Hosta Cultivar With Variegated Lanceolate Leaves and Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hosta cultivars lack the unique combination of small-sized, lanceolate leaves with yellowish-chartreuse centers and dark green margins, arching and moderately wavy edges, reddish petiole spotting, and compact mounded habit, making them less suitable for specific garden applications.
Innovation Solution
A new Hosta cultivar, 'Time's Up', featuring these distinct traits, is developed through asexual propagation, providing improved garden performance as edging, border, container, specimen, or mass planting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Hosta cultivars are used, then general foliage traits are available, but the unique combination of small-sized lanceolate leaves with yellowish-chartreuse centers and dark green margins, arching wavy edges, reddish petiole spotting, and compact mounded habit is lacking
Solution Approach 1:
The patent applies local quality by creating distinct visual zones within the leaf structure: yellowish-chartreuse centers contrast with dark green margins, and the petioles feature reddish spotting. This differentiation of local areas within the plant structure provides enhanced aesthetic versatility for garden applications while maintaining a coherent overall plant form.
Solution Approach 2:
The patent employs asymmetry in the leaf morphology with lanceolate shapes, arched forms, and moderately wavy margins that create visual interest and naturalistic appearance. The asymmetric characteristics of the foliage contribute to the plant's adaptability in various garden settings while avoiding uniformity.
2Shape
If Hosta cultivars with similar variegation are used, then some foliage traits are achieved, but the specific combination of small-sized lanceolate leaves with arching and moderately wavy margins is not obtained
Solution Approach 1:
The patent applies segmentation by dividing the leaf blade into distinct functional and aesthetic zones: the yellowish-chartreuse center area contrasts with the dark green margin band. This segmentation of the leaf structure creates the desired shape characteristics while maintaining adequate foliage density through the compact mounded growth habit.
Solution Approach 2:
The patent utilizes curvature in the arched leaf forms and moderately wavy margins to achieve the desired shape characteristics. The arched petioles and leaves create a mounded silhouette, while the wavy margins add textural complexity without reducing foliage density.
3Length of moving object
If Hosta cultivars are used for edging or border applications, then some compact habits are available, but the specific combination of small-sized leaves with lanceolate shape and acute apices is lacking
Solution Approach 1:
The patent applies parameter changes by precisely controlling leaf dimensions to achieve small-sized lanceolate leaves with specific length and width ratios, acute apices, and attenuate bases. These parameter specifications ensure the plant's reliability for edging and border applications while maintaining the desired aesthetic characteristics.
Solution Approach 2:
The patent creates a cultivar with multi-functional versatility suitable for various garden applications including edging, borders, containers, specimen planting, and mass plantings. The small-sized compact habit with reliable foliage characteristics allows the same cultivar to fulfill multiple garden design functions.
