Well, I'm glad I wasn't the only one who thought the Abbott's Sphinx was scary. I was seriously wondering if it was some kind of harbinger of death and I should watch Grandma carefully!
Let's see...plants. We grow the Coral Bean at MOSI. I don't tend to notice it too much because we have so many other plants, but it's a good native and has those kind of flowers loved by Sulphurs and hummingbirds.
Like Ann, I grow the Salvia 'Black and Blue' but mine comes back every year and reseeds itself in nearby locations. It's a little "sprawly" but that's probably my fault. I don't think the butterflies go for Salvias as much as people think they do. This is the first year I've really seen them use 'Mystic Spires' and it's been surprising. My butterflies tend to prefer flat, composite type flowers.
Wild Cherry. I call it Black Cherry, but it's still P. serotina. Bought one several years ago from the FL Native Plant Society. Best host plant ever! I've had: Red Spotted Purple, Tiger Swallowtails (once), Furcula Moths, Nason's Slug Moth, Saddleback Caterpillar Moths, and my Unicorn Caterpillar Moths. And a few things BAMONA couldn't ID. And probably a few I've forgotten over the years. It also grows really fast if that's what you're looking for. Mine started out barely taller than me about 8-9 years ago and now it's about 40 feet high. It's as tall as my oak trees. No lie.
A. tuberosa is a good native to use instead of the Tropical Milkweed, if you worry about things like that. I had some years ago, but I change things pretty frequently. I bought some seeds and just threw them on the ground using my patented "Toss and Stomp" method. (Toss seeds on ground, stomp on them for good soil contact.) I don't know why anyone buys milkweed plants when seeds are so easy to grow. I would just say if you have the Tropical Milkweed, the Monarchs tend to favor it heavily. So A. tuberosa should probably be either grown away from Tropical Milkweed, or used as a backup food source. I did have them lay eggs on it, but nothing like the constant attacks on the Tropical.
Sulphur & Bee - 
. Made a small arbor/trellis thingee(my neighbor calls it the "funeral pyre") and let it grow. I keep all the new growth at the bottom of the main vines stripped up until about the first 3 feet so there's no chance of them rooting.
Maypop (P. incarnata) is hard to get rid of - as the dumpsite proves.
Well I can tell you that here in this area sometimes incarnata returns and sometimes it doesn't, depending on the type of winter we get and its location in the garden. I haven't had any trouble so far
