Tiarella Lehigh Ground Cover with Maroon Veins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of ornamental ground cover options with distinctive red and green color variations suitable for shaded areas and ecological restoration, as existing varieties either lack the desired color intensity or have limited propagation capabilities.
Innovation Solution
The development of Tiarella cordifolia 'Lehigh' with its compact mounding habit, attractive white flowers, and lobed ovate green leaves with maroon markings, which can be reliably propagated through runners and flower stems, providing a dense and durable ground cover with seasonal color changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing Tiarella varieties are used for ground cover, then propagation is possible, but color intensity and distinctive red-green variations are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific pigment concentrations and color ratios. The 'Lehigh' variety exhibits enhanced anthocyanin content producing intense maroon-red veins and centers, while maintaining green interveinal areas. This selective breeding optimizes the chemical parameters (pigment composition) to achieve the desired color intensity and consistency that distinguishes it from other varieties.
2Area of stationary object
If Tiarella varieties with dense growth habit are selected, then ground cover effectiveness improves, but runner length and propagation speed may be reduced
Solution Approach 1:
The patent applies local quality by creating a plant with differentiated growth characteristics in different regions. The 'Lehigh' variety produces compact, dense clumps with short internodes to maximize ground cover density, while simultaneously developing robust runners with adequate length for effective propagation. This spatial differentiation of growth traits allows the plant to excel at both ground cover formation and asexual reproduction.
3Shape
If Tiarella varieties are bred for ornamental value, then color and flower attractiveness improve, but adaptability to shaded areas and ecological restoration may be compromised
Solution Approach 1:
The patent applies universality by breeding a variety that simultaneously fulfills multiple functions. The 'Lehigh' Tiarella provides ornamental value through its distinctive maroon-red veined foliage and white flowers, while also demonstrating adaptability to shaded environments and suitability for ecological restoration projects. The plant's ability to thrive in partial to full shade, produce abundant runners for ground cover, and maintain aesthetic appeal makes it a multi-functional solution for both ornamental and restorative applications.
