I have a dwarf red lily that grows from a bulb. It was already grown into a good sized plant when I bought it, but I think you can buy them just as bulbs, too and grow them yourself. They can live in low light but won't grow very quick. Ever since I increased the light in my tank, I can't control how many lily pads it shoots up. It seems like I get a new one on the surface every two days- and It's a 55 gallon tank, so I think it's 2 feet deep. Anyway, it's a cool plant. It will grow a lot of leaves that stay short, and if you get enough light it will shoot up tons of lily pads to the surface. It's also pink and green colored, so it's very cool looking. Not sure where you can buy just the bulbs, though.
