Oh that is such good news!!!! My aquarium plant care is really limited unfortunately. Its a 10 gallon with regular gravel, no CO2, and standard 19W florescents that came with my All Glass hood. I do add a bit of Seachem Flourish fert every few days though. Do they need lots of iron? I'm thinking of buying the iron supplement soon. Do I need anything more to care for them? I had already asked my parents about getting rid of them and they said no to pretty much every solution I suggested and I didn't want to sneak them into the LFS tank!!
I've got three of these bulbs, and I think you are right about IDing them Man Yu. All are sprouted, but only one has unfolded leaves. The first leaf was just three toothpick-like points, but the new 2nd and 3rd leaves are so much broader. Now I'm wondering, how did these three sneak into my apogeton bulb package???

I've never even heard of those before, are they more rare?
Is the latin name nymphaea and the common name dwarf lotus?
