Bittersweet

 

Bittersweet or Woody Nightshade is an inconspicuous plant scrambling over other plants for support.  It has small but exotic-looking flowers, followed by bright red berries, which are at their most poisonous when unripe and green.

There is a record of one death of a nine-year-old child in 1948 but there is little danger of serious poisoning.  Most children seem to be immune, although occasionally eating the berries can lead to tummy upsets and drowsiness.

As usual it is better to show them the plant and educate them rather than trying to eradicate it.
