Summer annual broadleaf
A summer annual that may grow to 40 inches in height with distinctly toothed leaves. Hophornbeam copperleaf is primarily a weed of agronomic crops but can also occur along fencerows, in landscapes and in nursery crops. Seedlings have two round cotyledons that are slightly hairy. Mature plants have leaves that are alternate, egg- or diamond-shaped, with finely toothed margins. Flowers are inconspicuous and occur on long axillary or terminal spikes. Hophornbeam copperleaf seedlings are often mistaken for prickly sida, but prickly sida has one round and
one heart-shaped cotyledon.
