i have 2 tiger lotus and both of them have put out several leaves that have stayed towards the bottom. the plants are only about 3" tall. but now one of them is sending a leaf straight up. it looks like an arrow towards the top of the tank and has a stem about 3" long. the leaf hasn't uncurled yet either. i know that it will eventually send leaves all the way to the top of the tank and flower even, but i thought it would make several lower leaves first?
