Is this an aquatic plant?

[aquarius]

i bought two plants called palm plant or something. it literally looks like a small version of a palm tree. after i brought it home, i started suspecting that it wasn't an aquatic plant. since i had two, i put one in the water and the other one i planted in a pot of soil just to see what will happen. but has anyone heard of this type of plant?

there are a few plants kept in aquariums that are not "true" aquatic plants. but for your info, many plants for the aquarium trade are grown hydropoincally out of water, as it is much easier to cultivate in mass production. when they are submersed they change there structure by getting rid of the cellulose that maintains there rigidity, because they dont need it in water.
or something like that anyways hehe

Do you mean umbrella palm? It is a beautiful plant sold in water gardening centers for ponds. I have some growing in a pot OUT of the water as well as some growing IN the water. I think it does well either way, as long as it's not completely submerged. It can grow as a bog plant, around the perimeters of a pond also. There are two kinds, the dwarf and the giant. The giant has bigger fronds and grows about a foot or two taller than the dwarf.

Sound very much like umbrella palm. A marginal.

As a rule, (there are exceptions of course), if a plant can "stand up" out of water, it is possibly not aquatic. Aquatic plants use the water to support themselves. The common exceptions are certain Crypts and Swords that grow in areas which flood for part of the year and are boggy the rest. These have underwater leaves which are soft and floppy. When the water recedes, new leaves grow which are more robust.

Unfortunately, many people buy an unusal looking Sword, put it in their tank and are dismayed to see the leaves rot away, then they chuck it out, when in fact, they were the emrgent leaves and the new growth would have started soon. Some plant nuseries grow Swords and Crypts in bog conditions because they are easier to manage.

It may also be a Dracaena species, they are often sold as aquatics since they can acclimate to water culture (roots and lower stem only) and some of them resemble palms.

I doubt it's a sago palm, but I have seen them in an aquarium. They are not aquatic plants. My parents have some in their yard.
