Description

Botanical denomination: Clematis hybrid.

Cultivar designation: ‘Stand by Me Lavender’.

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. on Sep. 27, 2021 to Corso's Flower Farm, Romance Gardens, Weakland Greenhouse and Baileys Nursery. Prior to that, on Dec. 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, 2021 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 ‘Stand by Me Lavender’ 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 bush-type Clematis. The seed producing the new plant was collected by the inventor from a research garden bed at a wholesale nursery in Zeeland, Mich., USA on Aug. 27, 2014. The seed was from a selected, ‘Stand by Me’ U.S. Plant Pat. No. 30,556 as the female parent, times ‘Rose Colored Glasses’ (not patented) as the male parent. The new plant passed the original evaluation in summer of 2016 at a wholesale perennial nursery in Zeeland, Mich., USA and was the subject of the subsequent further evaluations and given the breeder code 14-129-1 during these 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 foliage and habit established as breeding goals.

‘Stand by Me Lavender’ 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 successive generations.

BRIEF SUMMARY OF THE INVENTION

‘Stand by Me Lavender’ differs from all other Clematis known to the applicant. The nearest known cultivars are Clematis ‘Center Star’ U.S. Plant Pat. No. 17,010, ‘New Love’ U.S. Plant Pat. No. 13,977 and ‘Stand by Me’ U.S. Plant Pat. No. 30,556. ‘Center Star’ is slightly taller than the new plant, the flowers are more upright, less drooping with typically five tepals that are less recurved and more purple in color. ‘New Love’ is shorter in habit and has lighter-colored, outwardly, verticillate flowers. ‘Stand by Me’ has a taller and denser habit with foliage having a purplish bronze cast to the back of the foliage when young and violet-blue tepals.

The female parent is more dense with violet-blue flowers. The male parent has pink flowers with foliage that is longer, lighter green and narrower without the bronze on the underside. The new plant is more vigorous than both the parents.

The new plant, ‘Stand by Me Lavender’, differs from all Clematis known to the inventor in the following combined traits:

• • 1. The foliage is ovate and micro-tomentose below and glabrous above;
  • 2. Multiple nodding flowers per node begin in late May to June with rebloom in the late summer typically having four tepals per flower;
  • 3. Flowers of reflexed lavender-purple tepals develop from dark purple buds;
  • 4. Plant habit is generally short, compact, upright and non-vining but benefits from stakes or other nearby plants when mature.

BRIEF DESCRIPTION OF THE DRAWINGS

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.

DETAILED BOTANICAL DESCRIPTION

The following description is based on a three-year-old plant growing in a full-sun trial garden with supplemental water and fertilizer at a wholesale perennial nursery in Zeeland, Mich., USA.
