ABPP Geranium Cultivar Compact Habit and Deep Pink Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Geranium cultivars lack a compact, intense deep pink flowering variety with smaller leaf size and shorter leaf and flower stems, suitable for dense habit and specific cultural requirements.
Innovation Solution
A new cultivar, 'ABPP', derived from Geranium ×cantabrigiense 'Westray', exhibiting a dense habit, intense deep pink flowers borne on short stems, smaller leaves, and stable propagation through stem cuttings, root cuttings, and division, suitable for USDA Zone 6.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If Geranium cultivars are bred for larger leaf size and longer stems, then the plant appears more vigorous and robust, but the plant loses compact habit and becomes less suitable for dense planting and container cultivation
Solution Approach 1:
The invention applies parameter changes by selecting for specific morphological parameters: reduced petiole length (4 cm vs 10 cm in parent), reduced peduncle length (3 cm vs 20 cm in parent), and reduced leaf size (approximately half the length and width of parent). These parameter changes collectively produce the compact habit desired for container and dense planting applications.
2Shape
If Geranium cultivars produce larger flowers on longer stems, then flower display is more prominent, but the plant becomes less dense and requires more space
Solution Approach 1:
The invention changes the peduncle length parameter from 20 cm in the parent variety to 3 cm in the new cultivar. This dramatic reduction in flower stem length causes flowers to be borne closer to the foliage canopy, creating a dense, mounded habit that is ideal for container cultivation and dense planting schemes.
3Quantity of substance
If Geranium cultivars have larger leaves, then the plant appears more substantial and provides better ground cover, but the plant loses profuseness of foliage and becomes less suitable for container growth
Solution Approach 1:
The invention applies parameter changes to leaf dimensions, producing leaves that are approximately half the length and width of the parent variety. Combined with increased leaf number, this creates profuse, fine-textured foliage that fills containers effectively while maintaining a compact overall plant form.
