Hydrangea Bokomapishad Compact Habit and Color Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea paniculata cultivars lack compact and dense plant habits with unique inflorescence shapes and colors, limiting their landscape appeal and diversity.
Innovation Solution
The development of the 'Bokomapishad' cultivar, a compact perennial shrub with dense paniculate inflorescences featuring white and deep pink sterile flowers, ovate to conical shaped inflorescences, and a stable propagation method through softwood stem cuttings, which reproduces true to type in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Hydrangea paniculata cultivars are used, then plant growth is maintained, but plant habit is not compact and inflorescence shapes are not unique
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific morphological parameters (compact plant habit, dense paniculate inflorescences, ovate to conical shape) through controlled breeding and asexual propagation, transforming the plant from conventional growth patterns to a distinct cultivar with unique shape parameters
2Reliability
If asexual propagation by softwood stem cuttings is used, then true-to-type reproduction is achieved, but propagation time is required
Solution Approach 1:
The patent employs copying through asexual propagation by softwood stem cuttings, creating genetic copies of the parent plant that reproduce true-to-type characteristics. This copying method preserves the unique morphological traits (compact habit, inflorescence shape, flower color) without the need for sexual reproduction and subsequent genetic variation
3Ease of manufacture
If sterile flowers are white in color and mature to deep pink, then unique color change is achieved, but color development time is extended
Solution Approach 1:
The patent utilizes color changes by selecting plants with sterile flowers that transition from white to deep pink maturing. This color transformation is a key distinguishing characteristic of the cultivar, achieved through genetic selection and stabilized through asexual propagation, creating a unique visual display that develops over the flowering period

AI summary
A new cultivar of Hydrangea paniculata plant named ‘Bokomapishad’ that is characterized by its compact plant shape, its strong and healthy foliage including while in bloom, its sterile flowers that are white in color and mature to a deep pink color, its ovate to conical shaped inflorescences with obtuse tips, and its inflorescences that consist of both fertile and sterile flowers with the fertile flowers mostly hidden by sterile flowers.
