Abstract
A unique cultivar of Hybrid Creeping Phlox named ‘Rose Quartz’ characterized by vigorous, dense, spreading, multi-stemmed, winter-hardy habit with short, bright-green, shiny, linear leaves. Small flowers begin in mid-spring and continuing for up to six weeks in cooler weather conditions, on heavily-branched peduncles and completely cover the plant in peak season. Petals are rose-pink with a lighter center and a moderate notch and the tips of the petals. The new plant is able to withstand dry conditions once established, and the foliage stays clean and resists mildew. The new plant is especially suitable for the landscape as a potted plant and in the garden as a specimen or en masse.
Description
Botanical classification: Phlox hybrid.
Variety denomination: ‘Rose Quartz’.
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 Dec. 1, 2019. 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 Pleasant View Gardens/Proven Winners® on Jun. 15, 2020 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Phlox ‘Rose Quartz’ 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 to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.
The present invention relates to a new and distinct cultivar of Creeping Phlox plant known as Phlox ‘Rose Quartz’ and will be referred to hereafter by its cultivar name, ‘Rose Quartz’, or the “new plant”. The new plant was hybridized by the inventor at a wholesale perennial nursery in Zeeland, Mich. on Apr. 27, 2015 as a cross between Phlox subulata ‘Drummond's Pink’ (not patented) as the female or seed parent and the proprietary, unreleased, hybrid known by the breeder code 14-260-5 (not patented) as the male or pollen parent. The new plant passed initial evaluation on the spring of 2017 and was assigned the breeder code 15-130-1 through the remaining evaluation process. ‘Rose Quartz’ was first asexually propagated by stem cuttings in the greenhouses at the same nursery in Zeeland, Mich. in the summer of 2017. 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.
Phlox ‘Rose Quartz’ is unique from all other Creeping Phlox known to the inventor. The nearest comparison plants known to the inventor include: the female and male parents, ‘Ruby Riot’ copending U.S. Plant patent application Ser. No. 16/974,227, ‘Pink Sprinkles’ copending U.S. Plant patent application Ser. No. 16/974,294, ‘Majestic Magenta’ U.S. Plant patent application Ser. No. 16/974,098 ‘Barseventyfour’ U.S. Plant Pat. No. 23,564 and ‘Rocky Road Magenta’ U.S. Plant Pat. No. 31,485. The female parent, ‘Drummond's Pink’, has lighter pink flowers with rounded rather than emarginate petal apices. The male parent, 14-260-5, has flower petals that are more notched in the apex, the flower color is more lavender, the habit is taller, and the leaves broader. ‘Ruby Riot’ has a similar habit with flowers of reddish-pink and darker eyes. ‘Pink Sprinkles’ has larger flowers that are lighter baby pink in color. ‘Majestic Magenta’ has flowers that are more purplish-red hue. ‘Barseventyfour’ has a similar flower color, but the backs of the flowers and the front eye are darker. ‘Rocky Road Magenta’ has a smaller habit with slower spreading growth rate and the flowers vibrant magenta-purple flowers with small dark-purple eye.
Phlox ‘Rose Quartz’ differs from all other Phlox known to the inventor in the following repeatedly observed traits in combination:
-
- 1. Semi-vigorous plants of dense spreading habit, spreading by rooting stems, producing short, clean, bright-green, shiny, linear leaves;
- 2. Multiple heavily-branched stems produce branched panicles;
- 3. Flower beginning in mid-spring and continuing for up to six weeks, in cool conditions, completely covering plant at peak flowering;
- 4. Large flowers of rose-pink developing lighter eye and with moderate notches at the tip of the petals;
- 5. Plant is able to withstand dry conditions once established.
The photographs of the new plant demonstrate the unique traits of Phlox ‘Rose Quartz’ and the overall appearance of the plant at two-years-old growing in a full-sun trial garden in Zeeland, Mich. The colors in the drawings 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 ‘Rose Quartz’ 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 a partially shaded greenhouse or a full-sun trial garden of a wholesale perennial nursery in Zeeland, Mich. with supplemental fertilizer and water as needed.
