Description

Genus and species: Phlox paniculata hybid.

Variety denomination: ‘Purple Kiss’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of phlox, botanically known as Phlox paniculata, and hereinafter referred to by the cultivar name ‘Purple Kiss’. The new cultivar originated from an open pollination in 2005 in Haarlem, The Netherlands between unknown male and female Phlox paniculata plants.

The new cultivar was selected from the results of the open pollination in 2006 in Haarlem. The Netherlands and has been asexually reproduced through two generations by vegetative cuttings in Haarlem, The Netherlands since that time. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Haarlem, The Netherlands.

    • 1. Intense deep purple petals with pure white eye;
    • 2. Florets up to 4 cm in diameter;
    • 3. Compact habit;
    • 4. Healthy foliage; and
    • 5. Good mildew resistance.

DESCRIPTION OF PHOTOGRAPHS

This new phlox plant is illustrated by the accompanying photographs which show blooms and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 4-month-old plant grown in a greenhouse in Haarlem, The Netherlands.

FIG. 2 shows mature flowers.

FIG. 3 shows a mature leaf of the plant.

 DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Purple Kiss’. The data which define these characteristics were collected from asexual reproductions carried out in Haarlem, The Netherlands. The plant history was taken in August on 2-year-old plants which were planted and grown outdoors in daytime temperatures between 14° C. and 32° C. and nighttime temperatures between 5° C. and 15° C. No pinchings, growth retardants or photoperiodic treatments were used. Observations were made when the plants were in natural outdoor light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Purple Kiss’ differs from the commercial Phlox paniculata variety ‘Wilhelm Kesselring’ (unpatented), by having healthier foliage with thicker stems and a sturdier plant habit than ‘Wilhelm Kesselring’. Additionally, ‘Purple Kiss’ has a more compact plant habit and flowers that are larger and have a richer color than ‘Wilhelm Kesselring’.

‘Purple Kiss’ differs from the commercial Phlox variety ‘Grenadine Dream’ (U.S. Plant patent application Ser. No. 11/725,797), by having intense purple petals with a pure white eye while ‘Grenadine Dream’ has rich red-purple flowers.
