I have a hard clay soil, and for years it hardly grew at all. Then I started noticing a few young sprouts here and there a few meters away from the main bunch.
I transplanted the main plant into a corner of a raised bed several years ago and it has very gradually gotten larger, but so far no distant sprouts. It has not been really obnoxious, but I suspect hard to get rid of once established.
I planted it 20 years ago just for fun, and so far have never even harvested any. May dig some roots this fall.
