Will the best place to start, would be at a good online plant store that has a very large selection with photos, and profiles on the plants. This way you can pick out what you like and than see if you are meeting the requirerments for the plants you. Most chain store and LFS are not just catching on to the market of planted tanks so there selection are very small, however it good to take a peek every once and a while because they sometimes you can gfind a jewel. Make sure you know your GH and KH of your water as some of the more exoctic plants have requirerments just like fish. Shipping is a factor you need to look at not just cost but what the weather is like during shipping and delivery. Also, you should except plants that have been in a box for 3 days or longer they will just melt away as soon as you put them in your tank.
Tiger Lotus look nice.
