Yes they will grow.
I have 3 growing now, from the larger pack of those. One, the first one to sprout, has always sent flowers up and its leave always look dead. The second one, has never sent flowers and had dark green leaves, very pretty.
The third one, is tiny, with dark green leaves and just sent a flower up. I have picks of them somewhere.
I believe they needed more light than my 38 led was providing, as I let them float at the top? and they did much better, then the first one I kept at the bottom of the tank.
Those flowers? well I had one that did give some seeds, and it produced the first 2 leaves. It was in my throw away plant/scungie stuff when i found it, lol and a snail.
I forgot about it and the water dried up and it died.
Mine started growing about 4 or 5 days after dropping them in the water. I started then just in a bare tank with some jewels in it, and not heated. Just in the bathroom window for light.
The flower in this pic is only about 3 days old, it actually grew to over 3.5 inches long, and the second one in the pic did the same thing. One day when i cleaned the tank, I pulled the flowers off, hoping the plant would do better.
The bulb, acually grew really fat, in like 2 days time just before it sent those flower up.. I thought it would explode! It was so, alive. It freaked me out, reminded me of a story about someone getting a cactus that had spiders in it.
