Midwest Park Arboretum in the northeast part of Stromsburg has more than 75 different varieties of trees and plants, with more added each year. Stromsburg has been designated as a Tree City USA for 20 years. As the site for the annual Arbor Day celebration., it has an historical gazebo, playground facilities, and picnic tables.
As a special millennium project, a plaque was added to the bronze sculpture identifing it as "Swedish Pioneers." The sculpture was cast for the city in 1976 by Stromsburg native Dana Westring.
