While on holiday we saw many examples of beautiful epiphytic orchids, co-habiting with trees, seemingly just hanging out in the air, which I believe is where they primarily get their nutrients. Another name for this type of lifestyle is 'air plant'.
A surprising fact I found out while reading about these very pretty dendrobium orchids is that they are dynamic air cleansers - particularly of chemical solvents like toluene and xylene - 'vigorous' was the word used to describe their ability.
