Echinacea Fatal Attraction Compact Growth and Color Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Echinacea purpurea that exhibits a compact and upright growth habit, with freely flowering inflorescences and specific color characteristics, as existing cultivars like Rubinstern lack the desired compactness and distinct peduncle and ray floret colors.
Innovation Solution
The cultivar 'Fatal Attraction' is developed through open-pollination of an unnamed Echinacea purpurea selection, showcasing a compact, upright plant habit with dark purple peduncles and darker red-purple ray florets, distinguishing it from other Echinacea cultivars such as Rubinstern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Echinacea cultivars like Rubinstern are used, then they have vigorous growth and flowering, but they lack compactness and have less uniform growth habit
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic traits through controlled open-pollination breeding. The cultivar 'Fatal Attraction' was developed by changing the growth habit parameter from the vigorous but spreading form of parent selections to a compact, upright form while maintaining flowering productivity. This is achieved through selective breeding that modifies plant architecture parameters without sacrificing reproductive output.
2Ease of manufacture
If existing Echinacea cultivars are used, then they have flowering capability, but they lack distinct peduncle and ray floret coloration
Solution Approach 1:
The patent applies local quality by enhancing specific localized traits of the plant rather than overall characteristics. The cultivar 'Fatal Attraction' exhibits distinct dark purple peduncles and darker red-purple ray florets, creating visually differentiated local features that stand out against the foliage and background. This selective enhancement of specific plant parts (peduncles and ray florets) with distinctive coloration provides aesthetic value while maintaining overall plant health and flowering reliability.
3Adaptability or versatility
If open-pollination breeding is used to create new cultivars, then genetic diversity is achieved, but trait stability across generations may be compromised
Solution Approach 1:
The patent applies feedback through iterative selection and evaluation across multiple generations. The breeder conducted open-pollination, then systematically evaluated progeny for desired traits (compactness, upright habit, flowering frequency, coloration), selecting the best performers for further propagation. This feedback loop of selection, propagation, and re-evaluation ensured that the cultivar 'Fatal Attraction' stabilized its unique combination of traits while maintaining the genetic diversity benefits of open-pollination breeding.

AI summary
A new and distinct cultivar of Echinacea plant named ‘Fatal Attraction’, characterized by its compact and upright plant habit; moderately vigorous growth habit; freely flowering habit; large single inflorescences with red purple-colored ray florets; and strong dark purple-colored peduncles that hold the inflorescences above the foliar plane.
