Horizon Roses 2011 contains 2,138 reports on 313 roses by 85 reporters. The reports include 67 new roses not mentioned in prior issues. All comments are candid and reported in the words of the reporter (with some abbreviation and condensation). The reports are set forth alphabetically and include statistics of the show results of the reported varieties. In addition, information is provided on known sources for the reviewed varieties.

Horizon Roses is produced entirely by volunteers under the direction of Bob Martin, National Editor and nine regional editors. The regional editors solicit and compile the comments from selected top exhibitors in their region and forward them for final compilation.
