plant named ‘Sunphloconsa’

Abstract

A new and distinct cultivar of Phlox plant named ‘Sunphloconsa’, characterized by its compact and mounding plant habit; freely branching and flowering habit; long flowering period; salmon pink-colored flowers; and good garden performance.

Description

Botanical designation: Phlox drummondii.

Cultivar denomination: ‘Sunphloconsa’.

BACKGROUND OF THE INVENTION

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

The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact and mounding Phlox cultivars with freely branching habit, attractive flower coloration and tolerance to high temperatures.

The new Phlox plant originated from a cross-pollination made by the Inventor in Higashiomi, Shiga, Japan in June, 2004, of a proprietary selection of Phlox drummondii identified as code number 3Ph-24a, not patented, as the female, or seed parent with a proprietary selection of Phlox drummondii identified as code number 4Ph-19, not patented, as the male, or pollen, parent. The new Phlox was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in 2005.

Asexual reproduction of the new Phlox plant by cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since August 2005, has shown that the unique features of this new Phlox plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phlox have 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 ‘Sunphloconsa’. These characteristics in combination distinguish ‘Sunphloconsa’ as a new and distinct cultivar of Phlox:

• • 1. Compact and mounding plant habit.
  • 2. Freely branching and flowering habit.
  • 3. Long flowering period.
  • 4. Salmon pink-colored flowers.
  • 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 have larger flowers than plants of the female parent selection.
  • 2. Plants of the new Phlox and the female parent selection differ in flower color as plants of the female parent selection have light pink-colored flowers.

Plants of the new Phlox differ primarily from plants of the male parent selection in plant size as plants of the new Phlox are larger than plants of the male parent selection.

Plants of the new Phlox can also be compared to plants of Phlox drummondii ‘Sunphlopin’, disclosed in U.S. Plant Pat. No. 16,361. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Phlox and ‘Sunphlopin’ differed in the following characteristics:

• • 1. Plants of the new Phlox were not as broad as plants of ‘Sunphlopin’.
  • 2. Plants of the new Phlox had shorter internodes than plants of ‘Sunphlopin’.
  • 3. Plants of the new Phlox had larger leaves and flowers than plants of ‘Sunphlopin’.
  • 4. Plants of the new Phlox and ‘Sunphlopin’ differed in flower color as plants of ‘Sunphlopin’ have red purple-colored flowers.

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phlox.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunphloconsa’ grown in a container.

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