The Lily Nook has a lot of lilies and ship them all over the world. They also have a great website that has many pictures of the lilies that they carry and a lot of articles. This is the address of the page with all the articles. It should answer your question on planting and growing lilies.
Lilies are very easy to grow. I have several kind, naturalizing lilies, day lilies and Asiatic lilies. They like partial sun, well drained soil. They come up year after year and multiply. I don't do anything after I plant them except put stakes beside the large Asiatic lilies to keep them standing. Only bad thing, bunnies like to eat them so I fence mine.
