Echinacea Eccentric Cultivar Breeding for Stem Strength and Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new cultivars of Echinacea purpurea that exhibit unique and attractive flower form and coloration, as existing cultivars may lack distinctiveness in stem strength, flowering density, and inflorescence color intensity.
Innovation Solution
The development of the 'Eccentric' cultivar, which features strong upright stems, numerous flowering stems, and anemone-type inflorescences with red-purple to orange-red coloration, achieved through a breeding program that selected a unique seedling with stable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Echinacea cultivars are used, then basic flowering is achieved, but stem strength and upright growth are insufficient
Solution Approach 1:
The breeding program selectively changed genetic parameters to produce stems with superior strength and upright growth habits. The 'Eccentric' cultivar exhibits markedly stronger, more rigid stems compared to parent plants, representing a parameter change in stem mechanical properties through selective breeding.
2Illumination intensity
If standard inflorescence types are produced, then basic flowering is achieved, but color intensity and uniqueness are insufficient
Solution Approach 1:
The breeding program specifically targeted color intensity and hue, producing the distinctive red-purple to orange-red coloration of 'Eccentric'. This represents a color change parameter optimization, achieving superior color saturation and uniqueness compared to conventional cultivars.
Solution Approach 2:
The 'Eccentric' cultivar displays anemone-type semi-double inflorescences with asymmetric petal arrangements and enlarged disk floret petals, creating a unique structural complexity that distinguishes it from standard single-flowered Echinacea varieties.
3Quantity of substance
If few flowering stems are produced, then plant simplicity is maintained, but flowering density and景观 value are insufficient
Solution Approach 1:
The plant architecture of 'Eccentric' is segmented into multiple independent flowering stems, each capable of producing full inflorescences. This segmentation increases the total flowering output and extends the blooming period, as different stems may flower at slightly different times.
4Duration of action of moving object
If brief flowering periods are exhibited, then seasonal adaptation is simplified, but ornamental value and landscape use are reduced
Solution Approach 1:
The 'Eccentric' cultivar achieves continuous flowering from early July to late September through coordinated development of multiple flowering stems with staggered blooming times. This continuity of ornamental action extends the useful flowering period significantly compared to single-stem varieties.

AI summary
A new cultivar of hybrid Echinacea, ‘Eccentric’, characterized by its anemone-type inflorescences (semi-double) with ray florets and disk florets that are initially red-purple in color and mature to orange-red; disk florets exhibit an enlarged petal and its numerous flowering stems that are strong and held upright, its floriferous habit, and it compact and short plant habit.
