|Weed Description: A low-growing
summer or winter annual, or biennial, that forms a rosette of grayish green woolly
foliage. Found throughout the United States but most common in the South.

grayish green, without petioles, rounded to oval, 1.5-2.5 mm long, 0.75-1 mm wide.
Young leaves taper from the tip to a broad petiole.

Fruit: An achene with an attached bristly pappus to aide in weed dispersal.
|Leaves: Arise from the rosette
or connected to the elongating stem (cauline). Rosette leaves 4 inches long, approximately
3/4 inch wide. Stem leaves alternate, grayish-white and woolly, without petioles
(sessile), and progressively reduced in size moving up the stem. Leaf margins may be
wavy or without teeth (entire).
