Nightshade but not deadly

These are the ripening berries of Bittersweet or Woody Nightshade.  Although the ripe red berries are tempting for children, it is the green berries that are more poisonous.  No-one has died from eating these since a girl in 1948.

Nonetheless it is not a plant to eat.

The plant scrambles over other plants and the purple and yellow flowers are quite attractive but easily overlooked.
