My friend Bob and I went Ft. Collins Colorado on Tuesday (09/29/2009) to view the annual flower trials. Spectacular! This is a cooperative effort between CSU and wholesale growers to display flowering plants to their best advantage. See http://www.flowertrials.colostate.edu/. Growing conditions are closely controlled and documented. Judging was sometime in August so some of the plants were not at their best but most still looked great (instructive to see which ones had best tolerated the low temperatures).
