Weeding

Here in the High Desert and in many other places, Corn and Field Gromwell are common weeds found along roadsides and in fields. Both weeds are annual with several stems branching from the base. Their tiny white flowers develop in the leaf axils, bunching together while at the bud stage and in bloom. The most significant difference between both are the hairy leaves of Corn Gromwell on both surfaces. These field weeds are invasive, self-seeding and grow anywhere, in any type of soil.
