When my mother was in a nursing home in La Mesa, CA, there were spider lilies growing up against a stone wall, adjacent to a blacktopped parking lot. The only shade they had was from the wall at certain times of the day. I often wondered what they were, and should have gone out and "rescued" a small section for my yard. Alas, I didn't.
Wow, I bet they experienced a lot of collected heat from the wall and blacktop! They must be pretty tough plants to thrive in a situation like that. I have several "should have" stories like that in my gardening past, unfortunately. One involves a great aunt who had a gorgeous garden. She was always giving me cuttings and bulbs and starts of things. After she passed away, I learned that the daughter who inherited her house tore out many of the plants and planted the areas back to grass. Oh, how I wish I'd had the opportunity to go dig up a bunch of those plants before they were discarded! It would have meant so much to me to have them. I planted "surprise lilies" in her memory, as she was the one who jokingly introduced me to their nickname, "Naked Ladies."
