Hydrangea COF-HM1 Rebloom and Cold Hardiness Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea macrophylla cultivars lack optimal rebloom potential, cold hardiness, and flower production, with slower production cycles and less robust growth habits compared to the new cultivar 'COF-HM1'.
Innovation Solution
The cultivar 'COF-HM1' exhibits unique traits such as extreme floriferousness, increased rebloom potential on both new and old wood, enhanced cold hardiness, compact growth habit, and rapid color change to blue with aluminum treatment, distinguishing it from other varieties like 'Bailmer' and 'Monmar'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Hydrangea macrophylla cultivars are used, then they have moderate flower production and slow growth, but they lack extreme floriferousness, rapid rebloom, and enhanced cold hardiness
Solution Approach 1:
The patent describes a newly discovered cultivar 'COF-HM1' with genetically determined traits that differ from conventional cultivars in multiple parameters simultaneously - extreme floriferousness, rapid rebloom capability, enhanced cold hardiness, and compact growth habit. This represents a fundamental parameter change in the cultivar's inherent characteristics rather than environmental modification.
2Productivity
If conventional Hydrangea cultivars are used, then they have moderate rebloom potential, but the new cultivar achieves rapid rebloom on both new and old wood
Solution Approach 1:
The cultivar 'COF-HM1' possesses genetically predetermined capabilities for rapid rebloom on both new and old wood, allowing the plant to prepare and execute flowering cycles more quickly than conventional cultivars. This preliminary physiological preparation enables faster production cycles without sacrificing flower quality.
3Reliability
If conventional Hydrangea cultivars are used, then they have moderate cold hardiness, but the new cultivar demonstrates enhanced cold hardiness for a remontant variety
Solution Approach 1:
The patent describes a newly discovered cultivar 'COF-HM1' with genetically determined traits that differ from conventional cultivars in multiple parameters simultaneously - extreme floriferousness, rapid rebloom capability, enhanced cold hardiness, and compact growth habit. This represents a fundamental parameter change in the cultivar's inherent characteristics rather than environmental modification.
4Area of stationary object
If conventional Hydrangea cultivars are used, then they have larger plant size, but the new cultivar maintains a compact habit suitable for container growth
Solution Approach 1:
The cultivar 'COF-HM1' exhibits a compact growth habit with densely branched architecture, concentrating its floriferous potential within a smaller spatial footprint. This local modification of growth pattern allows the plant to maintain high flower production while occupying less overall space, making it ideal for container cultivation.

AI summary
A new and distinct Hydrangea cultivar named ‘COF-HM1’ is disclosed, characterized by compact plants producing mop-head inflorescences with pink or blue flowers, depending upon the absence or presence of aluminum. Plants are well-suited to commercial applications, having a rapid production cycle. Rebloom potential is increased in plants of the new variety, which rebloom on both new growth and old wood. Plants of the new variety are cold hardy and bloom abundantly. The new variety is a Hydrangea, normally produced as an ornamental plant.
