This plant profile should be removed, or the details in the info section should all be changed to "N/A" and the position should read "non-aquatic plant". It's not only chain stores that dupe customers into buying this blight on the hobby (and numerous other non or semi-aquatic plants). My nearest LFS owner tried to tell me it was fully aquatic and when I flatly stated that it's not he tried to say it's semi-aquatic and just needs removed from the tank periodically. Don't buy this plant!!
I bought this plant knowing it wasn't aquatic. But to fill the space till I found something else I wanted to put there. After time I eventually found nothing and just left it. Hoping that it would rot away and force me to make a decision on what to replace it with. Its been in that tanks for 3 years now. It hasn't gotten much bigger. Maybe another 3 inches. But it is doing really well. Plus my cories like sitting on it. I found out that my mother had been buying and replacing it when it started to go. So.. ya..
This picture is of Ophiopogon japonica but it is the dwarf form Compactus/Kyoto Dwarf and those were definitely not grown in the water as it is not even a wetland plant. Looks great in the garden though and in bonsai. I love mine and also love Ophiopogon Nigrescens but not in a pond or in an aquarium unless you only want a temporary living vase arrangement it does work well for that "so there is that".
