Hosta Time Traveler Variegation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hosta cultivars lack unique foliage variegation patterns with broad rounded leaves featuring three distinct colors, specifically a chartreuse-yellowish margin, narrow gray green center, and a thin creamy-white marbled line between, which are not reproducibly stable across generations.
Innovation Solution
A new Hosta cultivar, 'Time Traveler', resulting from a whole plant mutation of 'Stitch in Time', exhibits stable and reproducible traits with broad rounded leaves displaying chartreuse-yellowish margins, narrow gray green centers, and a thin creamy-white marbled variegation, distinguishing it from other Hostas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a Hosta cultivar displays unique three-color variegation with chartreuse margin, gray green center, and creamy-white marbled line, then aesthetic appeal is improved, but such variegation patterns are not reproducibly stable across generations
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a mutant plant with altered variegation parameters - specifically the addition of a creamy-white marbled intermediate line between the chartreuse margin and gray green center. This creates a new stable parameter configuration (three distinct colors with specific arrangement) that is reproducible through asexual propagation, resolving the contradiction between uniqueness and stability.
2Ease of manufacture
If Hosta leaves display broad rounded shape with complex three-color variegation, then aesthetic appeal is improved, but the foliage pattern becomes more complex to describe and classify
Solution Approach 1:
The patent applies segmentation by dividing the leaf blade into three distinct zones based on variegation patterns: (1) chartreuse to chartreuse-yellowish margin, (2) narrow gray green center, and (3) creamy-white marbled intermediate line. This segmented description method systematically organizes the complex foliage pattern into manageable, describable components, resolving the contradiction between aesthetic complexity and descriptive complexity.
