Kniphofia Jackpot Hybrid Plant Heat Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Kniphofia cultivars lack persistence in landscapes, adequate heat tolerance, and resistance to rabbits and deer, with limited unique characteristics such as foliage and flower color, and inconsistent flowering periods.
Innovation Solution
The development of Kniphofia 'Jackpot', a hybrid resulting from 'Echo Rojo' and 'Papaya Popsicle', exhibiting gracefully arching gray-green foliage, rapid growth, dense habit, and vibrant reddish-orange flowers, which is winter-hardy, heat-tolerant, and resistant to rabbits and deer, with prolonged flowering periods from early summer to early October.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Kniphofia cultivars are used, then they have basic ornamental value, but they lack persistence in landscapes and have poor heat tolerance
Solution Approach 1:
The patent combines multiple desirable traits from different parent cultivars through hybridization. The hybrid Kniphofia merges the persistence and heat tolerance characteristics with enhanced ornamental features, creating a single cultivar that simultaneously achieves landscape persistence, heat tolerance, and improved foliage/flower characteristics that neither parent possessed alone.
Solution Approach 2:
The hybrid cultivar represents a composite genetic material combining traits from both parent cultivars. Through controlled hybridization, the patent creates a composite plant genotype that integrates persistence, heat tolerance, and unique foliage characteristics (gray-green color, arching habit) and flower traits (reddish-orange color, prolonged blooming) into a single stable variety.
2Ease of manufacture
If conventional Kniphofia cultivars are used, then they have standard foliage and flower colors, but they lack unique characteristics such as gray-green foliage and vivid reddish-orange flowers
Solution Approach 1:
The patent emphasizes specific local qualities in the hybrid cultivar: gray-green foliage color, arching growth habit, and vivid reddish-orange flower coloration. These localized distinctive traits differentiate the hybrid from conventional cultivars and are maintained through stable propagation methods, providing unique ornamental value while ensuring reliability.
3Duration of action of moving object
If conventional Kniphofia cultivars are used, then they have limited flowering periods, but they fail to provide prolonged flowering from early summer to early October
Solution Approach 1:
The hybrid cultivar achieves continuous flowering from early summer through early October by producing successive flower spikes over an extended period. This continuity of ornamental action is accomplished through the plant's ability to repeatedly bloom, maintaining productivity throughout the growing season rather than having a single brief flowering event.

AI summary
A new and distinct cultivar of Red Hot Poker plant named Kniphofia ‘Jackpot’ with long, gracefully-arching, strap-like, keeled, glaucous, gray-green foliage and numerous scapes beginning in early summer and repeating though early fall. Habit is densely growing, winter-hardy, tolerant of heat, deer and rabbits. Numerous scapes of vivid reddish-orange flowers on tall scapes beginning in early summer and repeating into early October. The new plant is useful for landscaping as a specimen, en masse, or as a long-lasting cut flower.
