My terrarium is 35 gallons, and is dicided so that half is "land" and half is a pool of water with a recirculating pump that sends water down a small "fall" made of coral and shells back into the pool.

Does anyone know if the common aquarium plants, Amazon Swords (Echinodorus) can be grown with their roots in the water and leaves out in the air, ie not submerged, as is commonly done in an aquarium?
