Laburnum in "L. anagyroides" and long in "L. alpinum". They have yellow pea-flowers in pendulous leafless racemes long in spring, which makes them very popular garden trees.

The concept was first introduced by Katharina Rutschky in her 1977 work "Schwarze Pädagogik. Quellen zur Naturgeschichte der bürgerlichen Erziehung". The psychologist Alice Miller used the concept to describe child-raising approaches that, she believed, damage a child's emotional development. Miller claims that this alleged emotional damage promotes adult behavior harmful to individuals.
