Perla34396 Hydrangea Cultivar for Single-Stem Cut Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea macrophylla cultivars are unsuitable for growing as single-stemmed plants due to dense branching and soft-textured, smaller inflorescences, limiting their use in cut flower production.
Innovation Solution
Development of the 'Perla34396' cultivar with sparse branching and firm, long-lasting, purplish pink to red sterile flowers, suitable for single-stemmed growth and enhanced inflorescence size and texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Hydrangea macrophylla cultivars are used, then the plant grows with dense branching, but this makes the plant unsuitable for single-stemmed cut flower production
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific branching density parameters. The cultivar 'Perla34396' was selected from seedlings with sparse branching characteristics, and this parameter was maintained through asexual propagation by softwood stem cuttings, resulting in a stable cultivar with the desired single-stemmed growth habit suitable for cut flower production
2Reliability
If existing Hydrangea macrophylla cultivars are used, then the inflorescences are smaller and softer, but this reduces their durability and visual appeal for cut flowers
Solution Approach 1:
The patent applies parameter changes by selecting seedlings with specific inflorescence characteristics including larger size and firmer texture. The sterile flowers of 'Perla34396' are described as firm in texture and long lasting, changing color from purplish pink to red with green centers, which were selected and maintained through controlled crossing and asexual propagation

AI summary
A new cultivar of Hydrangea macrophylla plant named ‘Perla34396’ that is characterized by its sparse branching that makes the plant suitable to grow single stemmed plants for the use of cut flowers, its large inflorescences, its inflorescences and sterile flowers that are very firm in texture and long lasting, and its sterile flowers that are purplish pink and change to red with green centers when they fade.
