Abstract

A new and distinct cultivar of Phlox plant named ‘Alexandra’, characterized by its upright plant habit; freely flowering habit; dark pink and white bi-colored flowers; and good cut flower and garden performance.

Description

Botanical designation: Phlox paniculata.
Cultivar denomination: ‘Alexandra’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Phlox, botanically known as Phlox paniculata and hereinafter referred to by the name ‘Alexandra’.
The new Phlox originated from a cross-pollination of two unnamed proprietary selections of Phlox paniculata, not patented. The new Phlox was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Hillegom, The Netherlands in July, 2004.
Asexual reproduction of the new Phlox by cuttings in a controlled greenhouse environment in Haarlem, The Netherlands since 2006, has shown that the unique features of this new Phlox 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 environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Alexandra’. These characteristics in combination distinguish ‘Alexandra’ as a new and distinct cultivar of Phlox:
    • 1. Upright plant habit.
    • 2. Freely flowering habit.
    • 3. Dark pink and white bi-colored flowers.
    • 4. Good cut flower and garden performance.
Plants of the new Phlox and the parent selections differ primarily in plant height and flower color.
Plants of the new Phlox can also be compared to plants of Phlox paniculata ‘Laura’, not patented. In side-by-side comparisons conducted in Hillegom, The Netherlands, plants of the new Phlox and ‘Laura’ differed primarily in flower color as plants of ‘Laura’ had lilac and white bi-colored flowers. In addition, plants of the new Phlox were taller than plants of ‘Laura’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Phlox, 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.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Alexandra’ grown in a container.
The photograph at the top of the second sheet is a close-up view of typical flowers of ‘Alexandra’.
The photograph at the bottom of the second sheet is a close-up view of a typical leaves of ‘Alexandra’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in Hillegom, The Netherlands, under commercial practice during the late summer and early autumn in an outdoor nursery with day temperatures ranging from 14° C. to 32° C. and night temperatures ranging from 5° C. to 15° C. Plants had been growing for two years when the photographs and description were taken.
