I never have! But I am going to sow some and if it thrives I will try it.I haven't found leaves yet that match the pictures. But this seems likely, with different local varieties. We have something called a sorrel here, it has tangy leaves. We used to call it sourgrass when I was a kid. I will find some and dig it to see if it has these tubers. But hey, has no one but me actually tasted this, either the leaves or the tubers? And why no curiosity, if not?![]()
