plant named ‘Flock of Flamingos’

Abstract

A new and distinct Penstemon plant characterized by its large, rose-pink flowers with a clean white throat, dense flower clusters, long bloom time, a strong, upright, and well branched habit with approximately 12 crowns from the base, clean-looking, deep green, and attractive foliage, and excellent vigor.

Description

Botanical classification: Penstemon spp.

Varietal denomination: ‘Flock of Flamingos’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct Penstemon plant, of the family Scrophulariaceae, having the varietal name ‘Flock of Flamingos’. The new variety originated as an open-pollinated cross in July of 2017 in the breeding fields of the applicant in Canby, Oregon using Penstemon plant named ‘Strawberry Taffy’ (U.S. Plant Pat. No. PP22,569) as the seed parent. ‘Strawberry Taffy’ is a complex hybrid, utilizing the hartwegii species. ‘Flock of Flamingos’ was selected for its medium-large, upright growth habit, large flowers in dense clusters, long flowering time, high vigor, and attractive foliage.

When compared to its seed parent, Penstemon plant named ‘Strawberry Taffy’, the new variety has a longer bloom time, larger and longer inflorescences, more stems from the crown, and a more upright growth habit. When compared to Penstemon plant named ‘Cha Cha Pink’ (U.S. Plant Pat. No. PP26,673), the new variety has a much larger habit, larger flowers with a brighter pink color and an unstriped throat, and numerous basal branches.

The new variety has only been reproduced by asexual propagation (cuttings and micropropagation using standard micropropagation practices). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and micropropagation using terminal and lateral shoots was first performed in late June of 2019 in Canby, Oregon shows that the characteristics and distinctions described herein come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

When compared to other Penstemon plants known to the breeder, the new variety is characterized by the following:

• • 1. Large rose-pink flowers with clean white throats;
  • 2. Large, dense flower clusters;
  • 3. Long bloom time;
  • 4. Large, upright, and well-branched habit, with approximately 12 crowns from the base;
  • 5. Attractive foliage; and
  • 6. High vigor.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the colors being as nearly true as possible with color illustrations of this type:
