Cha Cha Lavender Penstemon Compact Growth and Dense Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a compact, upright Penstemon cultivar with medium size, lavender purple flowers in dense clusters, long bloom time, and excellent vigor, which is suitable for sunny borders and can be reliably propagated through asexual methods.
Innovation Solution
The development of the 'Cha Cha Lavender' Penstemon cultivar, characterized by its compact growth habit, medium size lavender purple flowers in dense clusters, long bloom time, and attractive foliage, achieved through controlled breeding and propagated via cuttings and micropropagation, ensuring consistent characteristics across progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If Penstemon cultivars are bred for larger flowers, then flower size increases, but the number of flowers per cluster decreases and compactness is lost
Solution Approach 1:
The patent applies local quality by creating a cultivar with differentiated flower characteristics - medium-sized lavender purple flowers with distinctive white eyes and bee tracks. Each flower maintains moderate size (not overly large) while possessing unique visual features, allowing dense clustering without sacrificing individual flower appeal. This resolves the contradiction by optimizing local flower properties rather than maximizing overall size.
2Duration of action of moving object
If Penstemon cultivars are bred for longer bloom time, then flowering duration increases, but vigor and disease resistance may be compromised
Solution Approach 1:
The patent employs preliminary action through controlled breeding programs that pre-select for both extended bloom time and robust health characteristics. The cultivar was developed through systematic selection of parent plants exhibiting both long flowering duration and strong vigor, ensuring these traits are inherited together. This resolves the contradiction by establishing both desirable traits in advance through deliberate breeding rather than accepting trade-offs.
3Volume of moving object
If Penstemon cultivars are bred for compact growth habit, then plant size decreases, but flowering capacity and vigor may be reduced
Solution Approach 1:
The patent applies dimensionality change by redirecting the plant's growth from vertical expansion to horizontal flowering density. The 'Cha Cha Lavender' cultivar achieves compact stature (40 cm wide, 68 cm high) while compensating through increased flower cluster density and multiple crowns from the base. This resolves the contradiction by changing the growth dimension from height/volume to lateral flowering capacity.
