RE: just planted the hostas
My initial concern was whether or not it would be considered a invasive plant. It varies some what from state to state, so I would check into that, your county Extension Office would be the place to call. My state does not consider it invasive. The next challenge would be establishment, I would think a deer would pull it up before it had a root system and just eat the plant, bulb and all. They could be protected though until that wasn't a concern, with tree tops placed over them. Lastly, they will not tolerate frost and will not be of any benefit to nothing or no one as soon as the first frost arrives. JMHO.....not trying to discourage or offend anyone.
