Ruby Tuesday Helenium Compact Freely Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Helenium cultivars lack a double inflorescence form and long flowering period, with limited compact and freely flowering options with dark red-colored ray florets.
Innovation Solution
The development of the Helenium hybrida cultivar 'Ruby Tuesday' through controlled cross-pollination, characterized by an upright, compact, and freely flowering habit with dark red ray florets and strong peduncles, maintaining flower color and substance for an extended period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional Helenium cultivars are used, then they have larger inflorescences, but they lack compact plant form and long flowering period
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific genetic traits that simultaneously achieve compact plant form (changing growth habit parameters) and extended flowering duration (changing temporal parameters). The cultivar 'Ruby Tuesday' exhibits these altered parameters through controlled cross-pollination and selection, resolving the contradiction between plant size and flowering period.
2Shape
If conventional Helenium cultivars are used, then they have simpler inflorescence form, but they lack double inflorescence structure
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: initial cross-pollination of parent selections, identification of progeny with double inflorescence form, and subsequent asexual reproduction to stabilize the trait. This segmented approach allows the complex double inflorescence structure to be developed and fixed systematically through controlled breeding steps.
3Ease of manufacture
If conventional Helenium cultivars are used, then they have limited flower color variation, but they lack dark red-colored ray florets
Solution Approach 1:
The patent applies self-service through asexual reproduction by terminal cuttings, which allows the cultivar to self-maintain its dark red coloration and other desired traits without further intervention. Once the desired color phenotype is established through breeding, the plant propagates itself true-to-type, ensuring color stability and intensity are preserved across generations without additional breeding complexity.

AI summary
A new and distinct cultivar of Helenium plant named ‘Ruby Tuesday’, characterized by its upright, somewhat outwardly spreading and uniform plant habit; moderately vigorous growth habit; freely flowering habit; inflorescences with dark red-colored ray florets; and strong peduncles that hold the inflorescences above the foliar plane.
