Helenium Cultivar Dwarf Habit Early Bloom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Helenium autumnale cultivars lack a dwarf plant habit, early blooming, and continuous new bloom production, with limited color variation in ray florets.
Innovation Solution
The development of 'Short 'n' Sassy', a new Helenium cultivar characterized by a dwarf plant habit, early blooming, continuous production of new bloom stalks, and inflorescences with a unique yellow and red color blend, achieved through asexual reproduction by stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional Helenium autumnale cultivars are used, then they produce blooms, but they reach excessive height (not dwarf habit) and bloom later in the season
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a mutant plant with altered growth parameters. The new cultivar 'Short 'n' Sassy' exhibits a dwarf habit (reaching only 45-56 cm in height compared to typical taller cultivars) and early blooming characteristic (2-3 weeks earlier than most Helenium autumnale cultivars). This represents a fundamental change in the plant's growth parameters through natural mutation and selective propagation via stem cuttings.
2Duration of action of moving object
If traditional Helenium autumnale cultivars are used, then they produce a single blooming flush, but they do not continuously produce new bloom stalks above spent blooms
Solution Approach 1:
The patent implements continuity of useful action through the unique growth habit of 'Short 'n' Sassy' where new bloom stalks continuously emerge and rise above the plane of spent blooms. This allows the plant to maintain an active blooming front throughout its blooming period (8-10 weeks), with successive waves of flower production rather than a single flush followed by complete senescence. The plant effectively resets its blooming cycle multiple times.
3Quantity of substance
If traditional Helenium autumnale cultivars are used, then they have standard ray floret colors, but they lack the unique yellow and red color blend creating orange effect
Solution Approach 1:
The patent applies parameter changes in the floral coloration through a unique pigmentation pattern in the ray florets. The 'Short 'n' Sassy' cultivar displays ray florets with a blend of yellow and red colors that create an orange effect, distinct from the solid yellow or other single-color presentations of traditional cultivars. This color parameter was established through natural mutation and is now stably inherited through asexual propagation.
4Stability of the object's composition
If asexual reproduction by stem cuttings is used, then true-to-type reproduction is achieved, but it requires specific propagation techniques and time
Solution Approach 1:
The patent implements preliminary action by performing propagation activities during the optimal growing season (August 2009 in the case of the first cuttings). By taking stem cuttings during active growth periods when environmental conditions are favorable, the propagation process is accelerated and success rates are maximized. This timing strategy reduces the overall propagation time while ensuring true-to-type reproduction of the dwarf, early-blooming characteristics.

AI summary
A new cultivar of Helenium, ‘Short ‘n’ Sassy’, characterized by its dwarf plant habit; reaching 45 to 56 cm in height, its early commencement of bloom with new blooming stems continuously produced that rise above the older spent blooms and its inflorescences with ray florets that are a blend of yellow and red in color creating a yellow and orange effect.
