Phlox plant named ‘Wesposky’

Abstract

A new and distinct cultivar of Phlox plant named ‘Wesposky’, characterized by its compact, upright and mounting plant habit; freely branching growth habit; freely and continuous flowering habit; long flowering period; white colored flowers with a light violet-colored central star pattern; and good garden performance.

Description

Botanical Designation: Phlox hybrida.

Cultivar Denomination: ‘Wesposky’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox, botanically known as Phlox hybrida and hereinafter referred to by the name ‘Wesposky’.

The new Phlox is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program was to create new compact and freely branching Phlox cultivars with numerous attractive flowers.

The new Phlox originated from a cross-pollination made by the Inventor in 2004, in Südlohn, Germany, of a proprietary selection of Phlox hybrida identified as code number 04P005, not patented, as the female, or seed, parent with a proprietary selection of Phlox hybrida identified as code number 04P010, not patented, as the male, or pollen, parent. The new Phlox was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Südlohn, Germany in 2005.

Asexual reproduction of the new Phlox by vegetative cuttings in a controlled environment in Südlohn, Germany since 2005 has shown that the unique features of this new Phlox are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Wesposky has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

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

• • 1. Compact, upright and mounding plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely and continuous flowering habit; long flowering period.
  • 4. White-colored flowers with a light violet-colored central star pattern.
  • 5. Good garden performance.

Plants of the new Phlox differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Phlox are more freely branching than plants of the female parent selection.
  • 2. Plants of the new Phlox have larger and lighter green-colored leaves than plants of the female parent selection.

Plants of the new Phlox differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Phlox are more compact than plants of the male parent selection.
  • 2. Plants of the new Phlox and the male parent selection differ in flower color as plants of the male parent selection have white-colored flowers.

Plants of the new Phlox can be compared to plants of the Phlox cultivar USPHL304, disclosed in U.S. Plant Pat. No. 17,899. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Phlox differed from plants of the cultivar USPHL304 in the following characteristics:

• • 1. Plants of the new Phlox were more compact than plants of the cultivar USPHL304.
  • 2. Plants of the new Phlox had stronger lateral branches than plants of the cultivar USPHL304.
  • 3. Plants of the new Phlox had smaller flowers than plants of the cultivar USPHL304.
  • 4. Plants of the new Phlox and the cultivar USPHL304 differed in flower color as plants of the USPHL304 had lavender-colored flowers with a white and purple-colored star pattern at the center.

Plants of the new Phlox can also be compared to plants of the Phlox cultivar Astoria White, not patented. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Phlox differed from plants of the cultivar Astoria White in the following characteristics:

• • 1. Plants of the new Phlox had stronger lateral branches than plants of the cultivar Astoria White.
  • 2. Plants of the new Phlox had larger leaves than plants of the cultivar Astoria White.
  • 3. Plants of the new Phlox and the cultivar Astoria White differed in flower color as plants of the Astoria White had white-colored flowers
