Sweet Bubba Desert Willow Cultivar Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Chilopsis linearis cultivars lack a combination of desirable traits such as upright growth form, consistent blooming throughout the warm season, fast growth rate, dark green leaves, seedlessness, and distinctive red/purple flower color, which are not adequately met by existing varieties.
Innovation Solution
A new cultivar, 'Sweet Bubba', resulting from a cross between Chilopsis linearis 'Sweet Katie Burgundy' and 'Bubba', exhibiting an upright form, fast growth, dark green leaves, seedlessness, and crisped corollas with a distinctive red/purple color, achieved through specific propagation methods using semi-hardwood cuttings in a controlled environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Chilopsis linearis cultivars are used, then they can be grown in arid conditions, but they lack the combination of desirable traits including upright growth form, consistent blooming throughout warm season, fast growth rate, dark green leaves, seedlessness, and distinctive red/purple flower color
Solution Approach 1:
The patent combines multiple desirable traits from different parent plants into a single cultivar through controlled cross-breeding. The 'Sweet Bubba' cultivar merges the upright growth form and fast growth rate from one parent with the distinctive red/purple flower color and seedlessness from another parent, creating a plant that exhibits all six desirable characteristics simultaneously rather than requiring separate plants for each trait.
2Productivity
If Chilopsis linearis 'Sweet Bubba' is propagated using semi-hardwood cuttings in controlled environment, then rooting is complete within 4 weeks, but requires specific propagation conditions including fog propagation house and temperature control
Solution Approach 1:
The patent applies preliminary action by preparing semi-hardwood cuttings with specific preprocessing steps before propagation. The cuttings are treated with rooting hormone and placed in a controlled fog propagation environment with predetermined temperature and humidity conditions, allowing rooting to complete rapidly within 4 weeks. This preliminary preparation of cuttings and propagation conditions enables fast propagation while managing the complexity through standardized procedures.

AI summary
A new and distinct Chilopsis linearis tree named Sweet Bubba is characterized by an upright form, fast growth, dark green leaves and having flowers with crisped corollas with a distinctive red/purple color (70A, R.H.S. color chart) and blooming throughout the warm season (locally May-October). No seed production has been noted, beneficial for more flowering and less trash in the landscape.
