plant named ‘Baby Doll Pink’

Abstract

A new and unique cultivar of garden phlox named Phlox ‘Baby Doll Pink’ multi-stemmed, very short, upright, slowly-spreading habit with clean, medium-green, glossy, lanceolate leaves with exceptional powdery mildew resistance. Foliage is thick with stiff stems. Flowers are medium pink with white eye zone markings produced on branched peduncles and nearly cover the top of the plant beginning early summer, about two weeks prior typical Phlox paniculata cultivars and continuing for about six weeks. ‘Baby Doll Pink’ is especially suitable as a potted plant, for the garden, for attracting hummingbirds and butterflies, and for cut flower arrangements.

Description

Botanical classification: Phlox hybrid.

Variety denomination: ‘Baby Doll Pink’.

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

The first disclosure, in the form of a sale, was made by Walters Gardens, Inc. on Jul. 16, 2018 to Sheridan Nurseries. Subsequently, Walters Gardens, Inc. also sold the new plant to Willoway Nurseries, Inc. on Aug. 8, 2018, to Prides Corner Farms on Aug. 13, 2018 and to Overdevest Nurseries, L.P. on Aug. 20, 2018. Walters Gardens, Inc. obtained the new plant and all information relating thereto, from the inventor. No plants of Phlox ‘Baby Doll Pink’ have been sold, in this country or anywhere in the world, 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 cultivar of Phlox plant, known as Phlox ‘Baby Doll Pink’ and will be referred to hereafter by its cultivar name or the “new plant”. The new plant was the result of an insect pollination in an isolation block of a proprietary, unreleased, unnamed hybrid identified by the breeder code 13-496-1 and a sibling of 13-496-1. The exact male parent is unknown. The female parent was grown in trial isolation block at a wholesale perennial nursery in Zeeland, Mich., and seed was collected in the fall of 2014. During the trial process the new plant was identified by the breeder code 14-663-1. ‘Baby Doll Pink’ has been asexually propagated by tip and basal stem cuttings in the greenhouses at the same nursery in Zeeland, Mich. since 2016. 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 ‘Baby Doll Pink’ is unique from its parents and all other tall garden phlox or other hybrid Phlox known to the inventor. The new plant differs from the female parent in that the female parent is taller and has different colored flowers. Comparison with the male parent is not possible. The most closely comparison cultivars known to the inventor are Phlox ‘Cloudburst’ U.S. Plant Pat. No. 30,289, ‘Kung Fuchsia’ U.S. Plant patent application Ser. No. 16/501,030, ‘Opening Act Blush’ U.S. Plant Pat. No. 27,462, ‘Forever Pink’ U.S. Plant Pat. No. 24,918, ‘Fashionably Early Flamingo’ U.S. Plant Pat. No. 29,911 and ‘Fashionably Early Princess’ U.S. Plant Pat. No. 28,680. ‘Cloudburst’ is much taller in habit and has more lavender purple flowers with bright pink eyes. ‘Kung Fuchsia’ is taller in habit, thicker foliage and has flowers that are bright fuchsia with a light pink eye zone. ‘Opening Act Blush’ has a slightly taller habit with smaller, light lavender-pink flowers. ‘Forever Pink’ has a shorter flower season smaller, darker pink flowers without the white eye, and the habit is taller. ‘Fashionably Early Flamingo’ has taller and broader habit with larger foliage and larger inflorescence and the flower lacks the white eye. ‘Fashionably Early Princess’ has fragrant flowers of light fuchsia-pink with a darker eye on taller plants. ‘Amethyst Pearl’ U.S. Plant Pat. No. 28,487 has light amethyst-pink flowers and taller habit. ‘Minnie Pearl’ (not patented) has white flowers and taller habit. ‘Lil' Cahaba’ (not patented) has a taller habit with pinky mauve flowers. ‘David's Lavender’ U.S. Plant Pat. No. 17,793 is taller with lavender flowers. ‘Baby Doll Pink’ differs from all other phlox known to the inventor in the following repeatedly observed traits in combination:

• • 1. Plants of short upright habit, slowly spreading by short rhizomes, producing clean, glossy, medium-green, lanceolate leaves;
  • 2. Showing exceptional powdery mildew resistance;
  • 3. Multiple branched, stems produce rounded mounds of flowers starting early in the season;
  • 4. Flower on strong stiff stems of about 28.0 cm tall producing medium pink flower faces with small white eye zones;
  • 5. Flowers cover nearly the entire top of the plant;
  • 6. Flowering beginning in early-summer about two weeks prior to typical Phlox paniculata cultivars and re-blooming through late-summer.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of ‘Baby Doll Pink’ and the overall appearance of the plant at two-years-old 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.
