Hosta ‘Leaving Me Breathless’ Variegation With Stable Asexual Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hosta cultivars lack the unique combination of medium-sized, broadly ovate leaves with bluish-green margins and pale-yellow to creamy-white centers, slightly wavy edges, and arching scapes bearing pale purple flowers with variegated floral bracts that mimic leaf variegation, starting in mid-July, which are not found in currently registered cultivars.
Innovation Solution
Development of the Hosta 'Leaving Me Breathless' cultivar, characterized by medium-sized, broadly ovate leaves with bluish-green margins and pale-yellow to creamy-white centers, slightly wavy edges, and arching scapes bearing pale purple flowers with variegated floral bracts that subtend each bloom, beginning in mid-July.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Hosta cultivars are used, then established varieties with blue-green leaf blades are available, but none possess the unique combination of medium-sized broadly ovate leaves with bluish-green margins, pale-yellow to creamy-white centers, slightly wavy edges, and arching scapes with pale purple flowers and variegated floral bracts
Solution Approach 1:
The patent applies local quality by creating distinct regional variations within the leaf structure - bluish-green margins contrasting with pale-yellow to creamy-white centers, and variegated floral bracts mimicking leaf variegation. This localized differentiation of colors and patterns across different parts of the plant achieves the unique combination of traits that distinguishes this cultivar from existing Hostas.
2Stability of the object's composition
If Hosta cultivars are propagated asexually, then traits are retained through division and tissue culture, but maintaining stability across successive generations requires careful propagation methods
Solution Approach 1:
The patent employs self-service through asexual propagation methods where the plant reproduces itself through division and tissue culture, automatically retaining all genetic traits without requiring external intervention for genetic preservation. This ensures trait stability while allowing multiple propagation pathways.
Solution Approach 2:
The patent uses copying through asexual propagation where identical genetic copies are created through division and tissue culture methods. This produces multiple plants with exactly the same traits as the parent plant, ensuring stability across generations while enabling efficient multiplication of the cultivar.

AI summary
A new and distinct Hosta plant named ‘Leaving Me Breathless’ produces medium-sized low mounds. The foliage is in basal rosettes, broadly ovate, leaves with long narrowly acute apices, cordate bases and slightly wavy margins. The leaves are variegated having bluish-green margins and pale-yellow to creamy white centers with intermediate color separation between the margin and center of variably large segments of several shades of chartreuse. The medium-sized leaves have a glaucous matte top and bottom. The broadly campanulate flowers are pale purple with white edges appearing beginning in mid-July. Each flower is attractively subtended by a floral bract that mimics the leaf variegation making the scape showy for long periods. ‘Leaving Me Breathless’ is useful in the landscape, as a container plant, a specimen or en masse.
