Name that Plant!

This plant is probably easily identifiable. In fact it's a good bet that if you live in the south you have it in your yard, your neighbors yard, your school, your bank and pretty much everywhere you could think to put it! I saw rows of this at the home improvement store today which prompted me to make this post. Take a guess at it or if you know what it is then tell me what you think of it. I'll withhold my opinion on it until later!
