Abstract
A new and distinct cultivar of ornamental Red Hot Poker, Kniphofia plant named ‘Gold Rush’, with long, gracefully-arching, strap-like, keeled, glaucous, gray-green foliage and numerous scapes beginning in late summer with rebloom under optimal growing conditions. Habit is densely-growing, winter-hardy and tolerant of heat. Numerous scapes with dense flowers of intense bright yellow 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: ‘Gold Rush’.
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 on Sep. 23, 2019. Walters Gardens, Inc. obtained the new plant and all information relating thereto, from the inventor. No plants of Kniphofia ‘Gold Rush’ 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.
The present invention relates to the new and distinct Red Hot Poker, Kniphofia ‘Gold Rush’ 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 cross of ‘Sally's Comet’ (not patented) as the female or seed parent and ‘Echo Mango’ U.S. Plant Pat. No. 21,706 as the male or pollen parent performed on Jul. 9, 2013. The plant passed initial evaluation in the summer of 2015 and was subsequently given the breeder code 13-4-2 prior to naming. Kniphofia ‘Gold Rush’ has been successfully asexually propagated by division method since 2015 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.
Kniphofia ‘Gold Rush’ differs from its parents as well as all other Kniphofia known to the applicant. The most similar known Kniphofia cultivars are: ‘Solar Flare’ U.S. Plant patent application Ser. No. 16/350,525, ‘Percy's Pride’ (not patented), ‘Flashpoint’ U.S. Plant Pat. No. 31,282 and ‘Pineapple Popsicle’ U.S. Plant Pat. No. 22,969. ‘Solar Flare’ is shorter in scape and foliage and the flower is deeper yellowish, and the flowers begin earlier in the summer. ‘Percy's Pride’ is taller with more light-yellow to lime-colored flowers and the flower heads are larger. ‘Flashpoint’ has chartreuse-yellow flower buds that produce flowers of creamy white. ‘Pineapple Popsicle’ is shorter in scape height, foliage height and overall habit and has a lighter yellow flower buds and fewer flowers per inflorescence. ‘Sally's Comet’ has a shorter habit and more greenish flower buds with smaller flower heads. ‘Echo Mango’ has a slightly taller habit and the flowers are more orangish-gold.
Kniphofia ‘Gold Rush’ 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 yellow 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 with rebloom in under optimal growing conditions.
The photographs of Kniphofia ‘Gold Rush’ 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.
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. The new plant, Kniphofia ‘Gold Rush’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of a five-year-old plant in a trial garden of a wholesale perennial nursery in Zeeland, Mich. under full sun with supplemental water and fertilizer as needed.
