Ruby Frost Coreopsis Compact Hybrid with White-Edged Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Coreopsis varieties lack compact forms with distinct, consistently white-edged red-purple flowers and dense mounding habits, making them less desirable for landscaping and horticultural applications.
Innovation Solution
Development of a new Coreopsis hybrid, 'Ruby Frost', resulting from a controlled cross between Coreopsis 'Rum Punch' and Coreopsis lanceolata 'Sonnenkind', characterized by large daisy-type flowers with white-edged red-purple petals, compact growth, and grass green foliage, propagated asexually to ensure trait consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Coreopsis varieties are used, then they have established flower colors and forms, but they lack compact growth habits and consistent white-edged red-purple flower characteristics
Solution Approach 1:
The patent combines desirable traits from two different Coreopsis varieties through controlled hybridization: the compact growth habit and white-edged red-purple flowers from one parent and the overall plant vigor from the other, creating a new cultivar that exhibits both compact form and consistent flowering characteristics
Solution Approach 2:
The invention changes the genetic parameters of the Coreopsis plant through selective breeding, specifically modifying growth habit parameters to achieve compactness while maintaining flower size and color consistency across generations through asexual propagation
2Reliability
If asexual propagation is used to ensure trait consistency, then the cultivar maintains uniform characteristics, but the propagation process requires specialized techniques and facilities
Solution Approach 1:
The patent employs asexual propagation methods including tissue culture and cutting propagation to create genetically identical copies of the parent plant, ensuring that the compact growth habit and white-edged red-purple flower characteristics are consistently reproduced across multiple generations without genetic variation
