Penstemon Cha Cha Pink Compact Growth and Dense Flower Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Penstemon cultivars lack a compact, upright, medium-sized variety with long flowering time, dense rose pink flower clusters, and attractive foliage, which are key characteristics for a visually appealing and sustainable garden feature.
Innovation Solution
A new Penstemon cultivar, 'Cha Cha Pink', is developed through controlled breeding, exhibiting compact growth, medium-sized rose pink flowers in dense clusters, long bloom time, and attractive deep green foliage, distinguished by its compact, upright habit and excellent vigor, achieved through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Penstemon cultivars are used, then they have larger flowers and more spreading growth habit, but they lack compact size, long flowering time, and dense flower clusters
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that produce compact growth habits while simultaneously achieving dense flower clusters. The cultivar 'Cha Cha Pink' exhibits altered growth parameters including reduced internode length and increased branching density, which creates the compact form while maintaining high flower cluster density through controlled asexual propagation that preserves these optimized parameters.
2Duration of action of moving object
If existing Penstemon cultivars are used, then they have shorter flowering periods, but the new cultivar achieves long bloom time from June to October
Solution Approach 1:
The patent employs copying through asexual propagation methods including cuttings and micropropagation to replicate the parent plant's genetic material and physiological traits. This copying process ensures that the long flowering duration trait (June to October bloom period) is reliably transmitted to progeny without genetic variation, maintaining trait consistency across multiple generations of propagated plants.
3Device complexity
If existing Penstemon cultivars are used, then they have larger leaves and more open growth, but the new cultivar has narrower leaves and tighter clusters
Solution Approach 1:
The patent applies segmentation by increasing the number of branching points and dividing the growth structure into more segments. The cultivar 'Cha Cha Pink' exhibits multiple crowns from the base and extensive lateral branching, which segments the overall plant structure into numerous smaller units. This segmentation creates the appearance of complexity in the branching structure while reducing individual leaf size and creating tighter, more compact flower clusters through the increased division of growth space.
