Wow, I agree with everyone else ... gorgeous Philo's! I just grow the small house plant variety of Philodendron; although at our other house that we currently rent out there are a few P. bipinnatifidum (Tree Philodendron):
Tree Philodendron (Thaumatophyllum bipinnatifidum) planted in the ground. They were there when we bought the property in 1975 and I think those are about the only Philo's that do well here in this part of Florida. They've been knocked down by freezes over the years but always come back.
