Abstract

A new and distinct cultivar of Penstemon plant named ‘Florpenmag’, characterized by its deep purplish-red and white colored flowers, medium green-colored foliage, and vigorous, upright growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Penstemon hartwegii.

Variety denomination: ‘Florpenmag’.

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 cultivar name ‘Florpenmag’.

The new cultivar originated in a controlled breeding program in Quedlinburg, Germany during July 2011. The objective of the breeding program was the development of a Penstemon cultivar having large flowers and a long flowering season.

The new Penstemon cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is the proprietary Penstemon hartwegii breeding selection coded 2525-1, not patented, characterized by its medium burgundy-colored flowers, medium green-colored foliage, low growth vigor and upright growth habit. The male (pollen) parent of the new cultivar is unknown. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during September 2012 in a controlled environment in Quedlinburg, Germany.

Asexual reproduction of the new cultivar by terminal stem cuttings since September 2012 in Quedlinburg, Germany and Elburn, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Florpenmag’ as a new and distinct cultivar of Penstemon plant:

- 1. Deep purplish-red and white colored flowers;
- 2. Medium green-colored foliage; and
- 3. Vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and growth vigor.

Of the many commercially available Penstemon cultivars, the most similar in comparison to the new cultivar is Polaris Purple ‘Florpenpur’, not patented. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Florpenpur’ in at least the following characteristics:

- 1. Plants of the new cultivar have more red in the flower color than plants of ‘Florpenpur’; and
- 2. Plants of the new cultivar are more vigorous than plants of ‘Florpenpur’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Florpenmag’ The plants were approximately 20 weeks old and grown in 1.7 gallon containers. Plants were finished outdoors for 10 weeks in West Chicago, Ills. Plants were given two pinches prior to transplant.

FIG. 2 illustrates a close-up view of an inflorescence of ‘Florpenmag’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in July 2016 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown utilizing a soilless growth medium in 1.7 gallon containers for approximately 20 weeks. Plants were given two pinches prior to transplant. For approximately 8 weeks after transplant, greenhouse temperatures were maintained at approximately 60° F. (15.6° C.) during the day and approximately 55° F. (12.8° C.) during the night. For the final 10 weeks, plants were grown outside in West Chicago, Ill. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
