Arrow-leaved Aster
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.
