Something flowered

I have those bulbs from petco too . No idea what they are either but mine have also flowered a couple times. they are great plants and seem to do well in my low light no extra co2 tank. I would really like to know what they are.

Sort of looks like my Echinodorus martii - well at least thats what I was told it was. Mine had a bulb like that it was 4" out of the top of the tank - it was under the canopy behind the light fixture so I did'nt notice it until I went to do the weekly water change yesterday.
