Phlox plant named `Lizzy`

Abstract

A distinct cultivar of Phlox plant named `Lizzy`, characterized by its upright and clumping plant habit; thick, leathery dark green leaves; distinctive red purple and white bi-colored salverform flowers; long flowering period; resistance to Powdery Mildew; and excellent garden performance.

Description

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 Lizzy.

The new Phlox was discovered by the Inventor in Rijpwetering, The Netherlands, in 1995 in a seed bed of sown Phlox paniculata seed from various crosses of unidentified Phlox seedling selections.

Asexual reproduction of the new cultivar by terminal cuttings taken at Rijpwetering, The Netherlands, 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 Lizzy have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Lizzy`. These characteristics in combination distinguish `Lizzy` as a new and distinct cultivar:

1. Upright and clumping plant habit.

2. Thick, leathery dark green leaves.

3. Distinctive red purple and white bi-colored salverform flowers.

4. Long flowering period, mid-summer through fall.

5. Resistance to Powdery Mildew.

6. Excellent garden performance; good weather tolerance.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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. The photograph comprises a top perspective view of a typical plant of the new Phlox in outdoor cultivation. Flower and foliage colors in the photograph may appear different than the actual colors due to light reflectance.
