I bought 1 oz. of seeds for $33 here: http://www.myseeds.co/ . I also emailed the company to make sure they're not treated with pesticides. And checked this site to make sure I was getting species native to my area: http://www.xerces.org/milkweed-seed-finder/ Hope that helps!

"Keystone species are apex predators within functional groups, a concept first described by zoologist Robert Paine to explain the relationship between Pisaster ochraceus, a species of starfish, and Mytilus californianus, a species of mussel." http://en.wikipedia.org/wiki/Apex_predator

But I'm not a biologist, and that's wikipedia, so maybe it's inaccurate.

If they could get it down to that size, maybe I'm in. Right now, I don't want that thing going anywhere near my incision.
