Philodendron maximum is capable of producing some of the largest foliage in hte genus. Take a look at some larger specimens here. This species grows hemiepiphytically in nature and is a fast grower in our experience.
Like most Philodendrons, this variety prefers moist but well-draining soil and some humidity. As it climbs, it should be staked or allowed to climb up moss poles. In higher humidity environments, numerous aerial roots will form which gives the plants a beautiful look.
