@adfbf87b yes, we’ve tried harvesting. The roots have good taste but are a bit too small and fibrous for use as grated wasabi. The leaves, stalks and flowers can be used in pickles, tempura, etc in the early spring before they mature and the bugs go after them. 

 @efeed78f thanks! This gives me ideas if I am able to keep it alive through the winter. ❤️
