averaged 21° C. and night temperatures averaged 15° C. Plants were 27 weeks old when the photograph and detailed description were 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.
