Milkweed and hares

Hey y'all. So I'm wanting to plant milkweed to encourage the monarch population in an area. The thing is, I don't want to upset the wild hares in that area, and read that rabbits will get sick from eating milkweeds. I know rabbits and hares are different, and there are different kinds of milkweeds. Is there a strain of milkweed that hares can eat? If not, is there a way to set up the milkweed on an elevated platform or with a short fence around it to prevent the hares from getting hurt? Any help is useful, thank you.

Edit: I was reading through forums and found that one said that bunnies don't like catnip. Would this work on hares? If so, could I surround the milkweed with catnip to discourage the hares from eating the milkweeds?

Don't worry. The wild hares will know what to eat and not eat.

Agreed. I got plenty of milkweed and plenty of wild bunnies

I agree as well that there's no need to worry about the bunnies/hares.  I have plenty of milkweed and plenty of bunnies.  

I will suggest though that you plant common milkweed and then raise it not just for monarchs but as a wonderful perennial food for yourself as well.  I've got several patches well established now that provided a steady supply of produce over many months this year.  Once established you can harvest the young shoots.  Then later in the season the flower buds, followed by the flowers themselves, and finally the immature pods.  This is a vegetable that needs to be cooked, but it's good stuff, perennial, and abundant!  My harvesting it doesn't seem to have any effect on it's usefulness for monarchs either since they are eating the mature leaves I don't eat, not to mention the fact that I can't keep up with eating all it produces anyway.
