^ here's the thread where we've "been there, done that" - there is no clear consensus on how aquatic this plant is (so far) and, for that matter, we're not even certain that the ID is correct...

Since you have some, I'd put some in your tank submerged and put some at the waterline... I'd love to hear some followup & see some pics of this after you've had it for a while.
