Echinacea Sunbird Cultivar Reflexed Ray Florets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Echinacea cultivars lack compact habits and unique 'shuttlecock' inflorescence characteristics, with existing varieties like 'Now Cheesier' having spreading ray florets rather than reflexed ones, which limits their aesthetic and horticultural appeal.
Innovation Solution
A new Echinacea cultivar 'Sunbird' with darker yellow-orange reflexed ray florets, medium habit, strong upright stems, excellent vigor, and good branching, achieved through asexual propagation techniques like division and tissue culture, maintaining consistent characteristics across progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If Echinacea cultivars are bred for spreading ray florets (like 'Now Cheesier'), then the inflorescence covers a larger area, but the compact habit and unique 'shuttlecock' shape are lost
Solution Approach 1:
The patent applies parameter changes by modifying the growth pattern and orientation of ray florets through selective breeding. The ray florets are bred to reflex backward at specific angles (creating the shuttlecock shape) rather than spreading horizontally, fundamentally changing the spatial parameters of inflorescence development while maintaining compact overall dimensions.
2Area of moving object
If Echinacea cultivars are bred for large ray florets, then the floral display is more prominent, but the compact habit is compromised
Solution Approach 1:
The patent applies local quality by concentrating the large ray floret characteristics specifically in the reflexed florets that form the shuttlecock shape, while maintaining compact overall plant architecture. The large florets are localized to the terminal inflorescence structure rather than being distributed throughout the plant, allowing prominent floral display within a compact form.
3Adaptability or versatility
If Echinacea cultivars are propagated by sexual reproduction, then genetic diversity is increased, but the consistency of unique characteristics like reflexed ray florets is reduced
Solution Approach 1:
The patent applies copying by using asexual propagation methods (tissue culture and division) to create exact genetic copies of the parent plant with the unique shuttlecock characteristics. This ensures that the reflexed ray floret trait and compact habit are consistently reproduced in all progeny, maintaining characteristic consistency while allowing for future genetic diversity through selective breeding programs.
