The Flower class comprised five sub-classes of sloops built under the Emergency War Programme for the Royal Navy during World War I, all of which were named after various flowers. They were popularly known as the "herbaceous borders" or the "cabbage class"
The "Flowers" were designed to be built at merchant shipyards, to ease the pressure on yards specializing in warships, and as a result had a distinctive "merchant marine" appearance. Originally used as mine-sweepers, the "Flowers" were later employed as convoy escorts. One group, the Anchusa’s, were employed specifically as decoy vessels (Q-ships).
Some 112 "Flowers" in total were built for the Royal Navy, and a further eight for the French Marine Militaire. Of these, 17 RN and one French "Flowers" were sunk.
The five sub-classes were:
- Acacia-class sloop: first group to be built, in 1915. 24 vessels built in two batches of 12. Two sunk during the war.
- Azalea-class sloop: 12 vessels built in 1915. Slightly modified Acacia's; two sunk during the war.
- Arabis-class sloop: 36 vessels built 1915, a further eight for French Navy. Five British, and one French vessel sunk.
- Aubretia-class sloop: 12 vessels built 1916; two sunk.
- Anchusa-class sloop: 28 vessels built 1917. Saw service as Q ships; six sunk.
