Ask the Expert: Can you identify this plant?

Hi – this plant has tiny white flowers with 5 petals and small green berry clusters (I don’t know if the berries will change color eventually).  Can you identify it?

Thanks

It is a little difficult to tell from the picture, but I think it is Carolina Horsenettle (Solanum carolinense).  It is not actually a true nettle.  The berries should turn a yellowish color. Carolina Horsenettle has spines on the stems and is considered a noxious weed in most states.  It also has toxic properties. Be careful when your handle it.  Take a look at the Carolina Horsenettle on the MissouriPlants.com site for a positive identification.
