Heucherella 'Sunrise Falls' Trailing Cultivar with Vein Splatter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Heucherella cultivar that exhibits a trailing habit, larger and more deeply lobed leaves with red tones in fall, and a unique dark splatter pattern on the veins, differing from existing cultivars like Heucherella ‘Yellowstone Falls’ and Tiarella 42-5.
Innovation Solution
The development of Heucherella ‘Sunrise Falls’, resulting from a controlled cross between Heuchera 217-4 and Tiarella 42-5, which displays a vigorous trailing habit, large deeply lobed leaves that transition from yellow to lime green in spring and summer to red in fall, with a dark splatter pattern on the veins, and excellent vigor, achieved through asexual propagation techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a controlled cross between Heuchera 217-4 and Tiarella 42-5 is performed to create Heucherella 'Sunrise Falls', then the new cultivar exhibits a trailing habit with larger, more deeply lobed leaves and red tones in fall, but the breeding process requires extensive time and resources to achieve the desired unique characteristics
Solution Approach 1:
The patent combines the trailing habit of Tiarella 42-5 with the leaf characteristics of Heuchera 217-4 through controlled crossbreeding, creating a hybrid cultivar that exhibits both the trailing growth pattern and the large, deeply lobed leaves with red fall coloration. This merging of parental traits resolves the technical contradiction by achieving unique adaptability characteristics that neither parent alone possesses.
2Stability of the object's composition
If Heucherella 'Sunrise Falls' is propagated through asexual propagation methods, then consistent characteristics are maintained across progeny, but the propagation process requires specialized tissue culture techniques and facilities
Solution Approach 1:
The patent employs asexual propagation through tissue culture to create exact genetic copies of the parent plant. This copying process ensures that all progeny maintain identical characteristics including the trailing habit, leaf morphology, and fall coloration, thereby resolving the technical contradiction by achieving stable composition through precise replication.
3Ease of manufacture
If Heucherella 'Sunrise Falls' is developed with unique dark splatter pattern on veins and specific leaf color transitions, then visual appeal is enhanced, but the selection and identification of these specific traits during breeding requires detailed evaluation criteria
Solution Approach 1:
The patent specifically selects for and describes the unique color characteristics of Heucherella 'Sunrise Falls', including the dark splatter pattern on veins and the transition from yellow-green to red in fall. These color changes serve as distinctive markers that simplify the detection and identification process, resolving the technical contradiction by making the evaluation of visual appeal traits more straightforward through observable color transformations.
