Split-leaf philadendron growing

Watching a split-leaf philadendron grow from seed is quite amazing.  It is believed that the split-leaf will only develop “split leaves” when it feels to have the right sun and nutrients to prosper and grow.  As the initial leaves develop, they are whole, without any split leaves.  The plant grows larger, and the leaves grow bigger.   The question is “Will the leaves split, and if so, when will the leaves split?”  When a new leaf comes out, if comes from the stock of another leaf.  The split-leaf philadendron leaf grows big from within and then opens to the world.  The other leaves are taking in the sun and the nutrients and the “inner leaf” which can’t be seen by us is growing strong inside.  And when that leaf is ready to open, it comes out.  It has used the energy the other leaves provided to grow on the inside.  The leaf came out and it was a split leaf, and it was happy.  It was its first split leaf.  Yeah plant!
