Sedum Cherry Truffle Upright Growth and Crown Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Sedum cultivars lack a medium-height, upright accent plant with distinctive purple-black leaves and pink flowers that can form multiple crowns quickly, while maintaining strong stems and a unique two-toned leaf coloration.
Innovation Solution
The development of a new Sedum cultivar, 'Cherry Truffle', resulting from a cross between an unnamed proprietary Sedum telephium seedling and Sedum telephium PP5, characterized by its larger size, broader habit, purple-black leaves, pink flowers, and strongly upright stems, achieved through asexual propagation techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If Sedum cultivars are developed to be larger with broader habit, then the plant size and crown formation speed improve, but the stem strength and upright stability may deteriorate
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with specific genetic characteristics that alter the relationship between plant size and stem strength. The 'Cherry Truffle' cultivar achieves larger volume (54 cm wide vs typical Sedum) while maintaining strong upright stems through selective breeding, changing the physical parameters of the plant to simultaneously improve both size and structural integrity.
2Productivity
If Sedum cultivars are developed to form multiple crowns quickly, then the productivity and landscape establishment speed improve, but the plant may become less stable and more prone to falling over
Solution Approach 1:
The cultivar 'Cherry Truffle' utilizes parameter changes through genetic selection to achieve rapid crown formation (forming multiple crowns quickly as stated in the patent) while maintaining structural stability. The plant's genetic parameters are optimized to produce strong stems that support the broader habit and multiple crowns without compromising stability.
3Shape
If Sedum cultivars are developed with distinctive leaf colors and flower characteristics, then the visual distinctiveness and aesthetic value improve, but the plant may become more sensitive to environmental variations
Solution Approach 1:
The patent applies parameter changes by selecting for specific phenotypic parameters (purple-black leaves, pink flowers, two-toned spring foliage) while maintaining genetic stability for environmental adaptability. The cultivar exhibits these distinctive visual characteristics across varying environmental conditions, with the genotype remaining stable even as phenotype may vary slightly with environment.
4Stability of the object's composition
If Sedum cultivars are propagated asexually to maintain consistent characteristics, then the genetic uniformity and trait consistency improve, but the genetic diversity and adaptability to new conditions decrease
Solution Approach 1:
The patent utilizes copying through asexual propagation methods (division and tissue culture) to reproduce the 'Cherry Truffle' cultivar. This copying process creates genetically identical copies that maintain the distinctive characteristics (purple-black leaves, pink flowers, upright habit) consistently across multiple propagations, ensuring trait fidelity while allowing widespread distribution of the cultivar.
