USPP32263P2 - Kniphofia plant named ‘Joker's Wild’ - Google Patents

Abstract

A new and distinct cultivar of ornamental Red Hot Poker, Kniphofia plant named ‘Joker's Wild’, with long, gracefully-arching, strap-like, keeled, glaucous, gray-green foliage and numerous scapes beginning in late summer. Habit is densely-growing, winter-hardy and tolerant of heat. Numerous scapes with dense flowers of bright deep orange buds that retain their color when flowers open. The new plant is useful for landscaping as a specimen, en masse, or as a long-lasting cut flower.

Description

Botanical classification: Kniphofia hybrid.

Variety denomination: ‘Joker's Wild’.

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, was made by Walters Gardens, Inc. on Feb. 1, 2019 on their website. Subsequently, on May 29, 2019, the claimed plant was displayed with a photograph and brief sales promotion on the “Walters Gardens 19-20 Catalog.” Walters Gardens, Inc. sold the first plants of ‘Joker's Wild’ on Mar. 23, 2019. Walters Gardens, Inc. obtained the new plant and all information relating thereto, from the inventor. No plants of Kniphofia ‘Joker's Wild’ 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 any such sale or disclosure of the new plant 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 Red Hot Poker, Kniphofia ‘Joker's Wild’ developed under the direction of the inventor at a wholesale perennial nursery in Zeeland, Mich., USA in the summer of 2013. The new plant was the result of a single seedling selection from a self-pollination of ‘Alcazar’ (not patented) on Jul. 28, 2014. The plant passed initial evaluation in the summer of 2016 and was subsequently given the breeder code 14-9-1 prior to naming. Kniphofia ‘Joker's Wild’ has been successfully asexually propagated by division method since 2016 at the same wholesale perennial nursery in Zeeland, Mich. and subsequently by shoot tip tissue culture, and both methods have been found to be stable and produce identical plants that maintain the unique characteristics of the original plant through successive generations.

SUMMARY OF THE PLANT

Kniphofia ‘Joker's Wild’ differs from its parent as well as all other Kniphofia known to the applicant. The most similar known Kniphofia cultivars are: ‘Backdraft’ U.S. Plant Pat. No. 31,424, ‘Ember Glow’ U.S. Plant Pat. No. 23,000, ‘Jackpot’ U.S. Plant Pat. No. 31,283, ‘High Roller’ U.S. Plant patent application Ser. No. 16/350,857, ‘Poker Face’ U.S. Plant Pat. No. 31,346, ‘Mango Popsicle’ and ‘Orange Blaze’ U.S. Plant Pat. No. 31,545. ‘Backdraft’ is shorter in scape and foliage and the flower is reddish-orange opening to peachy-yellow, and the flowering season is slightly longer. ‘Ember Glow’ is about half the height and the flowers are a lighter orange opening to yellow and the flower heads are smaller. ‘Jackpot’ is shorter in habit and the flowers open to yellow with more flowers per stem. ‘High Roller’ is slightly shorter in habit and the flowers begin a deeper reddish orange and lighten to near white. ‘Poker Face’ is slightly shorter in habit and the flowers are a lighter orange. ‘Mango Popsicle’ is shorter in scape and foliage height, the flowers are lighter orange with fewer flowers per inflorescence. ‘Orange Blaze’ has a much shorter habit, the flowers are lighter orange and there are fewer flowers per stem. ‘Alcazar’ has buds that begin more reddish-orange then lighten to orange and open yellowish on significantly taller plants.

Kniphofia ‘Joker's Wild’ differs from these above cultivars and all cultivars known to the inventor in that it has:

• • 1. Gracefully arching, strap-like, keeled, gray-green foliage.
  • 2. Rapidly growing, dense habit, winter-hardy, heat tolerant, rabbit and deer tolerant, moderate-sized clumps.
  • 3. Numerous spikes of bright deep orange buds on medium height stems that retain their color when open on medium height stems;
  • 4. Flowering beginning late summer for three weeks in Michigan.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of Kniphofia ‘Joker's Wild’ 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.
