Abstract

A new and distinct cultivar of Phlox plant named ‘Junior Bouquet’, characterized by its upright and compact plant habit; freely basally branching habit and short internodes; dense and bushy growth habit; attractive dark pink-colored flowers with red purple-colored centers; freely and continuous flowering habit; resistance to Powdery Mildew; and good garden performance.

Description

Botanical classification/cultivar designation: Phlox paniculata cultivar Junior Bouquet.

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 Junior Bouquet.

The new Phlox is a product of a planned breeding program conducted by the Inventor in Zwaanshoek, The Netherlands. The objective of the breeding program was to create new compact Phlox cultivars with attractive flower coloration and resistance to Powdery Mildew.

The new Phlox originated from a cross-pollination made by the Inventor in 1996 in Zwaanshoek, The Netherlands of a proprietary selection of Phlox paniculata identified as code number 95.05.28, not patented, as the female, or seed, parent with a proprietary selection of Phlox paniculata identified as code number 95.05.07, not patented, as the male, or pollen, parent. The new Phlox was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Zwaanshoek, The Netherlands in 1998.

Asexual reproduction of the new cultivar by terminal cuttings at Zwaanshoek, The Netherlands since 1998, 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 cultivar Junior Bouquet have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Junior Bouquet’. These characteristics in combination distinguish ‘Junior Bouquet’ as a new and distinct cultivar of Phlox.

- 1. Upright and compact plant habit.
- 2. Freely basally branching habit and short internodes; dense and bushy growth habit.
- 3. Attractive dark pink-colored flowers with red purple-colored centers.
- 4. Freely and continuous flowering habit.
- 5. Resistant to Powdery Mildew.
- 6. Good garden performance.

Plants of the new Phlox differ primarily from plants of the parent selections in plant habit as plants of the new Phlox are more compact than plants of the parent selections. In addition, plants of the new Phlox and the female parent selection differ in flower coloration.

Plants of the new Phlox can be compared to the Phlox paniculata cultivar Rijnstroom, not patented. In side-by-side comparisons conducted in Zwaanshoek, The Netherlands, plants of the new Phlox differed from plants of the cultivar Rijnstroom in the following characteristics:

- 1. Plants of the new Phlox were more compact than plants of the cultivar Rijnstroom.
- 2. Plants of the new Phlox had shorter internodes than plants of the cultivar Rijnstroom.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 more accurately describe the actual colors of the new Phlox.

The photograph on the first sheet is a close-up view of a typical inflorescence of ‘Junior Bouquet’.

The photograph on the second sheet is a close-up view of a typical flowering branch of ‘Junior Bouquet’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown in 't Zand, The Netherlands, in an outdoor nursery and under commercial production practices during the summer. Plants were about 13 weeks old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 5 to 20° C. and night temperatures ranged from 2 to 12° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
