Penstemon Cultivar Barpenpeppur Compact Habit and Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new early-flowering Penstemon plants with attractive flower colors that exhibit compact and vigorous growth habits, as existing varieties may lack these desirable traits or have variations in flower color and flowering timing.
Innovation Solution
A new cultivar of Penstemon hartwegii, 'Barpenpeppur', was developed through controlled cross-pollination, characterized by an upright and compact plant habit, vigorous growth, early and free-flowering, long flowering period, and distinct dark red-purple flowers with light pink centers, achieved through asexual reproduction by cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Penstemon varieties are used, then they may have attractive flower colors, but they lack compact and vigorous growth habits or have variations in flowering timing
Solution Approach 1:
The invention applies parameter changes by selecting and combining specific genetic traits from parent plants to achieve a new cultivar with optimized parameters: compact plant habit (improved from sprawling), vigorous growth rate, and consistent early flowering timing. The cross-pollination between Pe-0003 and Pe-0099 resulted in offspring with stabilized genetic parameters that reliably produce compact, vigorous plants with uniform early flowering.
2Loss of time
If early-flowering varieties are selected, then flowering time is improved, but plant compactness and growth vigor may be compromised
Solution Approach 1:
The invention merges desirable traits from two different parent selections (Pe-0003 and Pe-0099) into a single cultivar. The early flowering trait from one parent is combined with compact growth habit and vigorous growth from the other, creating a unified plant that simultaneously exhibits all three desirable characteristics without compromise.
3Productivity
If conventional breeding methods are used, then new varieties can be developed, but the process may not produce stable and true-to-type characteristics in successive generations
Solution Approach 1:
The invention utilizes self-service through asexual reproduction by cuttings, where the plant propagates itself vegetatively to produce clones that are genetically identical to the parent. This method ensures that the compact habit, vigorous growth, and early flowering traits are perfectly replicated in successive generations without the variability introduced by sexual reproduction, achieving both breeding efficiency and trait stability.
