Heuchera IFHESBS Plant Breeding Compact Habit and Light Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Heuchera plants lack compact and high light-tolerant varieties with distinct leaf venation and attractive flower coloration, and they often exhibit variability in garden performance and winter hardiness.
Innovation Solution
A new Heuchera plant, 'IFHESBS', is developed through controlled cross-pollination and asexual reproduction by in vitro meristem culture, exhibiting a compact, densely foliated, and bushy habit with yellow-green leaves becoming yellow, tolerant to high light, and producing light pink flowers, offering improved garden performance and winter hardiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Heuchera varieties are used, then they have basic growth and flowering, but they lack compact habit and high light tolerance
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific morphological parameters (compact habit, leaf size, venation pattern) and physiological parameters (light tolerance, winter hardiness) to create a new cultivar that simultaneously improves both plant shape and light tolerance adaptability
2Shape
If existing Heuchera varieties are used, then they produce flowers, but they lack distinct leaf venation and attractive coloration
Solution Approach 1:
The patent applies local quality by emphasizing specific local characteristics of the leaves - particularly the venation pattern and coloration - while maintaining overall plant compactness. The distinct venation and yellow-green to yellow color changes are localized features that enhance aesthetic quality without affecting overall plant structure
3Reliability
If existing Heuchera varieties are used, then they grow in gardens, but they show variability in performance and winter hardiness
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination and selective breeding in advance to pre-establish the genetic traits for winter hardiness and consistent garden performance before field testing. The multi-year evaluation process (2016-2021) represents preliminary verification of reliability under various conditions including winter temperatures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new Heuchera plant 'IFHESBS' demonstrates stable and true-to-type characteristics, including compact growth, high light tolerance, and good garden performance, distinguishing it from its parents and comparable varieties like 'Electra' and 'Red Lightning', with enhanced leaf venation and winter hardiness, making it suitable for USDA Hardiness Zones 3 through 9.
Implementation Method 1
Asexual reproduction of the new Heuchera plant by in vitro meristem culture in a controlled environment in Heerhugowaard, The Netherlands since September, 2016 has shown that the unique features of this new Heuchera plant are stable and reproduced true to type in successive generations.

AI summary
A new and distinct cultivar of Heuchera plant named ‘IFHESBS’, characterized by its compact and uniformly mounded plant habit; moderately vigorous to vigorous growth habit and relatively rapid growth rate; densely foliated and bushy appearance; leaves that are initially yellow green in color with distinct venation becoming yellow with development; leaves that are relatively tolerant to high light conditions; numerous inflorescences with light pink-colored flowers; and good garden performance and winter hardiness.
