the problem is ,there is sutch a thing as hydroculture, were you can grow a lot of plants in water,with pebbles to hold them, the only one I have heard called the water plant is duckweed, hope someone on hear knows better, good luck.

The plant press dictionary refer to the water plantain of north america Alisma plantago-aquatica, and the RHS plant finder refer to 4 genera in response to the common name of water plant :Achimenes, Euryale,Ranunculus and Sarracenia.

The `water plant` I`m aware of is the Achimene and often referred to as the Hot Water Plant. This is an indoor/glasshouse plant.Look this up and see if it fits your plant description.

I hope this has given you a few leaders to follow.

'Water plant'....could be a reminder!!

It's not Achimenes by any chance is it, the so-called Hot Water Plant?
