Trailing Viola Cultivar with Compact Habit and Red Pansy Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of commercially available trailing Viola×wittrockiana cultivars with unique red flower coloration, compact growth habit, and large, round 'pansy' flower forms, which are stable across varying environmental conditions.
Innovation Solution
The development of the cultivar 'KERVIODEEP', resulting from crossing proprietary seedlings '05-66-4' and '05-66-5', exhibits a distinct combination of traits including a spreading, trailing habit, exceptionally compact growth, large round flowers with a unique red color, and is propagated through vegetative cuttings, ensuring stability across different environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional trailing Viola×williamsii are used, then spreading growth habit is achieved, but flower form is elongated rather than round 'pansy' shape
Solution Approach 1:
The patent merges two previously separate traits into one cultivar: the round 'pansy' flower form (typically found in Viola×wittrockiana) and the trailing growth habit (typically found in Viola×williamsii). This combination was achieved through a planned breeding program that crossed selected parent plants to produce KERVIODEEP, which simultaneously exhibits both the round flower morphology and the trailing growth pattern.
2Ease of manufacture
If red flower coloration is introduced in trailing Viola, then unique color is achieved, but stability across environmental conditions may be compromised
Solution Approach 1:
The stability of the red flower coloration was established through preliminary breeding actions. The inventors performed a planned breeding program that crossed selected parent plants, then selected and propagated the desired red coloration trait through vegetative cuttings. This preliminary establishment of the trait through controlled breeding and vegetative propagation ensures the color remains stable across varying environmental conditions.
3Area of moving object
If large flower size is achieved, then ornamental value is improved, but plant compactness may be reduced
Solution Approach 1:
The patent applies local quality by concentrating the large flower size specifically in the floral portions of the plant while maintaining compact overall plant dimensions. The KERVIODEEP cultivar produces large, showy flowers that stand out against a compact trailing framework, creating a localized emphasis on floral display without requiring the entire plant structure to be large or bulky.

AI summary
A new and distinct Viola×wittrockiana cultivar named ‘KERVIODEEP’ is disclosed, characterized, by a unique combination of a large, round “pansy” type flower, found on a trailing plant. Flower color is a deep red. Plants have a compact, trailing plant habit. The new variety is a Viola×wittrockiana, suitable for outdoor landscape and container use.
