Mangave Hybrid 'Permanent Wave' Compact Habit and Glaucous Leaves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a Mangave plant that combines the unique characteristics of compact growth, ovate to ovate-deltoid leaves, intense glaucousness, and moderate growth rate, which are distinct from its parents and other known Mangave, Agave, and Manfreda species.
Innovation Solution
A new Mangave hybrid, 'Permanent Wave', is developed by crossing proprietary Mangave 12-11-1 as the female parent and Agave ovatifolia as the male parent, exhibiting a compact mounded habit, dense overlapping leaves with large marginal teeth, and a moderate growth rate, achieved through asexual propagation using shoot tip tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Mangave, Agave, and Manfreda species are used, then they have established growth patterns and characteristics, but they lack the specific combination of compact growth, ovate to ovate-deltoid leaves, intense glaucousness, and moderate growth rate
Solution Approach 1:
The patent combines specific traits from two parent species (Agave ovatifolia and another Agave species) through controlled hybridization to create a new Mangave cultivar that exhibits a unique combination of compact growth habit, ovate to ovate-deltoid leaves, intense glaucousness, and moderate growth rate that neither parent possesses alone
Solution Approach 2:
The hybridization process changes key morphological parameters including leaf shape (ovate to ovate-deltoid), surface characteristics (intense glaucousness), growth rate (moderate), and overall habit (compact mounded) to produce a distinct phenotype that differs from both parent species
2Productivity
If rapid growth is achieved in Mangave plants, then productivity increases, but the plant loses the compact mounded habit and moderate growth rate characteristics
Solution Approach 1:
The patent identifies and selects for specific parameter combinations in the hybrid that result in moderate growth rate while maintaining compact mounded habit, demonstrating that growth rate and plant shape are interrelated parameters that can be simultaneously optimized through controlled breeding
3Ease of manufacture
If leaves are made more glaucous and densely overlapping, then aesthetic appeal improves, but the leaf structure becomes more complex
Solution Approach 1:
The patent enhances specific local qualities of the leaves including intense glaucousness (waxy coating), dense overlapping arrangement, and ovate to ovate-deltoid shape, creating aesthetic appeal through localized trait enhancement rather than overall structural complexity

AI summary
A new and unique X Mangave plant named ‘Permanent Wave’ is characterized by a compact mounded habit of ovate to deltoid-ovate leaves with dense, overlapping, intensely-glaucous, light-gray color. The new plant has large marginal teeth ending in a small, sharp, firm tooth and a large firm sharp apical mucro. The foliage frequently has depression images of the teeth left in the tops and bottoms of the leaves. The new plant has a moderate growth rate. The new plant is suitable as a potted houseplant plant, as a container plant for the patio or garden, and for the garden or planted in the landscape.
