A trip through America and Mexico in 1965 was a turning point. The lush vegetation and bright colours of Mexico made a deep impression on Ferdi and she threw herself back into the welding business. Now, she created human-sized constructions which she covered with silk and artificial fur. This is how her famous Hortisculptures came into being: flower and plant-like forms with explicitly present sexual organs, creating sensual hybrids between plants and animals.
