pitcher plants are nicer. tho you can't keep in the office because they need plenty of sun and water. but they have really cool pitchers, and i mean really cool!!

you can put fertiliser to replace bugs, but you might end up overdosing or killing the plant (since there's no big watering to flush the excess fertiliser residues away), or you could end up with a plant that has no flytraps or pitchers at all because why would they need those if they already can get their nutrients from fertiliser?
