Abstract

A new and distinct cultivar of Penstemon plant named ‘Dopenspriscarl’, characterized by its upright and tall plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; red-colored flowers; and good garden performance.

Description

Botanical designation: Penstemon barbatus x heterophyllus.

Cultivar denomination: ‘DOPENSPRISCARL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Penstemon plant, botanically known as Penstemon barbatus x heterophyllus and hereinafter referred to by the name ‘Dopenspriscarl’.

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 an open-pollination in July, 2013 in Aalsmeer, The Netherlands, of a proprietary selection of Penstemon barbatus x heterophyllus identified as code number PE-0005, not patented, as the female, or seed, parent with an unknown selection of Penstemon barbatus x heterophyllus as the male, or pollen, parent. The new Penstemon 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 environment in Aalsmeer, The Netherlands in May, 2014.

Asexual reproduction of the new Penstemon plant by terminal vegetative cuttings in a controlled environment in Aalsmeer, The Netherlands since June, 2014 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 ‘Dopenspriscarl’. These characteristics in combination distinguish ‘Dopenspriscarl’ as a new and distinct Penstemon plant:

    • 1. Upright and tall plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Long flowering period.
    • 6. Red-colored flowers.
    • 7. Good garden performance.

Plants of the new Penstemon differ primarily from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Penstemon are more freely branching than plants of the female parent selection.
    • 2. Plants of the new Penstemon and the female parent selection differ in flower color as plants of the new Penstemon have red-colored flowers whereas plants of the female parent selection have dark red-colored flowers.

Plants of the new Penstemon can be compared to plants of Penstemon barbatus x heterophyllus ‘Dopensprisderos’, disclosed in U.S. Plant patent application 16/501,822 filed concurrently. Plants of the new Penstemon and ‘Dopensprisderos’ differ primarily in flower color as plants of the new Penstemon have red-colored flowers whereas plants of ‘Dopensprisderos’ have bright red purple-colored flowers. In addition, plants of the new Penstemon are taller than plants of ‘Dopensprisderos’.

Plants of the new Penstemon can also be compared to plants of Penstemon schmidel ‘Marble Riding Hood’, disclosed in U.S. Plant Patent number 23,098. In side-by-side comparisons, plants of the new Penstemon and ‘Marble Riding Hood’ differ in the following characteristics:

    • 1. Plants of the new Penstemon are taller than plants of ‘Marble Riding Hood’.
    • 2. Plants of the new Penstemon are more freely branching than plants of ‘Marble Riding Hood’.
    • 3. Plants of the new Penstemon have smaller leaves than plants of ‘Marble Riding Hood’.
    • 4. Plants of the new Penstemon have red-colored flowers whereas plants of ‘Marble Riding Hood’ have light red purple and white-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs 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 on the first sheet is a side perspective view of a typical flowering plant of ‘Dopenspriscarl’ grown in a container.

The photograph on the second sheet is a close-up view of typical flowers of ‘Dopenspriscarl’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 17-cm containers in a glass-covered greenhouse in Aalsmeer, The Netherlands and under cultural practices typical of commercial Penstemon production. During the production of the plants, day temperatures averaged 22° C. and night temperatures averaged 17° C. Plants were pinched one time and were three months old when the photographs were taken and 22 weeks old when the detailed description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
