DESCRIPTION:
Common groundsel is an early season weed in most areas, but can grow all
year in coastal areas of California. Seed leaves of groundsel are elongate,
with a blunt, rounded tip. The first true leaves have shallow teeth; the
third and fourth leaves are more deeply lobed. Groundsel grows up to 60
cm (2 feet) tall.
Leaves are alternate on the stem and deeply indented. Upper leaves are
attached directly to the stem, but lower leaves have a short petiole. The
green bracts
surrounding the flower cluster have conspicuous black tips that distinguish
groundsel from other weeds in the thistle family.
