I use to get some really different plants at the grocery store. I think after the depression they stopped putting them in the grocery stores. People were too broke to buy plants. They had a hard enough time just buying food.
Both my HD and Lowes get a small selection of different plants and you have to be there when the order comes in to catch the few that are different. The one or two different ones I think are accidents that slip in to the order. I have seen 20 photos and corn plants and one or two of something different. You know they are mistakes or maybe an order that got mixed in by mistake with the usual order.
