Morning Glories are blooming!

This year the morning glories germinated and produced lots of vines.  There's a window behind the vines on the side of the garden cottage; it's nearly all obscured by the vines.

The vines have been growing well, but have not had any blooms.  Culprits for this are too much water or too much fertilizer; we had not too much of either one.  So we just waited patiently.  Finally, over the past few days there have been new blooms each morning.  Yesterday (this picture) there were fifty-one blue blooms.
