Henbane
Poisonous 
Autumn 
Summer
This poisonous member of the Solonacea family (nightshades, potatoes, tomatoes) is an unusual and striking non native. The dramatic creamy yellow and purple veined flowers are an unusual sight, most often found in old apothecary gardens but also in sand and gravel near the sea.
It is a biennial with a shrubby habit growing up to 1m tall. The whole plant is very hairy and very sticky and produces a nauseous odour!

Leaves

Flowers
The flowers are very distinctive being bell shaped, 2-5cm across with 5 petals. They are a creamy yellow colour with purple veining and a purple centre. They sit at the base of the leaves one on each side of the stem.
Fruit
The fruit resemble a small green tomato, 10-20mm in diameter, sitting at the base of a large calyx (cup like structure).
Seeds

Stem

Habitat

Possible Confusion

Smell
Nauseous – thus the stinking nightshade name.

Rare in the UK and northern Europe.
Other Facts
Henbane was and is used and grown for reputed herbal medicinal purposes. However it has long been associated with witches and hallucinations despite its lethal toxicity. Recoveries of seeds from a Viking grave have backed up suggestions that this could be the plant used to induce the rage of the berserkers in battle.
