Photographed May 3.Photographed May 3.Also known as Quaker Ladies, these tiny blue flowers form tidy clumps in shaded lawns and roadsides. Small as the delightful four-petaled flowers are, they rise from a plant that seems tiny out of all proportion to the flowers. They generally bloom in late April or early May, but can continue to late spring.
