Botanical denomination: Clematis hybrid.
Cultivar designation: ‘Rain Dance’.STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)
The first public disclosure of the claimed plant, in the form of a sale, was made by Walters Gardens, Inc. Oct. 5, 2020 to Hoover's Greenhouse, Farmer Bailey and Vermont Wildflower Farm. No plants were in condition to sell prior to Oct. 5, 2020. Prior to that, on Feb. 1, 2020 the claimed plant was displayed with a non-enabling photograph and brief description in a website operated by Walters Gardens, Inc., and on May 21, 2020 as a non-enabling photograph and brief description in the 2020-2021 Catalog by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Clematis ‘Rain Dance’ were in condition to sell prior to the first sale, nor 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 plant of herbaceous type Clematis. The new plant is the result of a single seedling selection from a cross between an unnamed, proprietary selection of a Clematis fremontii x Clematis integrifolia cross (not patented) as the female parent times ‘Ashva’ (not patented). The cross was performed on Jun. 16, 2014 by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA. The new plant passed the original evaluation in summer of 2016 at the same nursery in Zeeland, Mich., and was the assigned the breeder code 14-5-1 during these remaining trials. The new plant was selected from among many other seedlings growing at the same nursery in Zeeland, Mich. which met the rigorous criteria of excellent flowers, foliage and habit established as breeding goals.
‘Rain Dance’ has been asexually propagated since 2016 by shoot tip cuttings at the same nursery in Zeeland, Mich. The resultant asexually propagated plants have remained stable and exhibit the identical characteristics as the original plant in multiple generations.BRIEF SUMMARY OF THE INVENTION
‘Rain Dance’ differs from all other Clematis known to the applicant. The nearest known cultivars are Clematis ‘Center Star’ U.S. Plant Pat. No. 17,010, ‘Cleminov 51’ U.S. Plant Pat. No. 17,012, ‘Stand by Me’ U.S. Plant Pat. No. 30,556, ‘Violet Stardust’ U.S. Plant Pat. No. 30,555, Clematis x durandii (not patented) ‘Stand by Me Lavender’ copending U.S. Plant Patent Application.
‘Center Star’ is shorter than the new plant, the flowers are flatter and more upright, with typically five tepals that are less recurved and more purple-blue in color. ‘Cleminov 51’ is shorter in habit and has darker colored violet-purple flowers, more recurved tepals. ‘Violet Stardust’ has a similar habit and the smaller flowers are more violet-blue. The x durandii forms are not as tall and not as floriferous. ‘Stand by Me’ has a shorter habit with foliage having a more purplish-bronze cast to the back of the foliage when young and more bell-shaped flowers with violet-blue tepals. ‘Stand by Me Lavender’ has a shorter habit with more dusty lavender flowers.
The new plant is taller than the female parent, more floriferous and more vigorous than both the female and male parents and the flowers are more bell-shaped. ‘Ashva’ is has a taller, vining, woody habit, and the flowers are larger with broader ruffled tepals typically of five to six that are violet purple on the margins with a reddish purple center bar.
The new plant, ‘Rain Dance’, differs from all Clematis known to the inventor in the following combined traits:
- 1. The foliage is both ovate and trifoliate, and micro-tomentose below and glabrous above;
- 2. Outwardly-facing flowers begin in early spring to June with rebloom in the late summer typically having four tepals per flower;
- 3. Large outwardly-facing flowers of indigo-blue tepals develop;
- 4. Plant habit is intermediate in height, benefits from stakes or other nearby plants when mature.
The photographs of the new plant demonstrate the overall appearance of trial garden at a wholesale perennial nursery in Zeeland, Mich., USA. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.
The following description is based on a five-year-old plant growing in a full-sun trial garden with supplemental water and fertilizer at a wholesale perennial nursery in Zeeland, Mich., USA. The new plant has not been grown under all possible environments and may phenotypically appear different under different conditions such as light, temperatures, fertilizer, and water, without any difference in genotype. The color descriptions are from the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
