Eupatorium Capri Variegation Stability Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Eupatorium fortunei cultivars lack a compact, stable variegation and consistent growth habit, with 'Pink Frost' and 'Frosted Elegance' exhibiting height variations and less stable leaf coloration.
Innovation Solution
A new cultivar, 'Capri', characterized by grey-green leaves with creamy margins, a low upright habit, and excellent vigor, achieved through asexual propagation methods ensuring consistent characteristics across progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional Eupatorium fortunei cultivars like 'Pink Frost' or 'Frosted Elegance' are used, then the plant exhibits variegation and growth, but the height becomes excessive and variegation stability is poor
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a mutant plant with altered growth parameters. The new cultivar 'Capri' exhibits a compact growth habit (2-2.5 feet tall) and stable variegation that differ from the parent plant 'Pink Frost'. This represents a change in the plant's growth parameters achieved through mutation and selective propagation, resolving the contradiction between height control and variegation stability.
2Stability of the object's composition
If asexual propagation is used to maintain consistent characteristics, then trait consistency is improved, but propagation complexity increases
Solution Approach 1:
The patent employs self-service through vegetative propagation methods where the plant reproduces itself asexually. By taking cuttings from the parent plant or micropropagating from tissue culture, the cultivar maintains its unique characteristics without requiring complex genetic manipulation. The plant essentially propagates itself while preserving the desired traits of compact size and stable variegation, balancing trait consistency with manageable propagation complexity.
