USPP32023P2 - Allium plant named ‘Serendipity’ - Google Patents

Abstract

A new and distinct cultivar of ornamental onion, Allium plant named ‘Serendipity’, with compact, medium-sized habit, heavily-glaucous, upright, stiff, strap-like, blue-green foliage without twisting, and numerous, tightly-clustered, reddish-purple flowers forming in globose umbels over a long period beginning in late July.

Description

Botanical classification: Allium hybrid (Linnaeus).

Variety denomination: ‘Serendipity’.

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

The first public 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, 2019. The claimed plant was first sold on Feb. 4, 2019 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Allium ‘Serendipity’ 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.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct ornamental onion, Allium ‘Serendipity’ was discovered by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as non-induced, sport mutation from Allium ‘Millenium’ in Sep. 13, 2012. The new plant was divided from the mother plant the same time.

Allium ‘Serendipity’ has been successfully asexually propagated by garden bulb division method since 2014 at a wholesale perennial nursery in Zeeland, Mich. and found to be stable and produce identical plants that maintain the unique characteristics of the original plant through multiple generations.

SUMMARY OF THE PLANT

Allium ‘Serendipity’ differs from its sport parent as well as all other ornamental onion known to the applicant. The most similar known Allium cultivars are: ‘Medusa’ U.S. Plant Pat. No. 28,701, Allium senescens ‘Blue Eddy’ (not patented), Allium tanguticum ‘Summer Beauty’ (not patented), ‘Lavender Bubbles’ U.S. Plant Pat. No. 31,126, and ‘Millenium’ (not patented). ‘Blue Eddy’ has shorter and more twisted leaves, flowers and overall habit and smaller flower globes and lighter colored flowers. ‘Summer Beauty’ has less glaucous foliage, lighter flowers in larger umbels and produces no seed. ‘Lavender Bubbles’ is slightly shorter in habit, blooms later with darker purple flowers and has more twisted foliage. ‘Millenium’ has foliage that is less glaucous blue-green.

Allium ‘Serendipity’ differs from these above cultivars and all unregistered cultivars known to the inventor in that it has:

• • 1. Heavily glaucous, upright, stiff, strap-like, flattened, blue-green foliage without twisting;
  • 2. Compact habit, drought tolerant, and deer resistant, medium-sized clumps;
  • 3. Numerous, tightly-clustered, reddish-purple flowers forming dense globose umbel;
  • 4. Strong stems hold flowers heads upright through flowering and seed production.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color.

DETAILED BOTANICAL DESCRIPTION

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.
