Same experience as that of Raven. Five years and no increase. History. Here and elsewhere, there seem to be such mixed reviews, almost as though there are different strains of the same cultivar. At any rate, it didn't like it here, an area that often has little snow cover, the fluctuating spring temps that characterize the interior of the country, and often hard late spring freezes. Such a negative experience that I am wary of its kids.
