Agree, it's from the British Isles or UK thereabouts. I however don't agree that it's a fast plant. A fast plant would be something like cabomba that grows an inch a day.

Agreed hatonnia is a native plant, to me in the uk anyway. however I would suggest that it is a cold water plant. British rivers even in summer never get above 22C so cooler temperatures will suit this pretty plant much better.
I have this in my tank and I don't see it being a background or even mid . Mine stays low too the ground . I must say it is a finnicky plant ! I missed a feet dose and it seemed to be the first plant to let me know Blake
