Description:
Flowering heads have from 8 to 30 (average 12) blue to lavender, or white, ray flowers that surround a central cluster of dark lavender disc flowers. Involucral bracts are long and lance-shaped, with green tips. Leaves attach individually. The lower leaves are broadly heart- or arrowhead-shaped, and have winged petioles. Upper leaves are narrowly lance-shaped and attach without petioles. Lower leaves measure up to about 15 x 6 cm, and have conspicuous teeth. Upper leaves measure up to 4 x 1.5 cm, and have either smooth margins or some inconspicuous teeth. Stems and leaves are covered with very small hairs. This species occurs in woodland settings from September through October. Native to N. A.
