Hey
I've seen alot of people using plastic plants around my area - they don't look too bad, some look quite good

But anyway, if you're not looking to get real aqaurium plants I would highly reccomend plastics as : They do not die, they don't need any care an attention what so ever (appart from maybe cleaning off algae once in a while - but if you have a loach that won't be a problem at all) and as far as I've seen they're quite cheap.
I tend not to like them as the tank doesn't look as realistic and they don't grow, but that is far from the point
Appart from plastics I have no idea what else you could get,
don't use terranian plants (eg bonsai trees, rose plants (hey, just thinking off the top of my head here

)) as they are not evolved as per say to the aqaurium and so will die very, very quickly, rot in your tank, poison the water and thus kill your fish
