Veronica 'Very Van Gogh' Plant Segmented Scape Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spiked speedwell cultivars lack a combination of traits such as tall, well-branched scapes with continuous heavy flower show and rosy purple flowers, which are self-cleaning and persist well as cut flowers, making 'Very Van Gogh' distinct from other varieties.
Innovation Solution
The new cultivar 'Very Van Gogh' is a hybrid of Veronica longifolia×Veronica spicata, characterized by its taller stature, more branched scapes, and more purple-pigmented flowers compared to other cultivars, with unique foliage and flower characteristics that set it apart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Veronica cultivars are bred for tall stature and heavy flower show, then flowering productivity is improved, but plant complexity and cultivation difficulty increase
Solution Approach 1:
The scape is divided into multiple branches (first scapes and second scapes) that arise from different nodes, allowing the plant to produce heavy flower show through distributed floral clusters rather than a single complex structure. This segmentation enables high productivity while maintaining manageable plant architecture.
Solution Approach 2:
The plant produces multiple scapes before the main flowering period, with first scapes developing from lower nodes and second scapes from upper nodes. This preliminary development of multiple flowering structures ensures continuous heavy flower show throughout the blooming period without requiring excessive post-flowering management.
2Illumination intensity
If flower color is intensified with more purple pigmentation, then aesthetic quality is improved, but flower size and petal development may be compromised
Solution Approach 1:
The flower color is intensified through increased purple pigmentation (anthocyanin concentration) while maintaining standard petal morphology. The deep violet to near-black coloration is achieved through genetic parameters related to pigment production rather than structural changes to petal shape or size, allowing both intense color and proper form to coexist.
3Area of stationary object
If foliage is made compact and smaller, then plant density is improved, but leaf surface area for photosynthesis is reduced
Solution Approach 1:
The foliage exhibits local variation in size and density, with smaller, more compact leaves at upper nodes and slightly larger leaves at lower nodes. This local quality differentiation allows the plant to maintain overall compactness for high density while preserving sufficient leaf surface area in lower regions for adequate photosynthesis.
