Fan leaves are the big leaves that start at the bottom and go up the plant in pairs. In other words, ALL the big leaves are fan leaves.
When the plant starts growing, all you get are fan leaves until it's a few weeks old and shoots start appearing at the nodes.
I know it looks like the fan leaves are covering the shoots and blocking out their light, but they are needed to absorb as much energy as possible from the light (that's why they are big and fan out) |
