plant named ‘Glamour Girl’

Abstract

A new and unique plant cultivar of Tall Garden Phlox, Phlox paniculata, named ‘Glamour Girl’ that has powdery mildew resistant leaves, sweet-smelling, densely packed, hot-coral-pink flowers on broad strong panicles, especially suitable in the garden as a specimen or en masse, potted plant or patio, for color, fragrance and attracting hummingbirds and butterflies, and for cut flower arrangements.

Description

Botanical classification: Phlox paniculata.

Variety denomination: ‘Glamour Girl’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Tall Garden Phlox botanically known as Phlox paniculata, and hereinafter referred to by the cultivar name ‘Glamour Girl’. The new variety originated from a crossing made by the inventor, Kevin A. Hurd on Jun. 26, 2007 at a nursery in Zeeland, Mich., USA between the female parent Phlox paniculata ‘Junior Bouquet’ U.S. Plant Pat. No. 16,865 and the male parent ‘Wendy House’ U.S. Plant Pat. No. 18,158 with seed harvested Sep. 5, 2007. The new plant originally was designated under the breeder code 07-23-01 with final evaluations approved in the summer of 2012.

Phlox paniculata ‘Glamour Girl’ has been asexually propagated by stem cuttings at the same nursery in Zeeland, Mich. The unique characteristics of the new plant have been found to be reproducible and stable in successive generations of asexual propagation and the resultant plants have been found to be identical to the original selection. The present invention has been found to retain its distinctive characteristics through successive asexual propagations via vegetative cuttings.

SUMMARY OF THE INVENTION

Phlox paniculata ‘Glamour Girl’ is unique from all other Tall Garden Phlox known to the inventor. The closest comparison varieties are Phlox ‘Junior Bouquet’ U.S. Plant Pat. No. 16,865, ‘Wendy House’ U.S. Plant Pat. No. 18,158 and ‘Junior Dance’ U.S. Plant Pat. No. 16,059. ‘Glamour Girl’ is similar to ‘Wendy House’ in its upright, compact and freely basal branching plant habit but the new plant has hot coral pink rather than dark purple-colored flowers. In comparison to ‘Junior Bouquet’ and ‘Junior Dream’, the former has flowers that are a much lighter pink, and the latter has flowers that are more salmon and not as deeply colored as the instant plant. The new plant ‘Glamour Girl’ differs from these cultivars and all other Tall Garden Phlox known to the inventor in the following repeatedly observed traits in combination:

• • 1. Bright-green, powdery mildew-resistant foliage on tall stems 45 to 50 cm tall.
  • 2. Large flowers of hot coral-pink with darker eye on large, strong, upright, dense panicles.
  • 3. Hardy vigorous growth habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of Phlox ‘Glamour Girl’ and the overall appearance of the plant at two-years old. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.

FIG. 1 shows the new plant growing in an outdoor full-sun trial bed in mid-flowering season with clean, disease-free foliage.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Phlox paniculata ‘Glamour Girl’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are based on two-year old plants in the full sun trial garden of a wholesale nursery in Zeeland, Mich. with supplemental fertilizer and water as needed and also a partially shaded greenhouse for color comparison, in particular of the flower.
