“Olkkala” This rose was found as an extensive thicket by an abandoned rail track close to Olkkala Manor, Southern Finland. The results of DNA analyses indicate that this rose is closely related to ”the Valamo rose”, R. gallica ’Splendens’. “Olkkala” is even more vigorous, growing to over 2 metres on good sites where it rapidly runs riot. It flowers for about four weeks from late June onwards. The medium-sized flowers are single, medium pink, paler towards the middle. In autumn the round, red hips and golden leaf colour are added attractions.
