History of Lewisia

Apart from its beauty, Lewisia has a rich history.
The plant was discovered by Meriwether Lewis of the historical Lewis and Clark expedition.
The Lewis and Clark Expedition took place from 1804 to 1806, following one of the most significant events in American history – the Louisiana Purchase. The Louisiana Purchase was a land purchase between the U.S. and France in 1803, in which President Thomas Jefferson bought the Louisiana territory from France, under the rule of Napoleon.
Meriwether Lewis collected a bitterroot plant (Lewisia rediviva) to add to the collection he would present to President Jefferson. Among other species, the Bitterroot was presented to Frederick Pursh for identification. After the plant was revived, Frederick Pursh, a German-American botanist, gave the plant its scientific name – Lewisia rediviva. The name honored Meriwether Lewis and his role in bringing the plant to the attention.

In 2009, the genus Lewisia was transferred from the purslane family (Portulacaceae) to the Montiaceae family.
