Like all surrealists, Max Ernst also introduced chance elements into his work. For this purpose he made use of such techniques as tracing, stippling, grattage (scratching and scraping) and frottage (rubbing). Vegetation is one of the earliest examples of his work in which this can be seen. The organic, playfully applied paint contrasts sometimes rigid, sometimes loose graphic quality of the scratched lines. The evocative effect of the image and the great freedom with which it was executed give the panel its expressive power. In Belgium it was mainly Frits van den Berghe who was influenced by the new style seen in Max Ernsts work.
