Clematis Evipo042 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant purple flowers, vigorous and compact growth suitable for container culture, and improved disease resistance.
Innovation Solution
A new Clematis variety 'Evipo042' was developed through controlled crossing, characterized by purple flowers, compact growth habit, and enhanced disease resistance, achieved through asexual reproduction by vegetative cuttings and traditional layering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clematis varieties are used in commercial cultivation, then they have been available for gardening use, but they lack uniform and abundant purple flowers, vigorous and compact growth suitable for container culture, and improved disease resistance
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including compact growth habit, uniform purple flower color, and disease resistance. The hybridization process modifies genetic parameters to achieve a combination of qualities that were previously lacking in commercial clematis varieties, creating a plant that is both adaptable to container culture and resistant to diseases
Solution Approach 2:
The patent creates a composite genetic structure through controlled crossing between selected parent plants. The new variety 'Evipo042' combines desirable traits from multiple parents including compact growth habit, uniform purple flowering, and disease resistance, resulting in a composite plant that exhibits all three qualities simultaneously
2Productivity
If clematis plants are bred for vigorous growth, then they produce more abundant flowers, but they become less compact and less suitable for container culture
Solution Approach 1:
The patent modifies growth parameters through selective breeding to achieve a unique combination where the plant exhibits vigorous flowering productivity while maintaining a compact overall size. The new variety produces abundant flowers on a confined framework, changing the relationship between plant size and flower abundance that typically exists in traditional varieties
3Manufacturing precision
If clematis plants are bred for uniform flower color, then they meet commercial aesthetic standards, but they lack the vigor and compact growth needed for modern cultivation methods
Solution Approach 1:
The patent creates a composite genetic makeup that combines genes for uniform purple flower coloration with genes for vigorous and compact growth. The resulting variety 'Evipo042' exhibits both uniform aesthetic qualities and strong productive growth, merging traits that were previously mutually exclusive in commercial clematis varieties

AI summary
A new Clematis plant with a compact growth habit, profuse, purple flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation commercial glasshouse and nursery culture. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation from vegetative cuttings.
