Not really concerned about invasiveness, the winter here would pretty much wipe out any of the little buggers. It's also in a pot, it's a houseplant for me.
The picture in that pdf is insane, though I doubt I will have any problem with invasiveness. Garlic Mustard is our weed big invasive and at least that's tasty.
I just started collecting succulents this summer, I have crassula ovata (Jade) , a bunch of euphorbia trigona (African Milk Tree), Aloe vera, Pilosocereus azurescens, and Myrtillocactus geometrizans. If I ever run into a San Pedro I will definately pick one up (what I mistook the Myrtillocactus for). Right now the highlight of my collection are my yellow-flowered Datura Innoxia, though.
