Cazgar... Crypts would look well... and loads of them!
Jourdan... What kind of look are you wanting?
Minstrel... Biohazard is correct. They are Draecena (sp??) and are actually plants that sometimes are used in Palludariums so need to be exposed from the water. They should do well on your windowsill though.
You must forgive me I just bought pretty looking plants from the shop which one is the one I should remove? Thanks folks glad I posted now
