Description

''Shinnersoseris rostrata'' is an annual with long branches with long linear leaves, the branches end with five or more pink flowers. Plants are uncommon and populations are local being generally restricted to sand dunes of the Great Plains. It is a threatened species in Minnesota, where it exists naturally on one sand dune complex in the extreme western part of the state. In Minnesota it is found on unstable sand dunes where wind blowouts produce shifting sand, the colonies are threatened by the suppression of fire which allows grasses and woody plants to take over the habitat.
