Veronica Verpurg Plant Breeding Merging Compact Habit and Violet Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Veronica spicata that exhibits a compact and dwarf plant habit, numerous flowering stems, a long bloom season, and intense violet-purple flowers, as existing cultivars like 'Verspi' and 'Purpleicious' differ in flower color and bloom duration.
Innovation Solution
The cultivar 'Verpurg' is developed through open pollination of Veronica 'Verspi', characterized by a compact dwarf habit, numerous flowering stems, re-blooming habit, and intense violet-purple flowers, achieved through asexual propagation by stem cuttings, which are stable and true to type in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If Veronica 'Verspi' is used as the basis for breeding, then compact dwarf habit and floriferous blooming are achieved, but flower color remains pink instead of violet-purple
Solution Approach 1:
The patent merges two distinct trait sets from different parent plants: the compact dwarf habit and floriferous blooming from Veronica 'Verspi' (female parent) with the violet-purple flower color from an unknown male parent through open pollination, creating a new cultivar that combines these previously separate characteristics
2Ease of manufacture
If Veronica spicata 'Purpleicious' is used, then violet-purple flowers are achieved, but bloom period is shorter and plant height is greater
Solution Approach 1:
The patent combines the violet-purple flower color trait from Veronica spicata 'Purpleicious' with the extended bloom period and compact dwarf habit from Veronica 'Verspi', creating a superior cultivar that exhibits all three desirable traits simultaneously through controlled open pollination
3Ease of manufacture
If Veronica spicata 'Purpleicious' is used, then violet-purple flowers are achieved, but plant height is taller rather than compact
Solution Approach 1:
The patent merges the violet-purple flower color from Veronica spicata 'Purpleicious' with the compact dwarf habit from Veronica 'Verspi', resulting in a cultivar that achieves both the desired color intensity and the compact plant architecture suitable for landscape use
4Adaptability or versatility
If open pollination is used for breeding, then genetic diversity and new trait combinations are achieved, but male parent identity is unknown
Solution Approach 1:
The patent utilizes the natural self-service mechanism of open pollination where the plant independently completes the breeding process through natural pollinators, achieving genetic diversity and new trait combinations without requiring human intervention for controlled crossing, though this results in unknown male parent identity
