Crypt. Wendtii Bronze I assume. I have the green variation of that. They root deep and hard lol.
All Crypts seem to be deep-rooters. I also have a C. Aponogetifolia only for a month and when I tried to move its location it was too late - the bugger won't budge at all.That's no joke!! I had one that was sort of getting lost in my swords. I can't believe the effort it took to pull it out of the substrate.
Wendtii's have a lot of phenotypical variety. Mine never grow more than a couple inches tall, but some people have their's growing 10-12"
