Yay! I recognize some of these!! According to my aunt, the one with the big pink leaves surrounding the very small yellow petals is called "Lantana." She tried to grow it in Ohio for a long time, but it kept dying. When my aunt and uncle visited me in Houston she was jealous/dismayed because in the Houston climate it grows in big bushes like that above as a weed.I don't know what the last one (the orange) is, but it was everywhere in Thailand. I liked it and I would like to know what it is if you know because I think it would grow well in Houston/NOLA.
