Abstract

A new and distinct Phlox plant named ‘Aurora’, characterized by its upright and mounding plant form; vigorous growth habit; freely basal branching habit; early and freely flowering habit; large rounded inflorescences with white and pink-colored flowers; and resistance to Powdery Mildew.

Description

Botanical designation: Phlox×hybrida.
Cultivar denomination: ‘AURORA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Phlox plant, botanically known as Phlox×hybrida and hereinafter referred to by the name ‘Aurora’.
The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Upper Tyrone Township, Pa. The objective of the breeding program is to create new vigorous Phlox plants with early flowering habit, attractive leaf and flower coloration and resistance to Powdery Mildew.
The new Phlox plant originated from an open-pollination in July, 2008 of an unnamed seedling selection of Phlox maculata, not patented, as the female, or seed, parent with an unknown selection of Phlox×hybrida 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 open-pollination in a controlled environment in Upper Tyrone Township, Pa. in June, 2009.
Asexual reproduction of the new Phlox plant by vegetative stem cuttings in a controlled greenhouse environment in Upper Tyrone Township, Pa. since September, 2009 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 plant have not been observed under all possible combinations of 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 ‘Aurora’. These characteristics in combination distinguish ‘Aurora’ as a new and distinct Phlox plant:
    • 1. Upright and mounding plant form.
    • 2. Vigorous growth habit.
    • 3. Freely basal branching habit.
    • 4. Early and freely flowering habit.
    • 5. Large rounded inflorescences with white and pink-colored flowers.
    • 6. Resistance to Powdery Mildew.
Plants of the new Phlox differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Phlox are shorter than plants of the female parent selection.
    • 2. Inflorescences of plants of the new Phlox are rounded or dome-shaped whereas inflorescences of plants of the female parent selection are cylindrical in shape.
    • 3. Plants of the new Phlox and the female parent selection differ in flower color as plants of the female parent selection have pink-colored flowers.
Plants of the new Phlox can be compared to plants of Phlox carolina ‘Minnie Pearl’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Minnie Pearl’ differed in the following characteristics:
    • 1. Plants of the new Phlox were not as outwardly spreading and loose in plant habit as plants of ‘Minnie Pearl’.
    • 2. Plants of the new Phlox had shorter internodes than plants of ‘Minnie Pearl’.
    • 3. Leaves of plants of the new Phlox were glossier than leaves of plants of ‘Minnie Pearl’.
    • 4. Inflorescences of plants of the new Phlox faced upright whereas inflorescences of plants of ‘Minnie Pearl’ faced outwardly.
    • 5. Inflorescences of plants of the new Phlox were rounded or dome-shaped whereas inflorescences of plants of ‘Minnie Pearl’ were flat-topped.
    • 6. Inflorescences of plants of the new Phlox had more flowers per inflorescence than plants of ‘Minnie Pearl’.
    • 7. Plants of the new Phlox had slightly smaller flowers than plants of ‘Minnie Pearl’.
    • 8. Plants of the new Phlox and ‘Minnie Pearl’ differed in flower color as plants of ‘Minnie Pearl’ had white-colored flowers.
    • 9. Plants of the new Phlox had shorter peduncles and pedicels than plants of ‘Minnie Pearl’.
Plants of the new Phlox can also be compared to plants of Phlox carolina ‘Kim’ , not patented. In side-by-side comparisons, plants of the new Phlox and ‘Kim’ differed in the following characteristics:
    • 1. Plants of the new Phlox were not as outwardly spreading as plants of ‘Kim’.
    • 2. Plants of the new Phlox had glossier and broader leaves than plants of ‘Kim’.
    • 3. Inflorescences of plants of the new Phlox were rounded or dome-shaped whereas inflorescences of plants of ‘Kim’ were open and ragged in appearance.
    • 4. Plants of the new Phlox and ‘Kim’ differed in flower color as plants of ‘Kim’ had light lilac-colored flowers.
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 on the first sheet comprises a side perspective view of typical flowering plants of ‘Aurora’.
The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘Aurora’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in one-gallon containers in a polyethylene-covered greenhouse and an outdoor nursery in Upper Tyrone Township, Pa. and under cultural practices typical of Phlox production.
