Magnolia × wieseneri

This cross between the Japanese bigleaf (also called whitebark) magnolia (M. obovata) and the Siebold magnolia (M. sieboldii) just bursts with tropical luxuriance, and is very promising in Finnish conditions. Older nursery stock may be rather tender but Gothenburg Botanic Garden has produced the varieties ’Aashild Kalleberg’ and ’Swede Made’ from apparently hardy parents, which may well prove hardy in southern Finland, too.
