I found the selection at Petsmart and Petco to be pretty rough. It varies store to store, but lots of stuff mislabeled, and selling lots of nonaquatic plants as aquatic. The plant tanks were ill kept, as well. I am a big believer in starting with plants in great shape, that are suited to your specific conditions.
If you can, order online. There are lots of places like Planted Aquariums Central that have great plants. Watch out on shipping costs, obviously, and try to bulk order if shipping is spendy. Also, every forum (including this one! yay!) has a classified section with folks selling their plants. I have found them to be usually reasonably priced and in great shape, and you usually get more than you pay for.
