Coreopsis is an early example of the kind of sloop the Royal Navy developed after the First World War. Q-ship service was one possible use, but it was an adaptation rather than the class's original purpose. The Flower-class vessels were first ordered for minesweeping. A specialist minesweeping requirement produced ships that could later take on Q-ship and other duties.
