Ken - I think the difference in our experiences is less north/south or urban/rural, but more about indoors (year-round) vs outdoor plant growing. I confess to not having experience with or knowing about growing FLF's outdoors and would always defer to your expertise in that area. However, I do have lots of experience with FLF's kept indoors year-round. For sure, that is outside their "normal" or native habitat so their indoor requirements are quite different than those grown outdoors or in greenhouses.
I try to limit my replies to plants that are grown indoors in more northern climates.
Nearly all "houseplants" are tropical or semi-tropical in origin otherwise they would not survive our year-round warm indoor temps up north. What makes them "houseplants" is that they are kept indoors year-round.
