Black-eyed Susan is a member of the
Aster (Asteraceae) family. The plants can grow up to 3 1/2
feet tall but are typically 1 to 2 feet tall and have bristly-hairy leaves
and stems. The leaves are alternate, sometimes toothed, widest at
the middle and tapering to pointed tips. Parallel veins run along
the length of each leaf. Flower heads are single at the top of each
stem branch, with each head about 2 to 3 inches wide and composed of a
dark brown rounded to conical, buttonlike central disk surrounded by 8
to 20 yellow, petal-like ray flowers.
In central Indiana it usually blooms late Spring to mid-Summer. Folk medicine used the leaves of the plant to make a tea and yellow dye can also be made from the plant. |
