USPP21329P2 - Phlox plant named ‘Triple Play’ - Google Patents

Abstract

A new cultivar of Phlox, ‘Triple Play’, characterized by its flowers that are pink in color with a darker pink eye zone, its variegated foliage with green centers and a creamy white margins that are flushed with pink when grown under cool temperatures (spring and autumn), its short stature, and its cold hardiness at least to U.S.D.A. Zone 5.

Description

Botanical Classification: Phlox glaberrima ssp. triflora.

Cultivar designation: ‘Triple Play’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox glaberrima ssp. triflora ‘Triple Play’ and will be referred to hereafter by its cultivar name, ‘Triple Play’. The new cultivar represents a new herbaceous perennial grown for landscape use.

The Inventors discovered the new cultivar, ‘Triple Play’, in their garden in Carlisle, Mass. in September of 2002. ‘Triple Play’ originated as a single variegated basal stem mutation on an unnamed plant of Phlox glaberrima ssp. triflora.

Asexual reproduction of the new cultivar was first accomplished by stem layering in Carlisle, Mass. in September of 2002 by the Inventors. Propagation by stem layering and stem cuttings has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar for a period of six years. These attributes in combination distinguish ‘Triple Play’ from other varieties of Phlox known to the Inventors

• • 1. ‘Triple Play’ exhibits flowers that are pink in color with a darker pink eye zone.
  • 2. ‘Triple Play’ exhibits variegated foliage with green centers and creamy white margins that are flushed with pink when grown under cool temperatures (spring and autumn).
  • 3. ‘Triple Play’ matures to a shorter height than is typical of the species.
  • 4. ‘Triple Play’ is hardy at least to U.S.D.A. Zone 5.

‘Triple Play’ differs from its parent variety in having variegated foliage. In addition, the ‘Triple Play’ is shorter in height, maturing to about 38 cm in height with the parent plant maturing to 60 cm to 75 cm in height. The new cultivar is most similar in plant habit and flower form to the cultivar Phlox glaberrima ‘Morris Berd’ (not patented). ‘Triple Play’ is comparable in having a similar growth habit and flower color. ‘Triple Play’ differs in having variegated foliage and a more compact growth habit. The new cultivar may also be compared to Phlox stolonifera ‘Variegata’ (not patented). ‘Variegata’ is similar in having variegated foliage, however, ‘Variegata’ differs from ‘Triple Play’ in being a cultivar of a different species, in having a vigorous stoloniferous habit, blooming about four weeks earlier, exhibiting leaves that are more rounded, and in being shorter in height.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Phlox. The photographs were taken in June 2008 of two year-old plants of ‘Triple Play’ as grown outdoors in a garden in Carlisle, Mass. The photograph in FIG. 1 is a view of a plant of ‘Triple Play’ in bloom. The photograph in FIG. 2 is a close-up view of the flowers of ‘Triple Play’. The Photograph in FIG. 3 provides a close-up view of the foliage in spring. 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 Phlox.
