I have to tell you though, I have always had a fascination with the leaf scars on houseplants, especially philodendrons. I love the look of them.
What is a leaf scar, you may ask? A leaf scar is the mark left by a leaf after it falls off the stem of the plant. It is where the petiole was attached.
|You can see on this plant above, the places where the petioles attach.|

In the picture above of the close up, (sorry it is a little blurry) you can see the vascular bundles. Another definition is in order-vascular bundles are, as defined in the dictionary:
|Heart shaped leaf scar|
I saw this philodendron at the New York Botanical Garden. Most of the scars look round, but the one was shaped like a heart.

Most of these pictures were taken at botanical gardens. Most of us couldn't support something this big in our homes. Mine is getting quite large but I doubt it will ever be as large as these. The scars are starting to prominently show though, and I love it!
