The Lewis and Clark Native Plant Garden is a beautiful garden created by the Rivers Across Lewis & Clark Sweet Grass County Bicentennial group. Montana native plants were collected by Lewis & Clark during their historic expedition between 1805 and 1806. Even though the plants were familiar to native Americans, these plants were new to science at that time and were considered significant discoveries. The garden has interpretive signs relating to the wonderful assortment of plants and interesting facts of the expedition through Sweet Grass County in July of 1806. Some of the native plants were named for Lewis & Clark, such as Montana's fabulous state flower, Bitterroot, Lewisia 'rediviva', Blue flax, Linum 'lewisii', Clarkia, Clarkia 'pulchella' and more! Walking through the gardens will be a memorable time full of beauty and history.
