I bought this out of curiosity and to answer your question: it is not a Philodendron but a Homalomena cultivar. Nontheless, it is a very striking and purdy plant. At first glance, many aroid collectors would be tricked to think it's something like Philodendron gloriosum or pastazanum but nope, it's Homalomena. I like it a lot regardless and would recommend this to anyone who wants to mess with their horticulturally-enthused friends.
