Penstemon Red Riding Hood Compact Growth and Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Penstemon cultivars lack compact and strongly flowering varieties with intense red flower colors, which limits their garden performance and aesthetic appeal.
Innovation Solution
A new cultivar, 'Red Riding Hood', resulting from a planned breeding program, characterized by a compact and upright growth habit, strong flowering stems, and intense red-colored flowers, achieved through cross-pollination and asexual reproduction by vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Penstemon cultivars are used, then they have larger plant size, but they lack compactness and have weaker flowering stems
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in both compact growth habit and strong flowering stems. The cultivar 'Red Riding Hood' exhibits altered growth parameters including reduced internode length and increased stem thickness compared to parent selections, achieving both compactness and structural strength simultaneously.
2Quantity of substance
If traditional Penstemon cultivars are used, then they have sufficient flower production, but they lack intense red flower color
Solution Approach 1:
The patent applies local quality by concentrating intense red pigmentation specifically in the flower petals while maintaining overall plant vigor and flower production. The cultivar exhibits enhanced anthocyanin production localized to the floral tissues, creating vivid red coloration without compromising the quantity of flowers produced.
3Volume of moving object
If Penstemon cultivars are bred for compactness, then plant size is reduced, but flowering intensity may be compromised
Solution Approach 1:
The patent applies dynamics by creating a cultivar that dynamically balances compact growth with vigorous flowering. The plant exhibits optimized resource allocation where reduced overall plant volume does not constrain floral development, instead channeling energy efficiently to produce intense flowering displays within a compact form factor.
