Astilbe Verssalmon Cultivar Compact Habit and Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Astilbe cultivars lack compact, strong plant habit and freely flowering characteristics with attractive foliage and flower coloration, particularly in terms of plant height and flowering habit compared to 'Federsee' cultivar.
Innovation Solution
The development of a new Astilbe cultivar 'Verssalmon' resulting from a cross-pollination between an unnamed Astilbe arendsii and Astilbe japonica seedling selection, exhibiting a compact, upright growth habit, strong and healthy foliage, and light salmon pink-colored flowers, which are more freely flowering and compact than the parent selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Astilbe cultivars are used, then they have established foliage and flower coloration, but they lack compact plant habit and freely flowering characteristics
Solution Approach 1:
The patent applies parameter changes by crossing two different Astilbe species (A. arendsii and A. japonica) to alter the genetic parameters of the offspring, resulting in a new cultivar with modified plant height, compactness, and flowering characteristics that differ from both parent selections
2Force
If Astilbe arendsii is used as seed parent, then it provides foliage characteristics, but the offspring lack compact growth and abundant flowering
Solution Approach 1:
The patent merges the genetic material of Astilbe arendsii (providing strong foliage) and Astilbe japonica (providing compact growth and flowering habits) through cross-pollination, combining the beneficial traits of both parent plants into a single hybrid cultivar
