DESCRIPTION:
Pigweeds are annual broadleaf plants that germinate from seeds from late winter through summer. Several species occur;
the most common is redroot pigweed. Seedlings of all common pigweeds are similar. Cotyledons
(seed leaves) are long and narrow and are often red underneath. Prostrate pigweed (bottom, right) forms dense mats. Leaves
have distinctive light colored edges. Flowers of tumble pigweed (top, left) are borne in the junction between the leaf stalk
and the stem, rather than in spikes and have smaller leaves than redroot pigweed.
