I'll probably order one.

Monarch Watch sells garden "waystation kits" to encourage Monarch butterflies. Growing up in California, that's the butterfly I think of.

I tried planting milkweed on our hill a couple years back and it didn't take; the soil may have been too well-drained for it to root properly. (I probably should have sprouted it inside first, too.) I think the top of our yard will work, however. I don't think I'll apply for certification - it's basically a sign you can post in your garden.
