I got this yesterday, I liked the dusty, silver look of the leaves. It came with the name Philodendro Plateado, plateado means silver and from looking at google links it seems to be hastatum "silver" or just P. hastatum.
I'm considering whether to plant it in a pot or put it in the ground where it can climb my rock wall. Right now it is on the terrace and I need to decide before it starts attaching to the column. The other place I could plant it in the ground is under a trio of fish tail palms, it could climb the palms but it would have to compete with a monstera that is also beginning to climb them.
