UPDATE! This actually turned out to be a plain ol selloum, but with ruffled and lacy leaves. It seems like there is a lot of variation with these!
I saw this oddity at a local target a couple of weeks ago, and have been thinking about it ever since. It has wavy, slightly lobed leaves as opposed to the usual deeply lobed ones, is a slightly darker, bluer color, and has bright white margins. Also, it's not as glossy as other selloums and if you look closely you can see each and every white vein.
After doing a bit of research it does bear a resemblance to philodendron 'evansii', a hybrid between p. bipinnatifidum and p. speciosum made in the 40's and used mostly in the 60's and 70's in South Floridian foundation plantings. From what I've seen it has even bigger leaves that either of its parents, is pretty hard to find, and is cold tolerant to zone 9a. I'm sure that some of you guys have seen it before so what do you think? It may even be a new accidental hybrid or selection for all I know, but ideally it would just be an unusual form of good ol' cold tolerant philodendron bipinnatifidum. I've placed it at the base of my evergreen yellow anise, which should provide some protection in winter just in case its not too cold tolerant. I suppose Ill definitely have a better idea when it flowers, since the spathe of 'evansii' is bright salmon pink! Here's a view of the whole plant.
Any help would be great!
