I bought a pack, which was for i think $3. And out of the 12 or so bulbs that were in there, mabey 7-8 grew. there were a ton of the aponogetons. 2 tiger lillys and a onion plant which didnt look like it would grow and didnt. The 2 tiger lillys are growing in now and one leaf reached the surface! the aponogeton grew fast and i repanted some in my puffer tank. They all grew those stalks with little split flowers at the ends. As for the onion. if it doesnt have green stem coming out of it when u buy it. don't get it. Heres some pics of the aponogeton.
