The "Great Interregnum" is what I call the period between the dying off of summer flowers and the advent of fall foliage in mid-October. There is no color to photograph. In most years, people fill the void by putting out pots of chrysanthemums, but I see precious few this year.
So, I rummaged through my virtual files, and found these beauties, which I photographed in May of 2018. They come up every year in raised beds on Waltham Common near City Hall. They caught my eye, as a bright, midday sun suddenly set them ablaze. For more, see my earlier post, Tulip.
