BACKGROUND AND ORIGIN OF THE PLANTThe present invention relates to the new and distinct Red Hot Poker, Kniphofia ‘Poker Face’ hybridized under the direction of the inventor at a wholesale perennial nursery in Zeeland, Mich., USA. The new plant was the result of a single seedling selection from a cross of ‘Echo Rojo’ U.S. Plant Pat. No. 22,791 as the female parent as the female parent and ‘Papaya Popsicle’ U.S. Plant Pat. No. 22,915 as the male parent as the male parent in 2012. The plant passed initial evaluation in the summer of 2014 and was subsequently given the breeder code KNIF-12-5. Kniphofia ‘Poker Face’ has been successfully asexually propagated by garden rhizome division method since 2014 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 multiple generations.
No plants of Kniphofia ‘Poker Face’ have been sold, in this country or anywhere in the world, with this name or any other name, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application except that which was disclosed within one year of the filing of this application and was either derived directly or indirectly from the inventor.
SUMMARY OF THE PLANTKniphofia ‘Poker Face’ differs from its parents as well as all other Kniphofia known to the applicant. The most similar known Kniphofia cultivars are the female parent ‘Echo Rojo’, ‘Mango Popsicle’ U.S. Plant Pat. No. 22,968, the male parent ‘Papaya Popsicle’ and ‘Poco Orange’ U.S. Plant patent application Ser. No. 14/545,806. ‘Echo Rojo’ is slightly taller in scape height but more reddish in flower color and the new plant is more persistent in the Michigan landscape. ‘Mango Popsicle’ is shorter in scape and foliage height with more yellow-orange flower color. ‘Papaya Popsicle’ is shorter in scape and foliage height with deeper orange flower color. ‘Poco Orange’ is smaller in scape height, foliage height and overall habit and has a lighter orange flower color.
Kniphofia ‘Poker Face’ 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 and low moisture tolerant, rabbit and deer tolerant, large-sized clumps.
- 3. Numerous spikes of medium orange flowers on tall stems lightening in maturity;
- 4. Flowering beginning the first week of summer and repeating into early October in Michigan.
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.
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 ‘Poker Face’, 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 four-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.
