Description
Botanical designation: Phlox hybrida.
Cultivar denomination: ‘USPLX60306’.
The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox hybrida and hereinafter referred to by the name ‘USPLX60306’.
The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new uniformly mounding Phlox plants with unique flower color and resistance to Powdery Mildew.
The new Phlox plant originated from a cross-pollination made by the Inventor on Sep. 9, 2006 in Higashiomi, Shiga, Japan of Phlox hybrida ‘Candy Box Blue’, not patented, as the female, or seed, parent with an unnamed seedling selection of Phlox hybrida, 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 environment in Bonsall, Calif. on Jul. 17, 2007.
Asexual reproduction of the new Phlox plant by cuttings in a controlled environment in Bonsall, Calif. since Jul. 23, 2007, has shown that the unique features of this new Phlox plant are stable and reproduced true to type in successive generations.
Plants of the new Phlox plant 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 ‘USPLX60306’. These characteristics in combination distinguish ‘USPLX60306’ as a new and distinct cultivar of Phlox:
-
- 1. Upright, outwardly spreading and mounding plant form.
- 2. Fast rooting.
- 3. Vigorous growth habit.
- 4. Freely branching habit and short internodes; dense and busy plant habit.
- 5. Freely and continuous flowering habit.
- 6. Dark violet to violet blue-colored flowers.
- 7. Relatively tolerant to high temperatures.
- 8. Relatively resistant to Powdery Mildew.
Plants of the new Phlox can be compared to plants of the parents. Plants of the new Phlox differ from plants of the female parent, ‘Candy Box Blue’, primarily in flower color as plants of the new Phlox have darker-colored flowers than plants of ‘Candy Box Blue’.
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 vigorous than plants of the male parent selection.
- 2. Plants of the new Phlox are more freely branching than plants of the male parent selection.
- 3. Plants of the new Phlox are denser than and not as open as plants of the male parent selection.
Plants of the new Phlox can be compared to plants of the Phlox ‘Sunphloburu’, disclosed in U.S. Plant Pat. No. 18,451. In side-by-side comparisons, plants of the new Phlox and ‘Sunphloburu’ differed in the following characteristics:
-
- 1. The plant habit of plants of the new Phlox was more uniform than the plant habit of plants of ‘Sunphloburu’.
- 2. Plants of the new Phlox had darker-colored flowers than plants of ‘Sunphloburu’.
- 3. Under high light conditions, the flower color of plants of the new Phlox faded less than the flower color of plants of ‘Sunphloburu’.
- 4. Plants of the new Phlox were more resistant to Powdery Mildew than plants of ‘Sunphloburu’.
Plants of the new Phlox can also be compared to plants of the Phlox ‘Blue Star’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Blue Star’ differed in the following characteristics:
-
- 1. Plants of the new Phlox had darker-colored flowers than plants of ‘Blue Star’.
- 2. Under high temperature conditions, the flower color of plants of the new Phlox faded less than the flower color of plants of ‘Blue Star’.
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 bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘USPLX60306’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical flowers and leaves of ‘USPLX60306’.
The aforementioned photographs and following observations, measurements and values describe plants grown in Bonsall, Calif., under commercial practice in 12.5-cm containers during the autumn in an outdoor nursery with day temperatures ranging from 18° C. to 38° C., night temperatures ranging from 9° C. to 18° C. and light levels ranging from 7,000 to 10,000 foot-candles. Plants were pinched one time and were six weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
