I had to chuckle about getting plants out of trash cans. I'm in the Keys on vacation and visited a couple nurseries looking for bromeliads, found nothing. Driving back I saw many had yard waste out by the curb and kept my eyes peeled for broms :)
All the dessert roses are so beautiful, there is one I see in Port Orange at a house I drive by that is as tall as the roof, which suprises me since it can get to freezing. One day I'll get a snapshot of it.
