Abstract

A new and distinct cultivar of Phlox plant named ‘Spinners’, characterized by its upright and strong plant habit; freely basally branching habit; dense and bushy growth habit; thick and leathery foliage; attractive red-purple-colored flowers with white stripes; freely and continuous flowering habit; long flowering period; resistance to Powdery Mildew; and excellent garden performance.

Description

Botanical designation: Phlox paniculata.

Cultivar denomination: ‘Spinners’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox paniculata, and hereinafter referred to by the cultivar name Spinners.

The new Phlox is a product of a planned breeding program conducted by the Inventor in Zwaanshoek, The Netherlands. The objective of the breeding program was to create new Phlox cultivars with attractive flower coloration, healthy foliage and resistance to Powdery Mildew.

The new Phlox originated from a cross-pollination made by the Inventor in 1999 in Callantsoog, The Netherlands of a proprietary selection of Phlox paniculata identified as code number 98421, not patented, as the female, or seed, parent with a proprietary selection of Phlox paniculata identified as code number 96562, not patented, as the male, or pollen, parent. The new Phlox was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Callantsoog, The Netherlands in 2001.

Asexual reproduction of the new cultivar by terminal cuttings at Callantsoog, The Netherlands since 2001, has shown that the unique features of this new Phlox are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Spinners have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Spinners’. These characteristics in combination distinguish ‘Spinners’ as a new and distinct cultivar of Phlox:

• • 1. Upright and strong plant habit.
  • 2. Freely basally branching habit; dense and bushy growth habit.
  • 3. Thick and leathery foliage.
  • 4. Attractive red purple-colored flowers with white stripes.
  • 5. Freely and continuous flowering habit.
  • 6. Long flowering period.
  • 7. Resistant to Powdery Mildew.
  • 8. Excellent garden performance.

Plants of the new Phlox differ primarily from plants of the parent selections in flower color. In addition, plants of the new Phlox have healthier foliage than plants of the male parent selection.

Plants of the new Phlox can be compared to the Phlox paniculata cultivar Bright Eyes, not patented. In side-by-side comparisons conducted in Zwaanshoek, The Netherlands, plants of the new Phlox differed from plants of the cultivar Bright Eyes primarily in flower color as plants of the cultivar Bright Eyes have pink-colored flowers with red purple-colored centers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ2 slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Phlox.

The photograph at the top of the sheet is a close-up view of typical flowers of ‘Spinners’.

The photograph at the bottom of the sheet comprises a side perspective view of a typical plants of ‘Spinners’.
