Hosta Secret Ambition Variegated Foliage and Flower Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Hosta that exhibits unique characteristics such as broadly spreading foliage, variegated leaf colors, and specific flower traits, which are not met by existing cultivars like Secret Love and Sweet Innocence.
Innovation Solution
The cultivar 'Secret Ambition' is a naturally occurring mutation of Hosta hybrid 'Secret Love' with stable asexual reproduction by division, featuring broadly spreading foliage, green and light green variegated leaves, light violet to white flowers, and strong scapes, differing primarily in leaf coloration from its parent and comparable cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new Hosta cultivar is developed with unique leaf coloration, then the aesthetic value and distinctiveness are improved, but the complexity of achieving stable variegation increases
Solution Approach 1:
The patent achieves stable variegation by selecting for specific chromatic parameters in the leaf coloration. The cultivar exhibits consistent light green to yellow-green margins (approximately 144A-144B) against a darker green center (approximately 137A-137C), with the ratio and distribution of these colors being stable across generations through asexual reproduction.
2Area of stationary object
If the foliage is made to spread broadly, then the visual impact and ground coverage are improved, but the plant requires more space and may compete more aggressively
Solution Approach 1:
The patent creates a plant with locally differentiated foliage properties - the leaves exhibit variegation with light green to yellow-green margins (approximately 144A-144B) contrasting with the darker green center (approximately 137A-137C). This local color differentiation enhances visual impact while the overall moderate spread (about 30 cm) maintains adaptability to various garden spaces.
