plant named ‘Barseventynine’

Abstract

A new and distinct cultivar of Phlox plant named Barseventynine, characterized by its upright and tall plant habit; vigorous growth habit; freely flowering habit; large pyramidal inflorescences with light red purple-colored flowers with darker red purple-colored centers; and good cut flower performance.

Description

Botanical designation: Phlox paniculata.

Cultivar denomination: ‘BARSEVENTYNINE ’.

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 ‘Barseventynine’.

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

The new Phlox plant originated from a cross-pollination made by the Inventor in 2008 in Aalsmeer, The Netherlands, of a proprietary selection of Phlox paniculata identified as code number 03-066-04, not patented, as the female, or seed, parent with a proprietary selection of Phlox paniculata identified as code number BS999, not patented, 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 cross-pollination in a controlled environment in Aalsmeer, The Netherlands in 2010.

Asexual reproduction of the new Phlox plant by cuttings in a controlled environment in Aalsmeer, The Netherlands since 2010 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 ‘Barseventynine’. These characteristics in combination distinguish ‘Barseventynine’ as a new and distinct Phlox plant:

• • 1. Upright and tall plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely flowering habit.
  • 4. Large pyramidal inflorescences with light red purple-colored flowers with darker red purple-colored centers.
  • 5. Good cut flower performance.

Plants of the new Phlox and the parent selections differ primarily in the growth habit, inflorescence shape and flower color.

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

• • 1. Plants of the new Phlox were taller than plants of ‘Bright Eyes’.
  • 2. Plants of the new Phlox flowered earlier than plants of ‘Bright Eyes’.
  • 3. Plants of the new Phlox and ‘Bright Eyes’ differed in inflorescence shape as plants of ‘Bright Eyes’ had more conical-shaped inflorescences.
  • 4. Plants of the new Phlox and ‘Bright Eyes’ differed slightly in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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 photograph 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 comprises a side perspective view of typical flowering stem of ‘Barseventynine’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the late summer and early autumn in 17-cm containers in a glass-covered greenhouse in Aalsmeer, The Netherlands and under cultural practices typical of commercial cut flower Phlox production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 17° C. Plants were four months old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
