There Is Plenty of Plant-To-Plant Variation in Waterhemp (07/07/16)

I received several inquiries last week about waterhemp. The conversation goes..."I am nearly certain its waterhemp, but it doesn’t look quite right”.

There Is Plenty of Plant-To-Plant Variation in Waterhemp

I received several inquiries last week about waterhemp. The conversation goes...”   I am nearly certain its waterhemp, but it doesn’t look quite right”. There is tremendous diversity in waterhemp, especially waterhemp that is 12 to 24 inches in size. Plant architecture, stem color, leaf size and leaf shape are all unique characteristics of waterhemp.

Waterhemp tends to be dark green in color due to surfaces leaf waxes. Stem and leaf surfaces are smooth and there are no hairs on the plant. Finally, flowering structures are open and located near the top of the plant and at the tips of branches.
