If you look closely at the leaves of these two lovely plants, you'll notice that they're quite different. Alocasia nebula's leaves are a little dark and might require a bit more care than some other plants. They like a nice, humid environment with a moderate temperature. Meanwhile, Alocasia elaine's leaves have a lovely smooth texture and its growth takes a little longer than Alocasia nebula. You could even say that this plant is somewhat tolerant of lower humidity levels! I hope this helps you to know a little more about these two lovely plants! If you think of anything else, please feel free to reply to my answer.
