I have a plant that I bought and the name of the plant is unknown. The leaves look like arrows and they are very dark green in color. When a new growth comes in one of the old leaves die and fall off. Please help me find a name for my plant.

I can only recommend you to take the plant to your local nursery to see if they can tell you what type of plant you have. Its hard to make an accurate assumption with your discription. Sorry!
