Hemlock Conium maculatum

Best Time to See
Habitat Coastal

The white flowers appear in dome shaped rounded clumps, which are usually 2-5 cm across.

This plant can be quite tall, growing up to 2 metres and can smell quite unpleasant. The stems are mostly large, hairless and have purple spots along their length. The leaves are fine and look similar to ferns.

All parts of this plant are poisonous and all members of this family should be treated with caution, notably because hemlock can be easily mistaken for cow parsley.


Widespread in most of England and the lowland areas of Wales, also found in some southern or coastal areas of Scotland.


Likes damp places and can be found on scrubland, waste land and by streams.
