Bandera Helenium Cultivar Uniform Mounding Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and freely-flowering Helenium plants with attractive ray and disc colors, as existing varieties do not meet the requirements for uniform mounding and vibrant bi-colored inflorescences.
Innovation Solution
A new cultivar, 'Bandera', was developed through open-pollination, characterized by a compact, uniformly mounding habit, moderately vigorous growth, and bi-colored dark yellow and dark orange ray florets, with strong peduncles holding inflorescences above the foliar plane, achieved through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Helenium varieties are used, then they have certain growth habits, but they lack uniform mounding and compactness
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific growth parameters that result in uniform mounding habit. The 'Bandera' cultivar exhibits a compact, broadly upright and uniformly mounding plant habit with a height-to-width ratio of approximately 0.68, representing optimized dimensional parameters that resolve the contradiction between uniform shape and adaptability.
2Ease of manufacture
If existing Helenium varieties are used, then they have certain flowering characteristics, but they lack vibrant bi-colored inflorescences
Solution Approach 1:
The patent applies local quality by creating inflorescences with distinct bi-colored ray florets where different parts of the same flower exhibit different colors. The 'Bandera' cultivar features ray florets with dark yellow to orange-yellow apical thirds and orange to red-orange basal thirds, providing localized color variation that enhances aesthetic appeal while maintaining vigorous flowering.
3Strength
If existing Helenium varieties are used, then they have certain peduncle strength, but they fail to hold inflorescences above the foliar plane
Solution Approach 1:
The patent applies parameter changes by optimizing peduncle structural parameters including strength, thickness, and length to achieve the desired positioning. The 'Bandera' cultivar exhibits strong peduncles that are sufficiently thick and rigid to support inflorescences above the foliar plane, with peduncles that are both strong enough to hold position and long enough to elevate flowers for optimal display.
