Kniphofia High Roller Hybrid Plant Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Kniphofia cultivars lack unique characteristics such as gracefully arching foliage, rapid growth, dense habit, winter-hardiness, heat tolerance, and resistance to rabbits and deer, as well as distinct flowering patterns.
Innovation Solution
The development of Kniphofia 'High Roller', a hybrid resulting from crossing 'Echo Mango' and 'Sally's Comet', which exhibits gracefully arching gray-green foliage, dense and rapidly growing clumps, and produces numerous deep coral-orange flower buds that open to near-white tepals on tall stems, showcasing improved hardiness and pest resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Kniphofia cultivars are used, then basic flowering function is provided, but they lack unique characteristics such as gracefully arching foliage, rapid growth, dense habit, winter-hardiness, heat tolerance, and pest resistance
Solution Approach 1:
The patent applies parameter changes by creating a hybrid cultivar with modified genetic parameters that result in superior adaptability. The cross between 'Echo Mango' and 'Sally's Comet' produces offspring with enhanced tolerance to adverse conditions including winter-hardiness, heat tolerance, and pest resistance, while maintaining reliable unique characteristics through stable inheritance patterns observed across multiple generations of propagation.
2Length of moving object
If Kniphofia cultivars are bred for taller growth, then flowering height is improved, but foliage architecture and density may be compromised
Solution Approach 1:
The patent applies local quality by differentiating the characteristics of various plant parts. The 'High Roller' cultivar exhibits locally optimized traits where the scape achieves exceptional height (up to 120 cm) while the foliage maintains a distinct gracefully arching form with gray-green coloration. This localized differentiation of traits allows simultaneous optimization of both height and foliage architecture without compromise.
3Productivity
If Kniphofia cultivars are bred for rapid growth and dense habit, then productivity is improved, but hardiness and pest resistance may be reduced
Solution Approach 1:
The patent applies composite materials principle by combining genetic traits from two different parent cultivars to create a composite genotype with superior overall performance. The hybrid 'High Roller' combines the rapid growth and dense habit characteristics from one parent with the hardiness and pest resistance traits from the other parent, resulting in a composite plant that exhibits all five desirable traits simultaneously without trade-offs.

AI summary
A new and distinct cultivar of Red Hot Poker plant named Kniphofia ‘High Roller’ with long, gracefully-arching, strap-like, keeled, glaucous, gray-green foliage and numerous scapes. Habit is densely growing, winter-hardy, tolerant of heat, deer and rabbits. Numerous scapes of deep coral-orange flower buds that open to near white on tall scapes beginning in the first week of summer and repeating into early August. The new plant is useful for landscaping as a specimen, en masse, or as a long-lasting cut flower.
