One of the reasons the Cebu blue pothos is often mistaken as a monstera is because it develops fenestrations when it matures. As a young plant, the Cebu blue has thin and pointy leaves without holes. But mature plants have leaves with zig-zag splits, often spanning from the midribs of the leaves to the edges. The thing with Cebu blue pothos is that it takes too long to reach maturity, sometimes taking up to two decades before the fenestrations show up on its leaves. That's good news because you get to enjoy the silvery-blue glint of its leaves for a very longs time.
