Joseph, I know the MGs in your photos are growing "up," but have you tried them in hanging baskets? I've had terrible tangles in the past when starting MGs from seed under the lights (they get away from me), so I was thinking that once they got started I could bring them upstairs and separate them... but I have more window space available as hanging space...
I have visions of morning glory vines twining all around the edges of my back deck canopy this summer!
