You can use Google, set it to search images, and search for any of a number of name versions; Dendranthema arcticum 'Chimo Red', Chrysanthemum arcticum 'Red Chimo', Chrysanthemum arcticum 'Chimo Red', Arctanthemum arcticum 'Red Chimo', etc. Didn't find a plain 'Chimo'; seems to be 'Chimo Red' or 'Red Chimo'. Take your pick of names. John, what names among these have you heard about?
