plant named ‘Versoldpink’

Abstract

A new and distinct cultivar of Phlox plant named ‘Versoldpink’, characterized by its upright and relatively compact plant habit; freely flowering habit; large inflorescences with red purple, purple and white-colored flowers; long flowering period; good garden performance and resistance to Powdery Mildew.

Description

Botanical designation: Phlox paniculata.

Cultivar denomination: ‘VERSOLDPINK’.

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 name ‘Versoldpink’.

The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Haarlem, The Netherlands. The objective of the breeding program was to create new compact and freely-flowering Phlox plants with attractive flower colors.

The new Phlox plant originated from a cross-pollination made by the Inventor in 2007 in Haarlem, The Netherlands, of two unnamed seedling selections of Phlox paniculata, not patented. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Haarlem, The Netherlands in 2009.

Asexual reproduction of the new Phlox plant by cuttings in a controlled environment in Haarlem, The Netherlands since 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 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 ‘Versoldpink’. These characteristics in combination distinguish ‘Versoldpink’ as a new and distinct Phlox plant:

• • 1. Upright and relatively compact plant habit.
  • 2. Freely flowering habit.
  • 3. Large inflorescences with red purple, purple and white-colored flowers.
  • 4. Long flowering period.
  • 5. Good garden performance.
  • 6. Resistance to Powdery Mildew.

Plants of the new Phlox and the parent selections differ primarily in the following characteristics:

• • 1. Plants of the new Phlox are shorter and more compact than plants of the parent selections.
  • 2. Plants of the new Phlox and the parent selections differ in inflorescence shape.
  • 3. Plants of the new Phlox are stronger and more resistant to Powdery Mildew than plants of the parent selections.

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

• • 1. Plants of the new Phlox were shorter and more compact than plants of ‘Anastasia’.
  • 2. Plants of the new Phlox were more freely flowering than plants of ‘Anastasia’.
  • 3. Plants of the new Phlox had larger inflorescences than plants of ‘Anastasia’.

The photograph on the second sheet is a close-up view of a typical flower of ‘Versoldpink’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer and early autumn in 1.5-liter containers in an outdoor nursery in Haarlem, The Netherlands and under cultural practices typical of commercial Phlox production.
