Conoclinium coelestinum (L.) DC.
Mist-flower, blue mistflower, blue boneset
Order Asterales Flowering plants with a central disk flower and surrounding petals, like daisies
Family Asteraceae The aster family, which also includes daisies and sunflowers; from the Greek ἀστήρ, "star," for the star-shaped flowers
Genus Conoclinium From Greek κῶνος (konos), "cone;" and κλινίον (klinion), "little bed"
Species coelestinum "Sky blue," for the flower color
Blue mistflower is native to North America.
Identification: Plants are 18-36" (45-91 cm) in height. Leaves are roughly triangular (deltate), opposite, wrinkly, with blunt teeth (dentate or dentate-crenate), up to 3" (7.6 cm) × 2" (5 cm). Flowers appear in clusters that are almost flat-topped, and 1-3" (2.5-7.6 cm) around. The flowers are brushlike disc flowers—composed of 40-50 threadlike disc florets—that are blue or purple.[1] Flowers are ¼-⅜" (6.3-9.5 mm) in size, appearing from July to October. Technically these are composite flowers, like other members of the enormous aster family, but this species lacks ray flowers.
