Name: LariAnn Garner south Florida, USA When in doubt, do the cross!
This plant is not a Philodendron - it is my hybrid of Alocasia odora and Alocasia cuprea (Alocasia x cupredora), done years ago. It ended up at that garden, most likely, because Fairchild Tropical Garden shared it with them. Fairchild is the first garden that got one of these. See my page below for more info.
