While the culinary uses for the plant are limited due to it being known to cause nausea stomach cramps and headaches in large portions it is at times used in France as a form of "sorrel soup". The plant is also commonly used for study due to its unique genetic structure. Due to their complex chromosomal makeup their sex is determined by the ratio of x and y chromosomes.
