Dixie Sun Echinacea Compact Habit Prolonged Bloom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echinacea cultivars lack a compact habit with profuse inflorescences and extended bloom time, and there is a need for a cultivar with distinct yellow ray florets that maintain color intensity and exhibit excellent vigor and rebloom capabilities.
Innovation Solution
A new Echinacea cultivar 'Dixie Sun' is developed, characterized by bright orange-yellow young ray florets maturing to yellow, an upright compact habit, numerous strong stems, and prolonged blooming, achieved through proprietary interspecific hybrids of Echinacea paradoxa, Echinacea purpurea, and Echinacea tennesseensis, reproduced via asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Echinacea cultivars are used, then they have basic bloom characteristics, but they lack compact habit with profuse inflorescences and extended bloom time
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control habit compactness, inflorescence number, and bloom duration. The cultivar 'Dixie Sun' exhibits a compact habit (23 cm wide, 53 cm tall) with multiple flowering stems (1-3) that each produce multiple inflorescences, and maintains prolonged blooming from July through October, representing optimized parameter values for productivity while maintaining desirable shape characteristics.
2Reliability
If existing Echinacea cultivars are used, then they have standard color patterns, but they lack distinct yellow ray florets that maintain color intensity
Solution Approach 1:
The patent applies local quality by focusing on the specific color characteristics of the ray florets. The cultivar 'Dixie Sun' displays distinctive bright orange-yellow young ray florets that mature to yellow (Yellow Orange 17A to Yellow Orange 16B on topside, Yellow Orange 19C to Green Yellow 1C on bottom side), maintaining color intensity throughout the bloom period rather than fading to cream or other colors. This localized color property differentiation resolves the contradiction between color intensity reliability and color pattern distinctiveness.
3Productivity
If existing Echinacea cultivars are used, then they have moderate vigor, but they lack excellent vigor and rebloom capabilities
Solution Approach 1:
The patent applies continuity of useful action through the cultivar's extended bloom period and rebloom capability. 'Dixie Sun' produces inflorescences continuously from July through October, with each inflorescence lasting about two weeks and the plant exhibiting excellent rebloom, meaning it continues to produce new flowering stems and inflorescences throughout the season. This continuous flowering activity, supported by excellent vigor and numerous strong stems, resolves the contradiction between productivity and strength by maintaining sustained physiological function.
