Palmer Amaranth
Palmer Amaranth
Life Cycle: Summer Annual
Description: A member of the pigweed family, Palmer amaranth is a troublesome summer annual. The egg-shaped leaves are arranged alternately along the stem. The petiole is as long as (or longer) than the leaf itself. Some of the leaves have a V-shaped "watermark", which is white in color. Not all Palmer amaranths will have the watermark. Another variable identification characteristic is the presence of a single hair in the tip of the leaf notch. As the plants mature, the female plants will have a very long terminal seed head.
