Echinacea Drop352 Cultivar Compact Growth Strong Stems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Echinacea cultivars with unique and attractive ray floret coloration, compact growth, and improved branching and flowering characteristics that are not met by existing varieties like 'Meringue' and 'Meteor Yellow'.
Innovation Solution
A new Echinacea purpurea cultivar 'Drop352' was developed through planned breeding, characterized by a broadly upright, moderately vigorous, and freely branching habit with orange-yellow to yellow-green ray florets and bright yellow disc florets, exhibiting stable traits through asexual reproduction by in vitro meristem culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If Echinacea plants are bred for compact growth habit, then plant height and spread are reduced, but flowering stem strength and inflorescence support may be compromised
Solution Approach 1:
The patent applies local quality by differentiating between overall plant compactness and localized stem strength. The 'Drop352' cultivar exhibits compact growth habit (31.5 cm height to foliar plane) while simultaneously developing strong, rigid flowering stems that can support large double-type inflorescences. This is achieved through selective breeding that targets specific structural characteristics independently of overall plant size.
2Productivity
If Echinacea plants are bred for freely branching habit, then number of inflorescences increases, but plant structure may become less compact
Solution Approach 1:
The patent resolves this contradiction by organizing the freely branching habit in a three-dimensional compact structure. The 'Drop352' cultivar produces numerous lateral branches (about seven per plant) that are arranged densely and upright, creating a full, bushy appearance within a compact 31.5 cm height. This dimensional arrangement allows high flowering frequency without sacrificing compactness.
3Shape
If Echinacea plants produce large double-type inflorescences, then floral attractiveness increases, but plant vigor and continuous flowering may be reduced
Solution Approach 1:
The patent applies segmentation by distributing the plant's reproductive effort across multiple inflorescences rather than concentrating resources in single large flowers. The 'Drop352' cultivar produces numerous inflorescences (about 14 per plant during flowering season) with moderate-sized double-type flowers, allowing continuous flowering throughout the season while maintaining overall plant vigor and productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new cultivar 'Drop352' demonstrates improved flowering performance, tolerance to environmental variations, and good garden performance, differing from 'Meringue' and 'Meteor Yellow' in stem length, inflorescence size, and flowering frequency, while maintaining stability across generations.
Implementation Method 1
Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Zuidwolde, The Netherlands since June, 2016 has shown that the unique features of this new Echinacea plant are stable and reproduced true to type in successive generations.
