I did some trimming on my Rotala wallichii quite some time ago, didn't discard the whole plant, but instead just place them in a bucket of water. I don't remember how long I left them there, and today I check, I saw the emersed form.
Check out the pics...
Rotala wallichii emersed form and flowering
They even bear flowers in the emersed form, tiny purple colour flowers...nice and cute :D
If you can see from the picture, the plant is just kept floating in the bucket.....and still it grows, amazing!
