I would be more then happy to plant some of the swamp milkweed, not sure what it is but if its advantageous Id be glad to do it, and it looks beautiful.
Another issue we have in this area is a decline in honeybee numbers, we don't have near as many as we used to. and talking to bee keepers it is getting harder and harder to maintain healthy hives. but I think a lot of it has to do with some of the potent pesticides that are being used these days. makes one wonder if any of that has anything to do with the decline of Monarchs.

All the really good ideas I've ever had came to me while I was milking a cow.
