Dean...

Here in Wisconsin, we have 2 common weed nightshades.

Black or common nightshade - Solanum nigrum.  An annual to 1 ft here, but
larger with longer growing seasons. White flowers and black berries

Deadly or bitter nightshade - Solanum dulcamera.  A perennial climbing vine
with blue flowers and red berries.  A variegated variety of this weed is
offered commercially.
