I'm not sure what this is. Is it a crepe myrtle? It seems happy planted up again the west wall of the neighbors' house. It's in full fall color right now, as you can see.
I know what these are called: they're medlars in English and nèfles in French. I've never tasted them but I may well do so this fall. They're not good to eat until they've been touched by frost. Then they are "bletted" and can be eaten raw or cooked. Unless the neighbors or their children come pick them, I'll ask for permission to take some after our first frosts occur.
These red flowers are called mandevilla or dipledenia. They are tropical or sub-tropical in origin, and frost will kill them. The neighbors left 6 or 8 pots of them on their terrace and around the yard. Unless somebody comes to take them away, I'll ask permission to put one or two of them in our greenhouse for the winter. Evidently, you can root cuttings and propagate new plants that way.
