Charles McKellip (Brand).  7.8.  Red.  This is a large, loosely-built, semi-rose, deep red peony.  We think it is the most perfect in form of all the deep red varieties.  It is especially beautiful in the bud.  This is one of the varieties whose good qualities are impressing themselves more and more upon the public.  When the next Symposium is taken, we feel quite sure that it will rate above 8.5.  It comes into bloom just after Mary Brand, and we believe it is as good a red.
Charles McKellip was voted on in the first general Symposium and then received its low rating of 7.8.  It was a comparatively new flower at that time and had not been talked about very much, but did receive more than 20 votes.  All varieties that received 20 votes or more in that symposium were not voted upon in the next symposium which accounts for its present low rating.  Five years from the taking of the last symposium the next general symposium will be taken and then we prophesy that Charles McKellip will come into its own.  At Duluth, Minnesota, where as fine peonies as can be grown in the entire world are produced, and where the reds come simply gorgeous, Charles McKellip is the finest red of all.
