Hydrangea Glory Cultivar Non-Pigmented Sepals Drought Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea varieties face issues with sepals turning brown under drought and aging, leading to short-lived blooms and poor branching characteristics, which affects their aesthetic value and durability.
Innovation Solution
The new Hydrangea macrophylla 'Glory' cultivar, resulting from a controlled cross between 'Snowball' and 'Libelle', exhibits non-pigmented sepals that remain resistant to browning under moderate drought and aging, combined with a compact growth habit and easy branching, producing long-lasting, uniform blooms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing Hydrangea varieties are used, then they produce blooms, but the sepals turn brown under drought and aging conditions, reducing bloom longevity
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that alter the biochemical composition of sepals. The 'Glory' cultivar has been bred to have non-pigmented sepals with modified chemical parameters that prevent browning reactions under drought and aging conditions, thereby extending bloom longevity without requiring external interventions.
2Ease of operation
If existing Hydrangea varieties are used, then they grow, but they exhibit poor branching characteristics when pinched, affecting aesthetic value
Solution Approach 1:
The patent utilizes parameter changes by breeding the 'Glory' cultivar with specific growth parameters that respond optimally to pinching. The plant has been selected to exhibit enhanced lateral bud activation and compact growth parameters when apical dominance is removed through pinching, resulting in improved branching characteristics and uniform aesthetic appearance.
3Manufacturing precision
If existing Hydrangea varieties are used, then they produce flowers, but the blooms are not uniform in dimension, reducing showiness
Solution Approach 1:
The patent applies parameter changes by breeding the 'Glory' cultivar with genetically determined parameters that control flower development. The plant exhibits uniform petal number, size, and shape parameters due to selective breeding, creating showy and consistent blooms that meet commercial quality standards.
4Volume of moving object
If existing Hydrangea varieties are used, then they grow to maturity, but they have tall and less compact forms, increasing space requirements
Solution Approach 1:
The patent utilizes parameter changes by selecting and breeding plants with modified growth parameters. The 'Glory' cultivar has been bred to exhibit compact growth parameters including shorter internode lengths, reduced overall plant height, and a more condensed branching structure, thereby reducing space requirements while maintaining aesthetic appeal.

AI summary
A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘Glory’ originated as a controlled cross. The cultivar ‘Glory’ has non-pigmented sepalous florets and is desirable for its compact and sturdy growth habit. ‘Glory’ has large showy inflorescences, having both sepalous and non-sepalous florets, dominated non-sepalous florets.
