There's a flower that grows in myriad places
It's in a disease, it's found upon faces
It's found in the one who accuses a thief
It's found in the one who switches belief
It's found in all those who call themselves straight
As well as a very short timespan to wait.
It may be a hip or a drink that you boil.
Search in the sundew and the stuff made from oil.
The answer is a single English word.
