I had one have it -- must have bought it like that -- funny thing is that everyone commented on how pretty that hosta was.... so finally when fall came I dug it up and thru it on the burning pile
... then I bleached every thing and even poured bleach into the grouond where it lived. (just in case)... then I stuck a garden ornament on that spot (big old rusty milk can) and it's been there ever since. No more sign of it in my garden.
