Caladium Carousel Cultivar Leaf Coloration and Growth Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Caladium plant cultivars with uniform plant habit, exceptional container and garden performance, and unique leaf coloration that can tolerate various environmental conditions and cultural practices.
Innovation Solution
The development of the Caladium plant cultivar 'Carousel', resulting from a cross-pollination between Caladium×hortulanum 'White Christmas' and 'John Peed', which exhibits intermediate height, vigorous growth, fancy-type leaves with specific coloration, and improved landscape performance, including sun tolerance, through asexual reproduction by 'chipping' tubers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cross-pollination is performed to create new Caladium cultivars with unique leaf coloration, then leaf color diversity is improved, but plant habit uniformity may deteriorate
Solution Approach 1:
The patent applies local quality by focusing the unique coloration traits specifically on the leaf blades while maintaining uniform plant habit characteristics. The 'Carousel' cultivar exhibits distinctive white interveinal panels with pink blush on the leaf blades, while the overall plant structure, growth pattern, and habit remain consistent and uniform, resolving the contradiction between color uniqueness and habit uniformity.
2Productivity
If asexual reproduction by tuber chipping is used, then propagation speed is improved, but genetic stability may deteriorate
Solution Approach 1:
The patent employs tuber chipping as a form of copying where each tuber segment containing an axillary bud serves as a clone of the parent plant. This asexual reproduction method produces genetically identical copies that rapidly propagate the cultivar while maintaining genetic stability, as the tubers naturally contain the complete genetic information needed to reproduce the plant true-to-type.
3Productivity
If vigorous growth habit is selected, then growth rate is improved, but plant compactness may deteriorate
Solution Approach 1:
The patent applies dynamics by allowing the plant to exhibit vigorous growth rates while maintaining a compact, mounded habit through balanced development. The 'Carousel' cultivar demonstrates dynamic growth where multiple shoots emerge from tubers and develop into a dense, upright clump that is both rapidly growing and space-efficient, resolving the contradiction between growth speed and compactness.

AI summary
A new and distinct cultivar of Caladium plant named ‘Carousel’, characterized by its intermediate height; upright and uniform plant habit; vigorous growth habit and very rapid growth rate; fancy-type leaves with white-colored interveinal panels that are often and randomly blushed with light pink, red-colored venation and dark green-colored margins; and good landscape performance and sun tolerance.
