Compared to extensively bred garden varieties, wild roses are not much to look at. Their tiny flowers do not get much wider than two inches, and may not get much wider than those of blackberry, with only about five petals. Flower color ranges only between pale luminescent white and pale pink. Bloom is typically rather brief in mid spring. Only a few healthy specimens bloom again later.
The main advantage to wild roses is that they are ‘wild’. Once established, they do not need much more water than they get from annual rainfall. Without pruning, canes of larger varieties develop into intimidating thickets that bloom annually. Smaller types stay short, but are intimidatingly thorny nonetheless. The deciduous foliage is not bothered too much by mildew, blackspot or insects.
Some types of wild roses appreciate a bit of pampering that might be offensive to other wild plants and most natives. Winter pruning, occasional summer watering, and perhaps a bit of fertilizer improve bloom. Alternatively, pruning after spring bloom may stimulate a second phase of bloom. Long canes can grow roots where they touch the ground, and grow into new spreading plants.
