Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Hydrangea varieties with compact plant habits and specific panicle characteristics that are not met by existing cultivars, particularly in terms of panicle shape, flower color progression, and plant size.
Innovation Solution
The cultivar 'COUHAMINT' exhibits globular shaped panicles that age from green to green-white, brown stem color, and a compact, v-shaped plant habit, achieved through asexual reproduction by softwood cuttings, distinguishing it from other Hydrangea varieties like 'Limelight'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Hydrangea varieties are used, then they exhibit vigorous growth and large plant size, but they lack compact plant habits and globular panicle shapes
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific genetic traits that produce compact growth habits and globular panicle shapes. Through controlled breeding and asexual reproduction via softwood cuttings, the cultivar 'COUHAMINT' maintains stable parameters for plant height (70-80 cm), spread (60 cm), and panicle shape (globular), distinguishing it from conventional vigorous varieties.
2Ease of manufacture
If existing Hydrangea cultivars are selected, then they offer variety in flower color, but they do not exhibit the specific green-to-white aging progression with strong green color
Solution Approach 1:
The patent applies preliminary action through a systematic breeding program conducted before the cultivar's discovery. The inventor performed planned crossings, selected progeny with desired traits, and propagated them through softwood cuttings to establish the stable flower color characteristics. This preliminary breeding work ensured the reliable green-to-white aging progression and strong green coloration are consistently reproduced in 'COUHAMINT'.
