- The Aubrietia-class sloops were a class of twelve sloops built under the Emergency War Programme for the Royal Navy in World War I as part of the larger Flower class. They were also referred to as the "cabbage class", or "herbaceous borders". The Flowers were the first ships designed as minesweepers. Like all the Flowers, the Aubrietia class were originally designed as single-screw fleet sweeping vessels, with triple hulls at the bows and an above-water magazine located aft, to give extra protection against loss from mine damage when working. However, the utility of the design was found to be as a convoy escort, and as such other classes took over the minesweeping role. The Aubrietias were re-classified as convoy sloops. Unlike the preceding Flowers of the Acacia, Azalea and Arabis classes, with their unmistakable warship appearance, the Aubrietias were designed to look like small merchantmen, in the hope of deceiving U-boat commanders, a tactic known as the Q-ship. These vessels were built by commercial shipbuilders to Lloyd's Register standards, to make use of vacant capacity, and the individual builders were asked to use their existing designs for merchantmen, based on the standard Flower-type hull. Two members of the following Anchusa group, HMS Chrysanthemum and HMS Saxifrage (renamed HMS President in 1922), survived to be moored on the River Thames for use as Drill Ships by the RNVR until 1988, a total of seventy years in RN service. President was sold in 1988 and preserved, and is now one of the last three surviving warships of the Royal Navy built during the First World War, (along with the 1914 light cruiser HMS Caroline in Belfast, and the 1915 monitor HMS M33 in Portsmouth dockyard).

- La classe Aubrietia fu una classe di 12 unità per la lotta antisommergibile costruite sotto l' per la Royal Navy durante la prima guerra mondiale, parte della più ampia classe Flower. Erano conosciute anche come Cabbage class, "classe dei cavoli", o Herbaceous Borders, "siepi erbacee". La classe Flower fu la prima di unità progettate come dragamine. Come tutte le Flower, la classe Aubrietia fu originariamente progettata come dragamine a singola elica, con triplo scafo a prua e il magazzino munizioni a poppa per maggiore protezioni da eventuali incidenti con le mine. Il progetto fu però trovato valido per la scorta ai convogli e le Aubrietia furono quindi riclassificate come navi scorta. A differenza delle precedenti Flower delle sottoclassi Acacia, Azalea e Arabis, che avevano un'apparenza chiaramente da nave da guerra, le Aubrietia furono progettate per sembrare come piccoli mercantili, nella speranza di ingannare i comandanti degli U-boot, una tattica nota come nave civetta (Q-ship). Queste navi furono costruite da cantieri commerciali secondo gli standard del Lloyd's Register, per sfruttare gli scali liberi, e ai costruttori fu richiesto di applicare ai loro preesistenti progetti mercantili lo scafo standard della classe Flower.
