Epipremnum pinnatum ‘Skeleton Key’ is a truly interesting looking Epipremnum that is thankfully gaining popularity. These climbing Aroids start out with leaves that resemble a Pothos (Epipremnum aureum), but once allowed to climb and mature, the leaves will transform. The part of the leaf closest to the stem will stay wide and rounded, while the rest will be a narrow strip, resembling a —you guessed it, skeleton key.
As with other Aroids, give these a good soak, but allow the potting mix to dry out between watering. They may be tropical plants, but they do not appreciate constant wet feet, and this will lead to root rot. At the same time, they also do not handle a potting mix that stays dry.
