Abstract

A new cultivar of Physostegia plant, ‘Pink Manners’, characterized by its flowers that are light rose pink in color, its clump-forming growth habit due to its very short rhizomes, and its mature height of 76 to 107 cm.

Description

Botanical classification: Physostegia virginiana.
Variety denomination: ‘Pink Manners’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Obedient Plant, botanically known as Physostegia virginiana ‘Pink Manners’ and will be referred to hereinafter by its cultivar name, ‘Pink Manners’. The new cultivar of Physostegia is a hardy herbaceous perennial grown for landscape use.
The new cultivar was developed through a breeding program conducted by the inventor in Hubbardston, Mass. The goal was to produce a cultivar of Physostegia that produced pink flowers and exhibited a clump-forming growth habit that lacked the spreading growth habit by long rhizomes that is typical of cultivars of pink flowering Physostegia.
‘Pink Manners’ arose from a cross made in August of 2005 between unnamed advanced generation plants from the inventor's breeding program as both the female and male parents. ‘Pink Manners’ was selected as a single unique plant in July of 2008.
Asexual reproduction of the new cultivar was first accomplished by division in October of 2008 by the inventor in Hubbardston, Mass. It has been determined that the characteristics are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Pink Manners’ as a unique cultivar of Physostegia.
    • 1. ‘Pink Manners’ exhibits flowers that are light rose pink in color.
    • 2. ‘Pink Manners’ exhibits a clump-forming growth habit.
    • 3. ‘Pink Manners’ exhibits very short rhizomes.
    • 4. ‘Pink Manners’ attains a height of 76 to 107 cm (30 to 42 inches).
‘Pink Manners’ can be compared to its parent plants. The female parent is similar to ‘Pink Manners’ in having flowers that are pink in color, but differs from ‘Pink Manners’ in having long rhizomes and therefore lacking a clump-forming plant habit. The male parent is similar to ‘Pink Manners’ in having very short rhizomes and a clump-forming plant habit, but differs from ‘Pink Manners’ in having flowers that are white in color. ‘Pink Manners’ can also be compared to the cultivars ‘Miss Manners’ (U.S. Plant Pat. No. 12,637) and ‘Rosea’ (not patented). ‘Miss Manners’ is similar to ‘Pink Manners’ in having a clump-forming growth habit, but differs from ‘Pink Manners’ in having flowers that are white in color and in being shorter in height. ‘Rosea’ is similar to ‘Pink Manners’ in plant height and in having flowers that are light rose pink in color, but differs from ‘Pink Manners’ in having long rhizomes with a spreading growth habit.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Physostegia.
The plant depicted in FIG. 1 is about one year in age as grown outdoors in a one-gallon container in Kensington, Conn. and provides a close-up view of the inflorescences of ‘Pink Manners’.
The plant in the photograph in FIG. 2 was about one year in age from a division as grown in a garden in Hubbardston, Mass. and illustrates the rhizomes on current season's stems still attached to the old (dead) stems.
The plant depicted in FIG. 3 is about 18 months in age as grown in New Hope, Minn. and illustrates the clump forming growth habit of ‘Pink Manners’. The 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 Physotegia.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of two year-old plants of the new cultivar as grown outdoors in a garden in New Hope, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
