Holly (Ilex aquifolium)
|Blackberry||Blackthorn / Sloe|
The holly is familiar to everyone, and the plant produces small, poisonous bright red berries. Ingesting these can result in vomiting, diarrhoea and drowsiness and a little as two berries can induce these symptoms in a child.
It's often believed that if the holly trees are full of berries, then a harsh winter is on the way.
