Delosperma Cultivar With Dense Bloom and Climate Hardiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Delosperma cultivars lack distinct characteristics such as strong reddish-purple petals, low mounded habit, good flower coverage, and tolerance to winter, drought, and heat, which are desirable traits for landscaping and gardening.
Innovation Solution
The development of the Delosperma cultivar 'Electric Slide', which combines unique features like reddish-purple petals, low mounded growth habit, and tolerance to USDA Zone 6 and above, along with good drought and heat tolerance, achieved through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Delosperma cultivars are used, then they have some flowering characteristics, but they lack the combination of strong reddish-purple petals, low mounded habit, good flower coverage, and tolerance to winter, drought, and heat
Solution Approach 1:
The patent combines multiple desirable traits from different parent plants into a single cultivar. The female parent 'PJS01S' contributed fuchsia to reddish raspberry petals and drought/heat tolerance, while the male parent 'John Proffitt' contributed lighter purplish-red petals and winter hardiness. The resulting 'Electric Slide' cultivar merges these characteristics to achieve strong reddish-purple petals, low mounded habit, good flower coverage, and comprehensive tolerance to winter, drought, and heat conditions.
Solution Approach 2:
The patent achieves desired characteristics by changing key parameters of the Delosperma plant through selective breeding. The flower petal color was changed to strong reddish-purple, the growth habit was changed to low and mounded, and the tolerance parameters were adjusted to withstand USDA Zone 6 winters, drought conditions, and heat. These parameter changes were achieved through controlled hybridization and subsequent selection of plants exhibiting the desired trait combinations.
2Shape
If Delosperma cultivars are bred for specific flower colors and habits, then they achieve distinctive appearance, but they may lose tolerance to environmental conditions
Solution Approach 1:
The patent applies preliminary action by selecting parent plants that already possess the desired traits before hybridization. The female parent 'PJS01S' was selected for its fuchsia to reddish raspberry petals and drought/heat tolerance, while the male parent 'John Proffitt' was selected for its lighter purplish-red petals and winter hardiness. By choosing parents with predetermined desirable characteristics, the breeding process increases the likelihood of producing offspring that maintain both aesthetic traits and environmental tolerance.
Solution Approach 2:
The patent employs feedback through systematic evaluation and selection of hybrid offspring. Plants from the hybridization between 'PJS01S' and 'John Proffitt' were grown and evaluated for their expression of desired traits including low mounded habit, reddish-purple flower color, and environmental tolerance. Plants that failed to meet the criteria were eliminated, while those exhibiting the desired combination of shape and winter hardiness were selected for further propagation and development into the final cultivar.

AI summary
A new and distinct cultivar of Delosperma plant named ‘Electric Slide’ is disclosed, characterized by abundant strong reddish-purplish petals nearly covering the plant. Plants have a low, mounding habit, and are tolerant to at least USDA zone 6. The new plant is useful for its. bright flowers and low habit in the landscape or as a container plant.
