STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

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

The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Hillegom, The Netherlands. The objective of the breeding program was to create new uniform and freely flowering Phlox plants with unique and attractive leaf and flower coloration.

The new Phlox plant originated from an open-pollination in 2012 in Hillegom, The Netherlands, of Phlox paniculata ‘Pixie Miracle’, not patented, as the female, or seed, parent with an unknown Phlox paniculata seedling selection as the male, or pollen, parent. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Hillegom, The Netherlands in July, 2014.

Asexual reproduction of the new Phlox plant by vegetative cuttings in a controlled greenhouse environment in Hillegom, The Netherlands since February, 2015, 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 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 ‘Olympus’. These characteristics in combination distinguish ‘Olympus’ as a new and distinct Phlox plant:

• • 1. Broadly upright plant habit.
  • 2. Freely branching habit.
  • 3. Thick green and light yellow variegated leaves that are tinged with red.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Relatively large purple-colored flowers with white-colored centers.
  • 7. Good garden performance.

Plants of the new Phlox differ primarily from plants of the female parent, ‘Pixie Miracle’, in the following characteristics:

• • 1. Plants of the new Phlox are taller than plants of ‘Pixie Miracle’.
  • 2. Plants of the new Phlox are more freely branching than plants of ‘Pixie Miracle’.
  • 3. Leaves of plants of the new Phlox are green and yellow variegated and tinged with red in color whereas leaves of plants of ‘Pixie Miracle’ are solid green in color.
  • 4. Flowers of plants of the new Phlox are purple in color with white-colored centers whereas flowers of plants of ‘Pixie Miracle’ are lavender in color with bright white-colored centers.

Plants of the new Phlox can also be compared to plants of Phlox paniculata ‘Nora Leigh’, not patented. In side-by-side comparisons conducted in Hillegom, The Netherlands, plants of the new Phlox and ‘Nora Leigh’ differed primarily in the following characteristics:

• • 1. Plants of the new Phlox are shorter than plants of ‘Nora Leigh’.
  • 2. Leaves of the new Phlox are thicker than leaves of plants of ‘Nora Leigh’.
  • 3. Leaves of plants of the new Phlox are green and yellow variegated and tinged with red in color whereas leaves of plants of ‘Nora Leigh’ are green and white variegated in color.
  • 4. Flowers of the new Phlox are larger than flowers of plants of ‘Nora Leigh’.
  • 5. Flowers of plants of the new Phlox are purple in color with white-colored centers whereas flowers of plants of ‘Nora Leigh’ are white in color with pinkish red-colored centers.
