They are rather rare and do not exist naturally. One plant is a strain of pansies which have been genetically bred (from a genetic mutation) to produce entirely black petaled flowers. These are the FL350 Black Pansies, where FL350 is the strain number. There are other flowers with spots or edges of the petals which are black, and others which have a very deep purple color that may be mistaken as black, but as far as I know, the FL350 strain is the only commercially available pure black flower that currently exists.
