Two species of native wild rose are common in the sand prairie region south of Chicago. In oak woodlands, savannas and xeric prairies, the pasture rose (Rosa carolina) is a common perennial low growing woody shrub. The taller (up to 8') densely shrubby marsh rose (Rosa palustris) grows in wet areas and is especially common along marsh borders. Generally the marsh rose blooms in July and just a bit later than its lower growing, dry land cousin.
Rosa palustris is popular with gardeners, because it's able to grow in very wet and acid locations where most other varieties of rose cannot. The cultivar (Rosa palustris, var. scandens) has double flowers.
If you are working on restoring an area in the Chicago region, please be sure you know the difference between the native and quite desirable Rosa palustris, and the non-native and seriously trouble-making Rosa multiflora before you begin to destroy plants.
