narrowleaf sunflower

Narrowleaf Sunflower is a member of the family Asteraceae, which includes herbs, sometimes shrubs or vines, rarely trees, with simple or compound, alternate or opposite leaves. Flowers small, but organized into larger heads resembling a single, radially symmetrical flower cupped by a ring of green bracts. Flower-like heads: tiny, radially symmetrical central flowers form the disc; larger flowers around the edge; the rays, strap-shaped and resembling petals (however, all flowers in one head may be disc flowers or rays.)
