Hydrangea KOLMAKILIMA Short Strong Stems Mophead Blooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea paniculata cultivars lack short and strong stems with mophead-like blooms, which are desirable for landscape use, and existing varieties often have longer stems and smaller inflorescences or less showy sterile flowers.
Innovation Solution
The development of the new cultivar 'KOLMAKILIMA' with short and strong stems and mophead-like, long, conical inflorescences, achieved through asexual propagation by stem cuttings, which reproduces true to type in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Hydrangea paniculata cultivars are used, then they have longer stems, but they lack short and strong stems with mophead-like blooms
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants with specific genetic traits that result in shortened stem length while simultaneously developing mophead-like inflorescence characteristics. The cultivar 'KOLMAKILIMA' exhibits stem lengths of 3-6 inches compared to traditional varieties with longer stems, achieved through controlled pollination and selection of parent plants with desirable traits.
2Length of moving object
If existing Hydrangea cultivars with shorter stems are developed, then stem length is reduced, but inflorescences become smaller
Solution Approach 1:
The patent achieves asymmetry in the plant architecture by creating a disproportionate relationship between stem length and inflorescence size. The cultivar 'KOLMAKILIMA' has unusually short stems (3-6 inches) that support relatively large mophead-like inflorescences, breaking the typical correlation where longer stems support larger flower heads. This asymmetric development is achieved through specific genetic selection of parent plants.
3Shape
If stem length is reduced for landscape use, then plant compactness is improved, but stem strength may be compromised
Solution Approach 1:
The patent applies local quality by enhancing specific properties of the stem tissue in the cultivar 'KOLMAKILIMA'. The stems exhibit increased thickness and structural reinforcement at critical locations despite overall short length, providing both compact plant habit and adequate stem strength to support the weight of large mophead-like inflorescences. This localized strengthening is achieved through selective breeding.
