USPP32287P2 - Phlox plant named ‘Uptown Girl’ - Google Patents

Abstract

A new and unique hybrid cultivar of Phlox plant named ‘Uptown Girl’ of medium-height, multi-stemmed, upright, compact habit. Foliage is thick with good powdery mildew resistance on stiff stems. Flowers are light pink flowers with dark pink star-shaped center eye produced on large heads of branched peduncles and nearly cover the top of the plant beginning mid-July and continuing and reblooming for about six weeks through late summer. ‘Uptown Girl’ is especially suitable as a potted plant, for the garden, for attracting hummingbirds and butterflies, and for cut flower arrangements.

Description

Botanical classification: Phlox paniculata.

Variety denomination: ‘Uptown Girl’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling disclosure, in the form of a website with a photograph and brief description was on Feb. 1, 2019 maintained by Walters Gardens, Inc. Subsequently, Walters Gardens, Inc. published an advertisement in their “Walters Gardens 19-20 Catalog” on May 29, 2019, and first sold the new plant on Jul. 8, 2019. Walters Gardens, Inc. obtained the new plant and all information relating thereto, from the inventor. No plants of Phlox ‘Uptown Girl’ have been sold, in this country or anywhere in the world, under this or any name, nor has any disclosure of the new plant been made more than one year prior the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Tall Phlox cultivar known as Phlox ‘Uptown Girl’ and will be referred to hereafter by its cultivar name or the “new plant”. The new plant was the result of a controlled pollination of the proprietary, unreleased, hybrid known only as 2013-PHL-AA-42 (not patented) as the female or seed parent and the proprietary, unreleased hybrid known only as 2013 PHL-13-AA (not patented) as the male or pollen parent. The cross was performed by the inventor on Aug. 7, 2014 in the greenhouses at a wholesale perennial nursery in Zeeland, Mich., and seed was collected in the autumn of 2014. During the trial process the new plant arising as a single seedling selection from the identified cross was identified by the breeder code 14-599-3. ‘Uptown Girl’ has been asexually propagated by tip and basal stem cuttings in the greenhouses at the same nursery in Zeeland, Mich. since 2016, as well as by shoot tip tissue culture. The unique characteristics of the new plant have been found to be reproducible and stable in successive generations of asexually propagated plants and the resultant plants have been found to be identical to the original selection.

BRIEF SUMMARY OF THE PLANT

Phlox ‘Uptown Girl’ is unique from its parents and all other tall garden Phlox or other hybrid Phlox known to the inventor. The closest comparison cultivars known to the inventor are ‘Ditosmel’ U.S. Plant Pat. No. 20,593 ‘Bright Eye’ (not patented) and ‘Ditopiwi’ U.S. Plant Pat. No. 31,360. ‘Ditosmel’ has smaller flower heads with petals that weakly overlap and have a deeper pink coloration than the pinkish-lavender petals of the new plant. ‘Bright Eye’ has less overlapping petals of deeper pink with defused dark pink eye. ‘Ditopiwi’ has smaller inflorescences of fewer and larger flowers. The new plant may also be compared with ‘Glamour Girl’ U.S. Plant Pat. No. 25,778 which has a similar habit and plants size, but the flowers are hot coral pink. Copending U.S. Plant patent application Ser. No. 16/873,088 ‘Cover Girl’ has a slightly taller habit and lavender-purple flowers. Copending U.S. Plant patent application Ser. No. 16/873,087 ‘Party Girl’ has a slightly shorter habit with flowers that are white with a light pink center eye.

‘Uptown Girl’ differs from all other Phlox known to the inventor in the following repeatedly observed traits in combination:

• • 1. Medium to tall height plants of upright habit, producing clean, medium-green, lanceolate leaves;
  • 2. Showing good powdery mildew resistance;
  • 3. Multiple stems produce large branched mounds of flowers starting in mid-July for about six weeks;
  • 4. Light pink flowers with dark pink star-shaped center eye on strong stiff stems;
  • 5. Flowers cover nearly the entire top of the plant;

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of ‘Uptown Girl’ and the overall appearance of three-year-old plants grown in a full sun trial garden in Zeeland, Mich. 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.
