The big one in the middle is a tiger lotus. They grow very fast and produce a new leaf that reaches the top of my tank within a week. There are ones that are short and stay close to the substrate which is what this one was supposed to be and then there are ones that will grow to the top of the water surface like this one. Actually not my favorite because it provides too much shade for the dwarf sag carpet I was attempting which grows taller in low light. They come as bulbs that you bury half way in the substrate. You can buy these at Petsmart/petco for next to nothing in a pack of 4. I think petsmart calls them lily bulbs. I will be transferring mine into the new scape, it provides good shade for my crypts.
