Hosta ECLIPSE Cultivar Foliage Color and Pest Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hosta cultivars lack unique foliage color and resistance to scorching and slug activity, with limited tolerance to environmental variations.
Innovation Solution
The development of the Hosta cultivar 'ECLIPSE', characterized by medium blue-green leaves with golden-yellow edges, undulate leaf edges, and heavy substance, which are resistant to scorching and slugs, and suitable for partial to full shade with moist well-draining soils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Hosta cultivars are used, then they provide basic foliage, but they lack unique foliage color and are susceptible to scorching and slug activity
Solution Approach 1:
The patent applies parameter changes by developing a Hosta cultivar with modified physical and physiological characteristics. The 'ECLIPSE' cultivar exhibits changed parameters including heavy leaf substance (increased density/mass), undulate leaf edges (changed surface geometry), and specific blue-green coloration with golden-yellow margins (changed optical properties). These parameter changes collectively provide resistance to scorching and slug activity while maintaining adaptability to various garden conditions.
2Object-affected harmful factors
If Hosta cultivars with heavy substance foliage are developed, then resistance to slug activity improves, but breeding complexity increases
Solution Approach 1:
The patent applies self-service by allowing the Hosta plant to naturally develop resistance to slug activity through its inherent heavy substance foliage characteristic. The cultivar 'ECLIPSE' possesses intrinsic defenses (heavy leaves, undulate edges) that protect against slugs without requiring external chemical or mechanical interventions. This self-service approach simplifies the overall system by eliminating the need for additional pest control mechanisms.
3Adaptability or versatility
If Hosta cultivars are bred for unique characteristics, then foliage color and resistance improve, but stability and uniformity of traits may compromise
Solution Approach 1:
The patent applies copying by propagating the 'ECLIPSE' cultivar through asexual reproduction methods (division of rhizomes or cuttings) that create genetically identical copies of the parent plant. This ensures that the unique foliage characteristics (blue-green color with golden-yellow margins, undulate edges, heavy substance) are uniformly replicated across multiple plants, maintaining both the uniqueness of the trait and the stability of its expression throughout the cultivar population.

AI summary
A new cultivar of Hosta named ‘ECLIPSE’ that is characterized by upright, clumping habit, early summer white flowers, giant medium blue-green leaves with golden-yellow edges that brighten as the season progresses. In combination these traits set ‘ECLIPSE’ apart from all other existing varieties of Hosta known to the inventor.
