Abstract

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

Description

Botanical designation: Phlox drummondii.
Cultivar denomination: ‘SUNPHLOSIRO’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox drummondii and hereinafter referred to by the name ‘Sunphlosiro’.
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 was to create new compact, mounding and freely branching Phlox plants with attractive flower coloration.
The new Phlox plant originated from a cross-pollination made by the Inventor in July, 2006 in Higashiomi, Shiga, Japan, of a proprietary selection of Phlox drummondii identified as code number 6Ph-16a, not patented, as the female, or seed, parent with a proprietary selection of Phlox drummondii identified as code number 0Ph-32a, not patented, as the male, or pollen, parent. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in May, 2007.
Asexual reproduction of the new Phlox plant by cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since June, 2007 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 and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Sunphlosiro’. These characteristics in combination distinguish ‘Sunphlosiro’ as a new and distinct Phlox plant:
    • 1. Compact and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching and flowering habit.
    • 4. Long flowering period.
    • 5. White-colored flowers.
    • 6. Good garden performance.
Plants of the new Phlox differ from plants of the female parent selection primarily in plant habit plants of the female parent selection are more compact than plants of the new Phlox. In addition, plants of the new Phlox are more heat tolerant than plants of the female parent selection.
Plants of the new Phlox differ from plants of the male parent selection primarily in flower size as plants of the male parent selection have smaller flowers. In addition, plants of the new Phlox are smaller than plants of the male parent selection.
Plants of the new Phlox can be compared to plants of Phlox drummondii ‘Sunphloho’, disclosed in U.S. Plant Pat. No. 16,724. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Phlox and ‘Sunphloho’ differed in the following characteristics:
    • 1. Plants of the new Phlox were smaller and had shorter internodes than plants of ‘Sunphloho’.
    • 2. Plants of the new Phlox were not as upright as plants of ‘Sunphloho’.
Plants of the new Phlox can be compared to plants of Phlox drummondii ‘Sunphloconsa’, disclosed in U.S. Plant Pat. No. 20,897. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Phlox and ‘Sunphloconsa’ differed in the following characteristics:
    • 1. Plants of the new Phlox were shorter than plants of ‘Sunphloconsa’.
    • 2. Plants of the new Phlox were more freely flowering than plants of ‘Sunphloconsa’.
    • 3. Plants of the new Phlox and ‘Sunphloconsa’ differed in flower color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Phlox plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 plant.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunphlosiro’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunphlosiro’.
 DETAILED BOTANICAL DESCRIPTION
