plant named ‘Magenta Pearl’
A new and unique cultivar of garden Phlox named Phlox plant ‘Magenta Pearl’ multi-stemmed, short, upright, slowly-spreading habit with clean green, glossy, lanceolate leaves with exceptional powdery mildew resistance. Foliage is thick on stiff, upright stems. Faint to lightly sweet fragrant flowers of deep magenta-pink faces with light pink halo and darker eye zones midribs are produced on multiple branched peduncles and cover the top of the plant beginning early summer about two weeks prior typical Phlox paniculata cultivars. ‘Magenta Pearl’ is especially suitable as a potted plant, for the garden, for attracting hummingbirds and butterflies, and for cut flower arrangements.

Botanical classification: Phlox hybrid.
Variety denomination: ‘Magenta Pearl’.STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)
The first non-enabling disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 1, 2020. Subsequently, the new plant was advertised in the “Walters Gardens 20-21 Catalog” by Walters Gardens, Inc. released on May 20, 2020. The claimed plant was first sold to the public on Jul. 13, 2020 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Phlox ‘Magenta Pearl’ have been sold to the public in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to 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 ‘Magenta Pearl’ and will be referred to hereafter by its cultivar name or the “new plant”. The new plant was the result of a cross of Phlox ‘Amethyst Pearl’ U.S. Plant Pat. No. 28,487 as the female or seed parent times the male or pollen parent Phlox carolina ‘Lil' Cahaba’ (not patented) performed at a wholesale perennial nursery in Zeeland, Mich. Nov. 17, 2014. The new plant was initially given the breeder code 14-24-3 throughout subsequent evaluations at the same nursery. ‘Magenta Pearl’ has been asexually propagated by 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 ‘Magenta Pearl’ is unique from its parents and all other tall garden Phlox or other Phlox known to the inventor. The new plant differs from the female parent ‘Amethyst Pearl’ in that the female parent has a slightly shorter habit with light amethyst-colored flowers. The male parent is shorter in habit with narrower foliage and deeper magenta flowers.
The closest comparison cultivars known to the inventor are ‘Fashionable Early Flamingo’ U.S. Plant Pat. No. 29,911, ‘Fashionable Early Princess’ U.S. Plant Pat. No. 28,680, ‘Kung Fuchsia’ U.S. Plant Pat. No. 31,308, ‘Forever Pink’ U.S. Plant Pat. No. 24,918, ‘Opening Act Ultrapink’ U.S. Plant Pat. No. 32,093 and ‘Minnie Pearl’ (not patented). ‘Fashionable Early Flamingo’ has a taller and broader habit and flowers of light lavender-pink. ‘Fashionable Early Princess’ has a larger, broader and taller habit with flowers of light fuchsia-pink. ‘Forever Pink’ is shorter in habit and lighter pink in flower color. ‘Kung Fuchsia’ has a shorter habit with flowers of intense, bright, fuchsia-pink. ‘Opening Act Ultrapink’ has slightly lighter pink flowers of fluorescent rose-pink and the flower is slightly larger with a wider face. ‘Minnie Pearl’ has a slightly shorter habit and flowers of pure white.
‘Magenta Pearl’ is distinct from all other Phlox known to the inventor in the following repeatedly-observed combination of traits:
- 1. Plants of medium upright habit, slowly spreading by short rhizomes, producing clean, glossy, clean green, lanceolate leaves;
- 2. Showing exceptional powdery mildew resistance;
- 3. Multiple branched, stems produce rounded mounds of early flowers;
- 4. Faint to lightly sweet fragrant flowers on strong stiff stems of about 47.0 cm tall producing deep magenta-pink flower faces with light pink halo and darker eye zones midrib markings;
- 5. Flowers cover 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.
The photographs of the new plant demonstrate the unique traits of ‘Magenta Pearl’ and the overall appearance of the plant at three-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.
The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Phlox ‘Magenta Pearl’ 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 to four-year-old plants in the full sun trial garden of a wholesale perennial nursery in Zeeland, Mich. with supplemental fertilizer and water as needed.
