Everything you ever wanted to know about the species (yes, the species)
Philodendron xanadu, and more:

Unless your a taxonomy nut like me, you'll probably not want to read it all, so I'll summarize:
Philodendron xanadu is a species, not a cultivar, not a variety, not a sport, not any kind of mutation. It is native to Brazil. There are no native philodendrons in Australia, contrary to several website informations. The plant patent given for
P. 'Xanadu' is being re examined. The link I gave above shows mostly adult foliage forms of the species, and one juvenile form. As with many houseplants, it is the juvenile form that is usually distributed in commerce, and it is this form that KAMasud shows in photo #1.
