Hosta Trendsetter Hybrid Leaf Variegation and Flower Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a Hosta cultivar that combines specific leaf traits, such as large cordate leaves with wavy, jagged yellow margins and pale lavender flowers, which are not found in existing cultivars, making it difficult to achieve a unique and desirable garden feature.
Innovation Solution
The development of Hosta 'Trendsetter', a hybrid between 'streaked 'Niagara Falls' and 'Empress Wu', which exhibits large cordate leaves with slightly twisted apices, wavy margins, and pale lavender flowers, providing a distinct appearance and growth habit suitable for edging, borders, or mass 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 common traits are achieved, but unique combination of large cordate leaves with wavy jagged yellow margins and pale lavender flowers cannot be obtained
Solution Approach 1:
The patent combines traits from two different Hosta cultivars ('Niagara Falls' providing variegated margins and wavy leaves, and 'Empress Wu' providing large cordate leaf shape and pale lavender flowers) to create a new hybrid cultivar with a unique combination of characteristics that neither parent possesses alone
Solution Approach 2:
The new cultivar exhibits differentiated local qualities with distinct variegated yellow margins contrasting with the green leaf center, and specific structural features like wavy jagged margins and cordate base that create visual interest in different parts of the leaf
2Shape
If Hosta cultivars with desirable leaf traits are selected, then aesthetic value is improved, but disease resistance and adaptability may be compromised
Solution Approach 1:
The patent selects and combines specific genetic parameters from parent cultivars that optimize both aesthetic traits (leaf shape, margin characteristics, flower color) and physiological traits (disease resistance, adaptability), achieving a balanced phenotype that satisfies multiple criteria simultaneously
3Productivity
If propagation by division is used, then plant multiplication is achieved, but time and space requirements increase
Solution Approach 1:
The patent establishes a tissue culture propagation system that can be prepared in advance, allowing for rapid multiplication of the new cultivar when demand arises, rather than relying solely on slower division methods that require plants to reach sufficient size first

AI summary
A new and distinct Hosta plant named ‘Trendsetter’ of medium-sized, arching, long, ovate, medium-green leaves having wavy, yellow, jagged margins with numerous feathering intermediate colors and a narrowly acute curling apex. The flowers are pale lavender beginning in mid-June. ‘Trendsetter’ is attractive and is useful in the landscape, as a specimen or en masse or as a container plant.
