Hosta Cultivar With Feathered Variegation and Arching Mounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hosta cultivars lack a unique combination of large, broadly ovate leaves with bluish-green margins and olive-green centers, arching habit, and pale lavender flowers densely arranged on scapes, making them less distinctive in garden applications.
Innovation Solution
Development of a new Hosta cultivar, 'Avant Garde', with large, broadly ovate leaves featuring bluish-green margins and olive-green centers, arching habit, and pale lavender flowers, suitable for edging, borders, containers, or en masse planting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Hosta cultivars with green leaf blades and variegated margins are used, then they provide ornamental value, but they lack a unique combination of large broadly ovate leaves with bluish-green margins and olive-green centers
Solution Approach 1:
The patent applies local quality by creating distinct color zones within the leaf blade - bluish-green margins contrasting with olive-green centers, and feathering patterns with intermediate colors. This regional differentiation of leaf properties enhances ornamental value while achieving uniqueness through localized color variations rather than uniform changes across the entire plant.
2Ease of operation
If Hosta cultivars with smaller or less distinctive foliage are used, then they may be easier to maintain, but they lack large mounded habit useful for edging, borders, containers, or specimen planting
Solution Approach 1:
The patent describes a dynamic growth habit where leaves arch outward and upward to form a large mound shape. This arching configuration allows the plant to achieve substantial size and visual impact while maintaining a low-center-of-gravity structure that is stable and easier to maintain compared to upright, top-heavy forms. The dynamic arching habit enables the plant to fill space effectively for edging, borders, and container applications.
3Device complexity
If Hosta cultivars with less densely arranged flowers are used, then they may have simpler flower structures, but they lack pale lavender flowers densely arranged on scapes with first flowers opening just above foliage
Solution Approach 1:
The patent combines multiple floral characteristics - pale lavender coloration, dense arrangement of flowers along the scape, and positioning of the first flowers just above the foliage level. This merging of traits creates a visually impactful flowering display where the dense clustering of simple pale lavender flowers produces complexity in overall appearance while maintaining relative simplicity in individual flower structure.

AI summary
A new and distinct Hosta plant named ‘Avant Garde’ of large arching mounds of broadly ovate leaves having wide bluish-green margins and khaki with olive-green centers. The variegation is also attractively displayed with numerous featherings of intermediate colors between the center the leaf margins. The flowers are very pale lavender held just above the foliage beginning in late June for about three weeks. ‘Avant Garde’ has excellent large mounded habit and is useful in the landscape, as a specimen, or en masse.
