Bluets, Quaker Ladies, Azure Bluet
Bluets are natives of central and eastern North America. The name “Quaker ladies” may be a reference to their white bonnets.
Identification: Azure bluets, as you can see from the photos at right, aren’t necessarily azure. Most often pale blue, they range from white to a darker shade of blue. Bluets are diminutive, less than 8" (20 cm) in height. They produce dense clusters of flowers, each about ⅜" (1 cm) across, with four petals and a yellow center. I see them most often nestled in small brilliant patches in lawns.
