Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Weigela cultivars lack attractive, dark foliage and robust hardiness, with limited tolerance to varying environmental conditions and pruning requirements.
Innovation Solution
The development of Weigela florida 'WFMOBLA' cultivar, characterized by attractive glossy dark burgundy-black foliage, excellent hardiness, and a low-mounded habit requiring minimal care, achieved through a breeding program focusing on improved production performance and stability across environmental variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Weigela cultivars are used, then they have basic foliage characteristics, but they lack attractive dark foliage and glossiness
Solution Approach 1:
The breeding program changed the genetic parameters of the Weigela plant to produce dark burgundy-black foliage with high glossiness. This involved selecting and crossing plants with desirable foliage traits to stabilize the dark coloration and glossiness characteristics across generations, transforming the foliage appearance parameters while maintaining environmental adaptability
2Reliability
If existing Weigela cultivars are used, then they have average hardiness, but they lack excellent hardiness and disease resistance
Solution Approach 1:
The new cultivar exhibits self-service characteristics through its excellent hardiness and disease resistance, requiring minimal human intervention for maintenance. The plant naturally resists diseases and adapts to environmental conditions without requiring intensive care, pruning, or protective treatments, thereby improving reliability while reducing operational complexity
3Ease of operation
If existing Weigela cultivars are used, then they require regular pruning to maintain shape, but the new cultivar requires minimal care or pruning
Solution Approach 1:
The new cultivar displays a dynamic low-mounded growth habit that naturally maintains its shape through its inherent growth pattern rather than requiring external pruning intervention. The plant adapts its form through natural growth dynamics, creating a self-regulating system that preserves aesthetic shape while minimizing maintenance operations

AI summary
A new and distinct Weigela cultivar named ‘WFMOBLA’ is disclosed, characterized by a low, mounded plant habit requiring little pruning to maintain shape. Plants are very cold hardy and produce attractive glossy dark foliage. Dark foliage appears in the Spring when overwintered in a poly-house. The new. variety is a Weigela, normally produced as an outdoor garden or container plant.
