 June. Eastern Siberia. In 1898 F. H. Horsford said of this : 

 " the first to bloom with me, and one of the most attractive in 

 the list. It is one of the most dwarfed ; flowers large, blue, 

 yellow and white : it comes so much before the others that its 

 capsules, as a rule, all fertilize before any of the other species 

 come into flower."
