Silver thiosulfate (STS, chemical formula Ag2S2O3) is an inorganic chemical that can promote early flower growth and promote flower duration in a variety of plants.[2][3]

An aqueous solution of silver thiosulfate can be prepared by mixing solutions of sodium thiosulfate and silver nitrate. When used for plant assays, it is prepared using excess thiosulfate, giving the [Ag(S2O3)2]3– complex ion.[4]
