Quick Notes:

Height: Up To About 1 1/2 to 3 1/2 feet tall.

Flowers: Yellow flower heads are 1 to 1 3/4 inches across, with 20 to 50 bright yellow ray flowers ("petals"). These do not drop off, but are persistent and become faded, papery, and turned downward in age. The flower heads are mostly borne singly at the tips of the stems and branches on long naked stalks, 4 to 8 inches long. Each head produces at least 100 achenes, which are rodshaped, about 1/8 inch long, light brown, with many longitudinal nerves on the surface.

Flowering Time: Mid March - November.

Leaves: Soft, woolly leaves are alternate, clustered largely at the base of the plant and divided into irregular close set lobes, or some are divided again. The upper leaves are few lobed, or may be narrow and smooth edged.
