Hydrangea BCHY-11.033 Compact Inflorescence Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cultivars of Hydrangea macrophylla lack a suitable growth habit for commercial production of ornamental potted plants, with inflorescences that are not compact or attractive enough to hide non-sepalous florets effectively.
Innovation Solution
The new cultivar 'BCHY-11.033' results from a controlled cross between '8.1' and 'BC8.3', featuring compact, attractive inflorescences with large sepalous florets that surround non-sepalous florets, stable asexual reproduction, and improved commercial characteristics such as strong stems and unique sepal pigmentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If current cultivars of Hydrangea macrophylla are used, then they have inflorescences that are not compact or attractive enough, but they lack the ability to effectively hide non-sepalous florets
Solution Approach 1:
The patent applies local quality by developing a cultivar with non-uniform sepal pigmentation where different regions of the sepal display different colors and intensities. The upper side shows vibrant violet-red pigmentation while the lower side and margins exhibit different coloration patterns, creating visual depth and attractiveness that enhances the inflorescence's ability to hide non-sepalous florets.
2Shape
If a cultivar with large sepalous florets is developed to hide non-sepalous florets, then the inflorescence becomes more attractive, but the stem strength may be compromised
Solution Approach 1:
The patent merges multiple desirable traits from different parent cultivars into a single unified variety. It combines the large sepalous florets and attractive pigmentation from one parent with the strong stem structure and vigorous growth habit from another parent, achieving a balance where both aesthetic qualities and structural strength are present in the same plant.
3Shape
If a cultivar with unique sepal pigmentation is created, then commercial attractiveness improves, but stability of characteristics during asexual reproduction may be affected
Solution Approach 1:
The patent applies self-service by demonstrating that the cultivar maintains its unique pigmentation characteristics through stable asexual reproduction via cuttings. The non-uniform pigmentation pattern, with its specific distribution of colors across the sepal surface, reproduces consistently without requiring external intervention or special conditions, making the cultivar commercially viable.

AI summary
A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘BCHY-11.033’ originated as a controlled cross between varieties. The variety ‘BCHY-11.033’ has attractive inflorescences with relatively large sepalous florets, attractive, nonuniform sepal pigmentation and good commercial characteristics. Many non-sepalous florets in the center of the inforescence make the new variety look similar to a lace-cap variety.
