Mimosa was a clipper ship that gained fame for carrying the first Welsh emigrants to Argentina, South America in 1865.

Mimosa had already seen many years of service by the time it transported Welsh emigrants to Argentine Patagonia, South America.

[3] Before the voyage, the emigrants assembled at various points, not always their places of origin, to prepare for the journey, including Aberdare, Birkenhead, and Mountain Ash.

Mimosa sailed from Liverpool, England on 28 May 1865 to Argentina, South America with a group of about 153 passengers with Captain George Pepperell and a crew of 18.

In 1875, the Argentine government granted the Welsh settlers ownership of the land which encouraged hundreds of others from Wales to join the colony.
