I bought 3 seed packets in the spring of mixed varieties of morning glories and planted them around the entire perimeter of the fence in my backyard. The vines grew quickly but I only had the purple ones bloom during most of the summer. Once the weather cooled off it was an EXPLOSION of blue! Whats even better is that they completely cover the jungle of weeds and vines that grow in uncontrollably from my neighbors yard. If you click on the top photos you can see how much of the fence they cover.
