Guide
The species-level account. Cultivar pages build on this and say where they differ.
Philodendron radiatum is a climbing aroid from the warm, humid forests of southeastern Mexico, where it ascends trees in the dappled shade of the understory. Give it bright indirect light and a chunky, free-draining mix, and provide a moss pole or support for its climbing habit. Water when the top inch or two of mix has dried, and let it approach dryness between waterings rather than sitting wet, since the roots rot in soggy conditions.

Toxic to cats & dogs & humans
Araceae contain insoluble calcium oxalate crystals, which irritate mouth and digestive tissues if chewed. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
