USPP28681P2 - Phlox plant named ‘Barphspribluimp’ - Google Patents

Abstract

A new and distinct cultivar of Phlox plant named ‘Barphspribluimp’, characterized by its upright, outwardly spreading and mounding plant habit; vigorous growth habit; early and freely flowering habit; light violet blue-colored flowers with darker-colored centers; and good garden performance.

Description

Botanical designation: Phlox subulata.

Cultivar denomination: ‘BARPHSPRIBLUIMP’.

BACKGROUND OF THE INVENTION

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

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 attractive flower color.

The new Phlox plant originated from a cross-pollination made by the Inventor in April, 2011 in Aalsmeer, The Netherlands, of a proprietary selection of Phlox subulata identified as code number SB-0099, not patented, as the female, or seed, parent with a proprietary selection of Phlox subulata identified as code number SB007-000016-001, 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 April, 2012.

Asexual reproduction of the new Phlox plant by cuttings in a controlled environment in Aalsmeer, The Netherlands since June, 2012 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 ‘Barphspribluimp’. These characteristics in combination distinguish ‘Barphspribluimp’ as a new and distinct Phlox plant:

• • 1. Upright, outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Light violet blue-colored flowers with darker-colored centers.
  • 5. Good garden performance.

Plants of the new Phlox differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have light pink-colored flowers.

Plants of the new Phlox differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Phlox flower earlier than plants of the male parent selection.
  • 2. Plants of the new Phlox and the male parent selection differ in flower color as flowers of plants of the male parent selection have light blue-colored flowers with pale blue-colored centers.
  • 3. Plants of the new Phlox are more low temperature-tolerant than plants of the male parent selection.

Plants of the new Phlox can be compared to plants of Phlox subulata ‘Emerald Cushion Blue’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Emerald Cushion Blue’ differ in the following characteristics:

• • 1. Plants of the new Phlox are slightly smaller than plants of ‘Emerald Cushion Blue’.
  • 2. Plants of the new Phlox are more freely flowering than plants of ‘Emerald Cushion Blue’.
  • 3. Plants of the new Phlox and ‘Emerald Cushion Blue’ differ in flower color as plants of ‘Emerald Cushion Blue’ have light violet-colored flowers.

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 plant of ‘Barphspribluimp’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the spring in 13-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Phlox production. During the production of the plants, day temperatures averaged 14° C. and night temperatures averaged 5° C. Plants were pinched one time and were ten 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.
