Bamboo plant, should it live forever in water, or plant it?

[Confuzzeled]

We've had this bamboo plant for about 2 years, it's lived in water and has sprouted loads of leaves. The last few weeks it's started to look a bit pale and I suggested to my dh that we put some soil in the bottom of the vase (since it looks like a bog anyway). Dh says no, they're meant to live in water but I've seen bamboo growing on soil so what do we do?

We've got a few bamboos in the garden and they are all in soil (in pots as they can spread like wildfire).

It sounds like you might be talking about a different sort though as you said its in a vase, so presumably indoors?

aah, sorry, just realised you probably mean lucky bamboo plants

Yes, they were given to us as long sticks that sprouted, they've done very well and getting pretty large. I wonder if all bamboo is the same and I could climatise them to outside?
