Hydrangea Paniculata B10 Compact Habit and Conical Inflorescence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Hydrangea paniculata that exhibits a compact and short growth habit with unique inflorescence and foliage characteristics, distinct from existing cultivars like 'B2' and 'ILVOBO', which are similar but differ in flower sepals, inflorescence shape, and plant height.
Innovation Solution
The new cultivar 'B10' features a broadly obovate and upright growth habit, compact and short plant habit, conical white inflorescences that turn pink in autumn, and dark green sturdy foliage, achieved through asexual propagation by stem cuttings, which are stable and reproduced true to type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If asexual propagation by stem cuttings is used, then the characteristics of the new cultivar are stable and reproduced true to type, but the time required for propagation increases
Solution Approach 1:
The patent performs preliminary selection and identification of the unique cultivar characteristics before formal propagation. The cultivar was discovered and characterized in August 2019, with propagation attempted in September 2019, allowing preliminary assessment of growth habits, inflorescence characteristics, and foliage properties before establishing it as a formal cultivar. This preliminary characterization ensures stability is verified before widespread propagation begins.
2Adaptability or versatility
If the plant habit is made compact and short, then the plant is more suitable for landscape and potted use, but the growth rate may be reduced
Solution Approach 1:
The patent describes a cultivar with specific parameter changes that achieve compact habit while maintaining growth vigor. The plant reaches 58 cm in height with a 70 cm spread, creating a compact form suitable for containers and landscapes. The cultivar exhibits moderate to high growth rate despite the compact habit, achieved through selective breeding that modified growth parameters while maintaining adaptability to various planting situations including USDA Zones 5 to 9.
3Shape
If the inflorescences are made conical and white turning pink in autumn, then the visual appeal is enhanced, but the differentiation from similar cultivars requires precise characterization
Solution Approach 1:
The patent applies local quality by providing detailed, site-specific characterization of the inflorescence traits. The inflorescences are described as conical in shape with specific color progression (white to pink in autumn), and these local characteristics are precisely documented to differentiate 'B10' from similar cultivars like 'B2' and 'ILVOBO'. The patent notes that 'B10' has conical inflorescences rather than the rounder shapes of comparable cultivars, and the color change pattern is specifically recorded as white to pink in autumn, providing precise local quality differentiation.
