I planted morning glories in two large planters on each side of my studio doors. They climbed up the strings and down, over the doors, and up and down the opposite side. There was much foliage, but no blossoms! It was so hot and dry this summer, they baked in the afternoon sun. I watered them like crazy. Then this fall, after most of the foliage was gone, the morning glories started to bloom, and there was no stopping them! They bloomed until I pulled them out two weeks ago to string Christmas lights around the studio doors.
Some of the blooms drooped down in front of the door. Here is Charlie wearing a live morning glory blossom behind his ear.
