Hydrangea COUMONT Cultivar Traits and Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Hydrangea cultivar that combines unique characteristics such as dense flowerheads, bronze fall foliage, and adaptability to various environmental conditions, while maintaining stability through asexual reproduction.
Innovation Solution
The development of the Hydrangea cultivar 'COUMONT', resulting from a cross between Hydrangea serrata 'Santiago' and Hydrangea macrophylla 'The Bride', which exhibits mophead inflorescences, compact growth, tolerance to cold, and adaptability to both full sun and partial shade, with stable reproduction through softwood cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Hydrangea serrata 'Santiago' and Hydrangea macrophylla 'The Bride' are crossed to create new cultivar, then unique characteristics such as dense flowerheads and bronze fall foliage are achieved, but genetic stability and true-to-type reproduction must be ensured
Solution Approach 1:
The patent employs asexual reproduction through softwood cuttings to create exact genetic copies of the new cultivar 'COUMONT'. This copying method ensures that the unique characteristics (dense mophead inflorescences, bronze fall foliage, compact growth) are precisely replicated in successive generations without genetic variation, resolving the contradiction between achieving unique traits through crossing and maintaining genetic stability through reproduction.
2Shape
If the cultivar is bred for dense mophead inflorescences and compact growth, then aesthetic value and space efficiency are improved, but adaptability to different environmental conditions must be maintained
Solution Approach 1:
The new cultivar 'COUMONT' exhibits multi-functionality by simultaneously achieving compact globular growth habit and broad environmental adaptability. The plant maintains its compact shape (100-150 cm height) while tolerating diverse conditions including full sun to partial shade, temperatures from -30°C to 35°C, and various soil types, making it universally suitable for different gardening environments without sacrificing its aesthetic form.
3Duration of action of stationary object
If the inflorescence is designed for long-lasting durability in rain and as cut flowers, then commercial value is improved, but the complexity of achieving both structural strength and aesthetic appeal increases
Solution Approach 1:
The inflorescence of 'COUMONT' functions as a composite structure combining sterile florets with prominent sepals that together create the dense mophead form. The sepals provide structural strength and water resistance for durability in rain and as cut flowers, while the composite nature of the inflorescence (sterile flowers + persistent sepals) achieves both aesthetic appeal and extended longevity without requiring complex additional structures.
Data Source
AI summary
A new and distinct Hydrangea cultivar named ‘COUMONT’ is disclosed, characterized mophead inflorescences composed of yellow-green and pink flowers. Plants flower abundantly on same year's growth. Inflorescences and individual flowers hold up well in the rain and plants tolerate both full sun and partial shade. Plants are compact, well-branched and have large foliage. The new variety is a Hydrangea, normally produced as an ornamental plant for containers or gardens.
