Buddleja Tobudviole Compact Habit and Extended Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Buddleja davidii cultivars lack distinct characteristics such as compact habit, shorter internodes, and extended flowering seasons, with limited options for gardeners seeking lighter purple flowers and increased flower production.
Innovation Solution
The development of the Buddleja davidii cultivar 'Tobudviole', which exhibits short internodes, conical flower spikes, compact habit, small leaves, and a long flowering season, distinguished by lighter purple flowers, earlier flowering, and a more compact habit compared to 'Nanho Purple' and its female parent BUO3049.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Buddleja davidii cultivars are used, then they have established growth patterns, but they lack compact habit and have long internodes
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that result in shortened internodes and compact growth habit. The cultivar 'Tobudviole' exhibits internodes of 3 cm compared to longer internodes in existing cultivars, achieving the desired compact shape through genetic parameter modification rather than physical constraint.
2Duration of action of moving object
If existing Buddleja davidii cultivars are used, then they have standard flowering duration, but they lack extended flowering seasons
Solution Approach 1:
The patent achieves continuous flowering from June to November through selective breeding that extends the flowering period. The cultivar 'Tobudviole' produces flowers continuously over this extended period with multiple flushes, ensuring uninterrupted ornamental value and sustained productivity throughout the growing season.
3Ease of manufacture
If existing Buddleja davidii cultivars are used, then they have standard flower color intensity, but they lack lighter purple flower variations
Solution Approach 1:
The patent applies local quality by developing a cultivar with specific lighter purple flower coloration (Royal Horticultural Society colour chart 82B-82D) that differs from the darker purple of parent cultivars. This localized color modification provides gardeners with a distinct visual option for specific design applications while maintaining the species' overall characteristics.
4Duration of action of moving object
If Buddleja 'Nanho Purple' is used, then it has established performance characteristics, but it has darker purple flowers and later flowering time
Solution Approach 1:
The patent applies preliminary action by selecting plants that flower earlier in the season and breeding them to establish an extended flowering period. The cultivar 'Tobudviole' begins flowering in June compared to later flowering in 'Nanho Purple', and maintains flowering through November, effectively preparing and extending the flowering period across the growing season.
