Philodendron alatiundulatum has extremely frilled petioles making it pretty unique amongst Philodendron species. It's a fast and vigorous grower for us.
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.
