Thin Man Indiangrass Drought Tolerance via Crown Division
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ornamental plant varieties lack drought and heat tolerance, particularly in regions like the Southwestern United States, where prolonged drought and extreme heat are common, and there is a need for plants with attractive, vigorous, and drought-tolerant options that provide habitat and food sources for wildlife.
Innovation Solution
The development of the Sorghastrum nutans 'Thin Man' variety, characterized by blue foliage, upright and tightly growing habit, and exceptional drought and heat tolerance, achieved through chance genetic variation and propagation via crown division, which maintains uniformity and stability across different environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ornamental plant varieties are used, then they may have attractive foliage coloration, but they lack drought and heat tolerance
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific genetic parameters that confer drought and heat tolerance. The 'Thin Man' variety was identified through observation of genetic variations in Sorghastrum nutans plants, selecting individuals with superior tolerance parameters to extreme environmental conditions in the Southwestern United States.
Solution Approach 2:
The patent uses copying through asexual reproduction methods, specifically crown division, to propagate the selected 'Thin Man' variety. This allows the plant to reproduce true-to-type, maintaining the drought and heat tolerance characteristics across multiple generations without the variability introduced by seed propagation.
2Stability of the object's composition
If plants are propagated via seed, then genetic diversity is maintained, but uniformity and stability of characteristics are reduced
Solution Approach 1:
The patent employs copying through crown division, an asexual reproduction method, to produce uniform clones of the 'Thin Man' variety. This approach ensures that all propagated plants inherit the same genetic characteristics, including drought and heat tolerance, while maintaining true-to-type uniformity across generations.
Solution Approach 2:
The patent applies segmentation by dividing the parent plant into separate crown units through crown division. Each division creates an independent plantlet that can be propagated separately, allowing for controlled multiplication while maintaining genetic uniformity and stability of the desired characteristics.
3Reliability
If plants are grown in traditional nursery settings, then initial growth is supported, but long-term survival in extreme climate conditions is compromised
Solution Approach 1:
The patent applies self-service by selecting and propagating plants with inherent physiological adaptations to extreme climate conditions. The 'Thin Man' variety possesses intrinsic drought and heat tolerance characteristics that enable it to survive and thrive in the Southwestern United States without requiring intensive nursery intervention or special cultivation conditions long-term.

AI summary
‘Thin Man’ is a new and distinct plant variety of Sorghastrum nutans, more commonly known as yellow indiangrass or simply indiangrass. The new variety has blue foliage coloration instead of the more common green coloration; with a growth habit exhibiting an upright and tightly growing vegetation with apical flowering; and exceptional drought and heat tolerance.
