Broadleaf Weed – Three-seeded Mercury

(Acalypha virginica)

Three-seeded Mercury – also known as Virginia Copperleaf, Wax Balls, Copperleaf, Virginia Mercury and Mercury-weed – is a summer annual broadleaf weed. Acalypha virginica does not appear to prefer any particular habitat and can be found in most disturbed areas, woodlands, thickets, prairies and meadows, abandoned fields, areas along railroads and roadsides, thin lawns and flower gardens. Three-seeded Mercury can be found throughout much of the eastern and midwestern United States.

Identifying Three-seeded Mercury -

Three-seeded Mercury can be identified by its vertically growing, branched stems that are hairy to sparsely hairy. The foliage is glossy and sparsely hairy and develops a distinct copper pigmentation. In many areas, the leaves soon become damaged by insect feeding. Three-seeded Mercury has a shallow taproot with a secondary fibrous root system.

Blooming from July-October, Three-seeded Mercury features a spike of small, staminate flowers that lack petals. Reproduction is by seeds and cross-pollination is by wind.

Three-seeded Mercury Control -

Three-seeded Mercury can be a somewhat aggressive summer annual weed. Cultural weed control methods – including proper lawn mowing and watering habits – will not completely remove “Virginia Copperleaf” and should only be used as a supplement to professionally applied herbicides.
