I lived in the San Juan Islands, WA State. We have a wild Rose that grows like a weed out there. Five petals, shades of pink and rather prickly almost like a Rugosa. In Alaska they call a similar rose Sitka, and here we call ours Nootka. Are they the same Rose or not. They sure look the same. Barbara
The three local natives are RR. gymnocarpa, nutkana and pisocarpa. R. gymocarpa has flowers the size of a dime. R. nutkana has much larger, mostly solitary flowers. R. pisocarpa has intermediately sized flowers in clusters. Non-native species naturalized in this region include RR. canina and rubiginosa.
