Rose (Rosaceae)

Prairie Rose

Rosa arkansana Porter

This low-growing, perennial shrub has leaves that die back annually and fruits that persist into the fall and winter. Plants form clones by spreading runners and rhizomes. Roses are pollinated by bees, and have strongly scented flowers that also attract birds and butterflies. Plants have medicinal uses, and petals can be used to make perfume. Fruits, flower petals, and young shoots are edible for humans.
