I love morning glories! and I'm particularly in favor of those purple or blue ones. They just add a wonderful refreshment in the morning, really. These are a light blue variety I found at roadside, Beijing, when I was traveling to there last month. The color is just so touching!
One thing about morning glories is that they are so modest in nature, and they thrive everywhere there's decent light and moisture. The trumpets of beauty sing the glory of the sun.
This dark purple one is in my patio. I took this picture a day after coming back from Beijing -- it's still in the season of morning glories!
