2.107 *Rosa setigera (Rosaceae Family), Prairie Rose or Climbing Rose
As one common name (climbing rose) indicates, Rosa setigera, prairie rose, can attain some stature (height, 2-5 m or more). Two varieties, v. setigera and v. tomentosa, share somewhat overlapping regions. The species ranges in the north from New Hampshire west to Ontario, Wisconsin, Iowa, and Nebraska. From the northern limit it is found in all states south and east. The uninitiated may mistake R. setigera for the aggressive alien multiflora rose, as both are bushy with climbing canes and armed with recurved prickles (occasional with R. setigera). However the much larger pink to whitish-pink flowers (4-8 cm broad, blooming in mid-July) distinguish R. setigera from multiflora rose, which has pyramidal clusters of abundant small white flowers (2-4 cm broad). As illustrated on page 114, the pinnately compound leaves of R. setigera are distinctive with only three leaflets (sometimes five), whereas the multiflora rose has seven or nine leaflets. This plant is found in wet-mesic to dry-mesic soils in full sun or partial shade. Its Coefficient of Conservatism is rated at 5. When the rose hips ripen to a red color, they can he collected. The hips (8-12 mm long) contain several yellowish seeds that are hairy on one side (3.8-4.2 mm long). For germination the seeds should be cool-moist stratified for 2 months [11], but germination may occur in a second growing season. Fall planting is a good option. This rose may not be evident for several years after planting.
