Hydrangea Dancing Angel Variegated Foliage Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Hydrangea macrophylla that exhibits unique characteristics such as variegated foliage and bi-colored flowers, which are not present in existing cultivars like Pink Candy and Kumiko, and can thrive under varying environmental conditions.
Innovation Solution
The cultivar 'Dancing Angel' is a naturally occurring branch mutation of Hydrangea macrophylla 'Pink Candy' with upright and mounded growth habit, strong roots and stems, dark green leaves with autumnal variegation, and large mophead-type inflorescences featuring pink and red-purple bi-colored flowers, which are stable through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new Hydrangea cultivar with unique characteristics is developed through natural mutation, then distinctive foliage and flower colors are achieved, but the rarity and instability of such traits make consistent reproduction difficult
Solution Approach 1:
The cultivar was discovered and selected through preliminary observation and screening of natural mutations in a controlled environment, identifying the specific branch mutation that exhibited the desired variegated foliage and bi-colored flower traits before formal propagation began
Solution Approach 2:
Asexual reproduction through softwood cuttings creates genetic copies of the mutant plant, ensuring that the unique variegated foliage and bi-colored flower characteristics are faithfully reproduced in successive generations without the variability associated with sexual reproduction
2Volume of moving object
If the cultivar is bred to have compact growth habit, then space efficiency is improved, but the size of leaves and flowers may be reduced
Solution Approach 1:
The cultivar exhibits a compact growth habit with controlled plant dimensions (about 35 cm height and 40 cm spread) while maintaining moderate leaf size (about 10.5 cm length) and flower size (about 17 cm panicle diameter), achieving a balance through natural mutation rather than extreme breeding selection
