Apparently the plant grew in Númenor and was brought to Middle-earth by Númenóreans during the Second Age. Among the Dúnedain it was known as sweet galenas, and in Gondor it grew as a wild herb, appreciated primarily for its fragrant blossoms. Among the Gondorians it was known popularly as westmansweed, a reference to its origin.
It was not until the Third Age, in the Shire where it was first domesticated, by Tobold Hornblower of Longbottom in Southfarthing around S.R. 1070. Despite its foreign origins, the Hobbits (possibly those in Bree) were the first to use it for smoking. From Bree the habit of smoking pipe-weed spread to other regions, as well as to other races, such as Men, Dwarves and Wizards.
The Wizard Gandalf learned to smoke pipe-weed from the Hobbits and was often seen blowing smoke-rings. Saruman initially derided him for this, but at some point he took up smoking himself. After the destruction of Isengard, pipe-weed was found among its stores, but the Hobbits Merry and Pippin failed to realize the sinister implications of the discovery that Saruman had had commerce with the Shire.
The common Gondorian name of pipe-weed was Westmansweed.[source?] The more noble name was galenas (a Gondor Sindarin form of of the proper Sindarin form galanes), meaning "pipeweed" (or "sweet smelling growth"[source?]).
