Flowers are clustered in 2s or 3s at the end of branching stems in the upper part of the plant. Individual flowers are about ¼ inch across, white to pale blue or occasionally pink, tubular with 4 sharply pointed lobes and 4 stamens with creamy white to yellow tips that turn blackish with age. The inside of the tube is hairy. The bracts at the base of the tube are narrowly triangular and about 1/8 inch long. Flower buds are often pink.
Leaves and stem:
Leaves are narrow, to 1¼ inches long and ¼ inch wide, toothless and hairless, stalkless with a pointed tip. Attachment is opposite and there is a small whitish triangular appendage (stipule) on opposite sides the leaf node. The main stem is smooth and 4 sided, with rounded corners.
Long-leaf Bluets more often go by Latin name Houstonia longifolia, but the accepted name in Minnesota is Hedyotis longifolia.
