I had some wal-mart bulbs for lilies and such and all I got were snails. After about a year of nothing, I fished out the bulb and threw it away. Wal-mart sucks for anything fish related. Especially plants and advice. IMHO go somewhere else.
I bought 1 pack from Walmart a month ago, came with 6 bulbs but one was messed up. I threw that one in the tank anyway to see if it grew. 3 grew and one is really big right now that I don't even think its an aponogeton. It is in my 10 gallon tank its out of the water. The stem of the plant is bent and there is one part thats out of the water and it looks like a flower is about to sprout. The other two do not look like this and are rather short right now. About 5 inches tall.
If you want to be safe, I would buy the Top Fin brand of the Aponogeton.
I bought a pack of 4 and 2 grew already in 2 weeks. I bought these at my local Petsmart.
