Morning Glories Climbing a Tree

My favorite flower is not universally loved. Although they are easy to grow, morning glories also tend to reseed themselves, and not always in the spot where they were planted. They are not particular about their friends, hobnobbing with english ivy or thriving in the same neglected spaces as poison ivy. To me, they are the essence of Art Nouveau--all curving stems and winding tendrils. They live up to their name, losing stamina and closing up by midday when the sun is out. Late risers may still find them in  shadier spots, like this old tree, where, as the day lengthens, their original sky blue blossoms deepen and take on a purple cast.
