We will mention Lilium harrisonianum instead and list it separately. Maybe it´s a 4n-chromosome-set which comes true from seeds either. Its habitus and flowers are supposed to be a wee bit taller and larger.
We received bulbs and seeds from Berthold Gross some years ago, additionally to seeds from the RHS.
