Hydrangea Pinky Ring Picotee Flower and Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea cultivars lack a compact-upright growth habit with a double-type, picotee flower color pattern, which limits their aesthetic and horticultural appeal.
Innovation Solution
A new Hydrangea macrophylla cultivar, 'Pinky Ring', developed through controlled breeding, exhibits double-type, modified lacecap inflorescences with a light pink picotee pattern, dark green foliage, and a moderately vigorous, compact-upright growth habit, achieved through cross-pollination between proprietary breeding selections KD10 and K16.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Hydrangea cultivars are used, then they have simple flower structures and larger growth size, but they lack the picotee color pattern and compact-upright growth habit
Solution Approach 1:
The patent applies local quality by creating a picotee color pattern where the flower edges have a distinct darker pink border contrasting with the lighter pink center. This localized color differentiation transforms the simple flower structure into a more complex and visually appealing double-type flower with sterile florets arranged in a modified lacecap pattern, resolving the contradiction between simple structure and desired complexity
Solution Approach 2:
The patent employs nesting by arranging sterile florets in a compact-upright configuration where smaller florets are nested within a larger inflorescence structure. The double-type flowers contain multiple layers of petals and stamens nested within each other, creating a dense, compact appearance that maintains a smaller overall growth size while achieving complex floral structures
2Ease of manufacture
If conventional Hydrangea cultivars are used, then they have simpler flower patterns, but they lack the distinctive picotee color pattern
Solution Approach 1:
The patent applies parameter changes by modifying the color parameters of the flowers to create the picotee pattern. The breeding process altered the pigment concentration and distribution, resulting in flowers with a light pink base color and a darker pink picotee border. This parameter change transforms the simple solid-color flowers of conventional cultivars into the distinctive two-toned picotee pattern without requiring complex structural modifications
3Length of moving object
If conventional Hydrangea cultivars are used, then they have larger growth habit, but they lack the compact-upright form
Solution Approach 1:
The patent applies dynamics by creating a compact-upright growth habit that optimizes the plant's vertical space utilization. The cultivar exhibits a dynamic balance between moderate vigor and compact form, allowing the plant to maintain an upright posture while limiting excessive height growth. This dynamic growth pattern enhances ornamental value by creating a neat, tidy appearance suitable for container gardening and small spaces, resolving the contradiction between plant size and aesthetic appeal
