Hydrangea Galilee Cultivar Stem Strength and Blue Pigmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea macrophylla cultivars lack strong stems and vibrant blue sepals, with 'True Blue' requiring excessive aluminum for optimal pigmentation and 'Mathilda Gutges' having smaller florets and weaker stems.
Innovation Solution
The new cultivar 'Galilee' results from a controlled cross between Hydrangea macrophylla 'True Blue' and 'Mathilda Gutges', exhibiting stronger stems and larger florets with deeper blue sepals that develop without the need for excessive aluminum, achieved through asexual reproduction and fixed characteristics across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If 'True Blue' is used to achieve blue pigmentation, then the sepals develop blue tone, but excessive aluminum is required
Solution Approach 1:
The patent changes the genetic parameters of the hydrangea plant through controlled cross-breeding between 'True Blue' and 'Mathilda Gutges' parents. The resulting 'Galilee' cultivar has altered aluminum metabolism parameters that enable efficient blue pigmentation with reduced aluminum quantities, transforming the plant's biochemical parameters to resolve the contradiction between pigmentation intensity and aluminum requirement
Solution Approach 2:
The invention creates a composite genetic makeup combining traits from both parent varieties. The hybrid genotype integrates the blue pigmentation capability from 'True Blue' with the reduced aluminum requirement trait, effectively creating a composite biological system that achieves blue sepals without excessive aluminum application
2Strength
If 'Mathilda Gutges' is used, then the plant has good stem strength, but the florets are smaller
Solution Approach 1:
The patent merges the desirable stem strength trait from 'Mathilda Gutges' with the larger floret size trait from 'True Blue' through controlled cross-breeding. The hybrid 'Galilee' cultivar combines these two previously separate traits into a single plant variety, simultaneously achieving both strong stems and large florets that neither parent possessed alone
3Area of moving object
If 'True Blue' is used, then the florets are larger, but the stems are weaker
Solution Approach 1:
The invention merges the large floret size from 'True Blue' with the strong stem trait from 'Mathilda Gutges' through hybridization. The resulting 'Galilee' cultivar integrates these complementary traits, creating a plant that exhibits both large florets and strong stems, resolving the trade-off present in the parent varieties
4Adaptability or versatility
If conventional Hydrangea macrophylla cultivars are used, then the plants are commercially available, but they lack vibrant blue sepals and strong stems simultaneously
Solution Approach 1:
The patent changes the genetic parameters of commercially available hydrangea cultivars through controlled cross-breeding. The new 'Galilee' cultivar has modified genetic parameters that enable simultaneous expression of vibrant blue sepals and strong stems, improving the overall performance parameters while maintaining commercial viability through asexual reproduction

AI summary
A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘Galilee’ originated as a controlled cross between Hydrangea macrophylla (Thunb.) True Blue - U.S. Plant Pat. No. 18,593 (the seed parent), and the unpatented commercial variety Hydrangea macrophylla (Thunb.) ‘Mathilda Gutges’ (the pollen parent). The cultivar ‘Galilee’ can be blue or pink depending on the acidity of the soil. The new cultivar is characterized by its sturdy growth habit and its ability to produce blue pigmentation with relatively low levels of soil amendments. The new cultivar has showy inflorescences with large florets.
