Ceanothus FIT02 Cultivar with Purple Foliage and Vigorous Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Ceanothus that exhibits unique purple evergreen foliage and a vigorous bushy growth habit, suitable for temperate climates as an ornamental patio or contrast plant, which can survive mild winters and has stable and uniform foliage color.
Innovation Solution
The cultivar 'FIT02' of Ceanothus griseus var. horizontalis, discovered as a branch sport in a nursery-grown batch of Ceanothus griseus var. 'Autumnal Blue', is propagated through cuttings, showcasing chocolate brown and dark purple foliage, with a bushy and upright growth habit, and is suitable for temperate climates, surviving mild winters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new cultivar with unique purple evergreen foliage is developed through spontaneous mutation, then foliage color uniqueness is improved, but genetic stability and uniformity across propagations may be compromised
Solution Approach 1:
The inventor performed preliminary selection and evaluation of the spontaneous mutant plant before propagation, assessing its foliage color stability and growth characteristics over time. This preliminary action ensured that only plants with stable genetic expression were selected for propagation, preventing genetic instability from being introduced into the cultivar population
Solution Approach 2:
The unique foliage color trait was copied through asexual propagation via cuttings, which preserves the exact genetic composition of the parent plant. This copying method ensures that the unique purple evergreen foliage is replicated uniformly across all propagations without genetic variation, maintaining both uniqueness and stability
2Ease of manufacture
If the cultivar is selected for vigorous bushy growth habit, then ornamental value is improved, but plant size control becomes more difficult
Solution Approach 1:
The cultivar exhibits local quality in its growth pattern, with dense branching concentrated in the lower and middle portions of the plant while the upper portions maintain a more open structure. This localized density variation provides both the vigorous bushy appearance for ornamental value and natural size control, preventing the plant from becoming uniformly dense and difficult to manage
Solution Approach 2:
The plant's growth habit is dynamic rather than static, with the vigorous bushy growth occurring primarily during the active growing season while natural pruning and dieback occur in winter. This dynamic growth pattern allows the plant to achieve ornamental value during favorable periods while naturally controlling size through seasonal cycles
