Dianthus Cultivar With Double White Flowers and Extended Bloom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Dianthus cultivars lack distinct traits such as double flowers with pure white petals, a compact habit, and prolonged flowering periods, which are not consistently exhibited across varying environmental conditions.
Innovation Solution
Development of the Dianthus 'Whipped Cream' cultivar, which features double flowers with pure white petals, a compact habit, and prolonged flowering from late spring to early fall, achieved through asexual propagation and sterile shoot-tip tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Dianthus cultivars are used, then they have simpler flower structures and smaller sizes, but they lack double flowers with pure white petals and compact habit
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including double flower structure, pure white petal color, compact plant habit, and finely dentate to crenate petal apices. These parameter selections transform the original Dianthus characteristics into the desired 'Whipped Cream' cultivar traits through controlled breeding and selection processes
2Duration of action of moving object
If Dianthus cultivars are bred for larger flowers, then flower size increases, but flowering period shortens and plant habit becomes less compact
Solution Approach 1:
The patent simultaneously optimizes multiple parameters including flowering duration (prolonged from late spring to early fall), plant height (compact at 6-12 inches), and flower structure (double flowers). This multi-parameter optimization resolves the trade-off between flowering period duration and plant compactness through selective breeding
3Reliability
If Dianthus cultivars are propagated traditionally, then propagation is simpler, but phenotypic consistency across environments is not maintained
Solution Approach 1:
The patent employs tissue culture techniques to create exact genetic copies of the selected Dianthus plant. This copying process ensures that the phenotypic traits (double flowers, pure white petals, compact habit) are precisely replicated across multiple plants, maintaining phenotypic consistency while enabling commercial-scale propagation

AI summary
A new and unique plant cultivar of perennial carnation or pinks, Dianthus plant named ‘Whipped Cream’, with numerous highly-branched stems producing double, lightly-sweet fragrant flowers producing a full rounded face. Each flower has about twenty-two overlapping petals that are pure white with a small light-pink bar. Petals have finely dentate to crenate apices and margins. Flowering season is strong beginning in late spring and continues less densely to early-fall. The habit is compact and dense with glaucous silver-blue foliage.
