Penstemon Cha Cha Cherry Compact Upright Growth Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Penstemon cultivars lack a compact, upright growth habit with dense, medium-sized red flowers and long flowering time, as well as attractive foliage and seed heads, which are not fully met by current varieties like Penstemon Arabesque™ Red and Penstemon ‘Garnet’.
Innovation Solution
A new Penstemon cultivar, ‘Cha Cha Cherry’, with a compact, upright habit, medium-sized red flowers in dense clusters, long bloom time, attractive deep purple seed heads, and deep green foliage, achieved through controlled breeding and asexual propagation, ensuring consistent progeny characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Penstemon cultivars like Penstemon Arabesque™ Red are used, then they have red flowers, but they lack compact upright habit and have fewer flowers with white eye
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants to modify specific characteristics including growth habit (compact, upright), flower density (dense clusters), flower size (medium), and flower color (red without white eye). This systematic alteration of plant parameters through controlled breeding resolves the contradiction between achieving compact shape and increasing flower quantity.
2Shape
If existing Penstemon cultivars like Penstemon 'Garnet' are used, then they have red flowers, but they have floppy habit and fewer flowers
Solution Approach 1:
The patent employs parameter changes through controlled breeding to simultaneously improve multiple traits: establishing upright growth habit while increasing flower number to dense clusters, modifying flower size to medium, and ensuring red coloration without white eye. This multi-parameter optimization resolves the contradiction between uprightness and flower quantity.
3Stability of the object's composition
If asexual propagation is used to reproduce Penstemon 'Cha Cha Cherry', then consistent characteristics are maintained, but propagation complexity increases
Solution Approach 1:
The patent applies the copying principle through asexual propagation methods including cuttings and micropropagation. These techniques create genetically identical copies of the parent plant, ensuring that all progeny exhibit the same desirable characteristics (compact upright habit, dense red flowers, long bloom time, attractive foliage and seed heads). This resolves the contradiction by maintaining compositional stability through biological copying rather than sexual reproduction.
