Rugosa rosa (Rosa rugosa) is a cultivated fugitive that was first introduced to Finland at the end of the nineteenth century. The oldest observation of its spread to nature is from 1929. It grew in Seili back in 1986, but was eradicated according to official instructions. Admittedly though, there is nothing to stop birds from carrying hips laden with viable seeds back to the island.
