morning glory - leaves and vines

Ever since I was a kid when my mom grew morning glory outside our living room window, they've always been one of my summertime favorites. I remember laying on the sofa gazing sleepily at the mass of green leaves and pale blue flowers. 

This year I started some morning glory from seed, and they are beginning to take off. Even before their flowers bloom - with the combination of their heart shaped leaves with their determined yet delicate vines - they offer so much visual interest to a garden.
