I have several varies of morning glory climbing the walls of my house. These are called UFO. I first saw them several years ago on columns outside the Festival Theatre in Stratford. I can’t recall if they were labelled or if I google them but I tracked them down, found seeds & planted them the next year. This year I planted them to climb above the back door. I use twine for them to climb. They are late bloomers – first blossoms were in mid-August & will continue until the first frost. Some mornings there are 10 or more in bloom.
