Quercus mongolica subsp. crispula

Quercus mongolica subsp. crispula - Mizu-nara

Mongolian oak (Q. mongolica) grows over a large range throughout East Asia and several subspecies and forms have been described, some of them even awarded the status of separate species. The most successful of these in Finland has been the maritime Japanese subspecies called mizu-nara (Q. mongolica subsp. crispula) because it is hardier in the Finnish type of climate, which is unsettled and changeable. The northern provenances from Hokkaido and Sakhalin Island are also hardy to severe frosts.
