Woods' Rose
Rosa woodsii
Rosaceae · broadleaf · native
Woods' rose is a thicket-forming native shrub ranging from Minnesota west to Alaska and south to Arizona and Mexico, found in streamside thickets, disturbed ground, and open woodlands. The plant reaches 2-10 feet and bears compound leaves with typically 5-7 (occasionally to 11) ovate leaflets.
Woods' rose is remarkably adaptable to both wet and dry soils and is equally at home in full sun or part shade. It spreads vigorously via rhizomes and can become aggressive in moist fertile sites; regular mowing or pruning keeps it in bounds. The plant requires minimal care once established and is reliably hardy across much of the region.
