Hey silly400...Welcome to the forums
Yes they do sprout if your water conditions are right for them. I have had people give them to me from time to time and have found that when they do sprout they rarely survives. I have always found it best to buy Aponogetons from a grower and then propagate them in the tank.
Planting is done with only half of the bulb in the gravel if you can tell which is the root end

. You might try sprouting them in a window between wet paper towels.
My feeling is these things are most often placed for impulse buying.
You are right Cichlids and small plants do not get along.
