Hi Joakim
It is Cyclamen africanum; a seedling from Sandy Leven's multi Forrest medal winning plant that originated from Jim Archibald. ( see the forrest medal section on the home page of the SRGC web site.)
I am not 100% sure that it is true africanum, it could have some hederifolium in it.
It has very large well marked leaves and grows happily in an unheated glasshouse, the flowers are quite large but are dwarfed by the size of the leaves.
I have another plant at the base of a south facing wall which has been out for about three years now.
I have been told that if it was africanum it would not survive the cold we get even under glass but I have not told the plants that.
