My opinion is if its free and it fell off the cart its mine., LOL. Once when we lived in California someone had decided that they did not want this HUGE about 4 ft tall 2 foot wide Jade Plant, dug it up and put it out for the trashman by the curb. I took that sucker home, potted it and grew it for 7 years. When we left CA for FL I could not bring any of my plants, Florida would not allow them in over the state line due to the California Brown Snail quarantine. So I left it for the next tenants along with a bunch of cacti and succulents, bromeliads and a big Dracaena. I think in So Cal Jade Plants in the yard are common, not in my part of Florida though. I also share things with people from my place, I have epiphytes like Anthurium scandens that you can take a couple snips off of and start a whole new basket tout suite.
