Philodendron 'Pluto' is sometimes better known as a reverted Philodendron 'Carmel Marble' but that actually does a disservice to this gorgeous plant that has been a popular hybrid for at least 25 years. It is prized for the beautiful serrated shape of the leaves as well as it's glossy, darker foliage.
Typical philodendron care applies - medium to bright light, allow to approach dry between waterings, added humidity is appreciated but not strictly necessary.
