Agastache Royal Raspberry Cultivar Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct Agastache hyssop plant cultivar that exhibits a unique combination of traits such as a medium-sized, dense, mounded habit, large rosy-purple flowers, long bloom time, and burgundy-colored calyxes, which are not found in existing varieties.
Innovation Solution
The development of the Agastache 'Royal Raspberry' cultivar, resulting from a single seedling selection and asexually propagated using traditional shoot tip and stem cutting procedures, which maintains its characteristics across generations and is resistant to certain environmental variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional Agastache varieties are used, then they have established growth habits and flower colors, but they lack the unique combination of medium-sized dense mounded habit, large rosy-purple flowers, long bloom time, and burgundy-colored calyxes
Solution Approach 1:
The patent segments the Agastache breeding program by selecting a single exceptional seedling (15-12-38) from a self-pollination of parent 14-8-1, isolating and propagating only this specific plant that exhibits the desired unique combination of traits including medium-sized dense mounded habit, large rosy-purple flowers, long bloom time, and burgundy-colored calyxes
Solution Approach 2:
The patent changes multiple plant parameters simultaneously through selective breeding: flower color (rosy-purple), plant habit (medium-sized dense mounded), bloom duration (extended), and calyx color (burgundy), creating a cultivar that exceeds parent 14-8-1 in these specific parameters
2Reliability
If Agastache plants are propagated asexually using traditional shoot tip and stem cutting procedures, then plants identical to the original are produced, but the propagation process requires multiple generations and time
Solution Approach 1:
The patent employs self-service propagation where the selected seedling 15-12-38 propagates itself through asexual means (shoot tips and stem cuttings) to produce identical clones, eliminating the need for continuous human intervention in the propagation process while maintaining genetic fidelity
Solution Approach 2:
The patent performs preliminary selection and isolation of the exceptional seedling 15-12-38 before mass propagation, ensuring that only plants with the desired unique traits are propagated, thereby preventing time loss from propagating unwanted variations
3Adaptability or versatility
If Agastache plants are grown in different environmental conditions, then phenotype may vary slightly, but the genotype remains unchanged
Solution Approach 1:
The patent creates genetic copies through asexual propagation of seedling 15-12-38, producing multiple identical plants with the same genotype that will express consistent traits across different environments, allowing phenotype variation without genetic change
4Productivity
If the parent plant 14-8-1 is used directly, then it has established characteristics, but it is shorter and more mounded with lighter lavender-pink flowers compared to the new cultivar
Solution Approach 1:
The patent changes specific parameters of the parent plant 14-8-1 through selective breeding to produce cultivar 15-12-38 with enlarged flowers (from typical size to large), intensified color (from lavender-pink to rosy-purple), and modified habit (from short and mounded to medium-sized and dense), while maintaining the Agastache genus characteristics

AI summary
A new and unique cultivar of hyssop, Agastache plant named ‘Royal Raspberry’ with medium-sized, dense, mounded, well-branched habit and spring foliage color with burgundy cast. The large flowers of rosy-purple coloration begin in early summer and cover the top two-thirds of the plant. The effective flowering season is extended with burgundy-colored calyxes in densely branched panicles. The new plant is useful in the landscape and as a cut flower.
