About
Arum maculatum, commonly known as cuckoopint, jack-in-the-pulpit and other names (see common names), is a woodland flowering plant species in the family Araceae. It is native across most of Europe, as well as Eastern Turkey and the Caucasus.
Safety
All parts of the plant can produce allergic reactions in many people and the plant should be handled with care.
The attractive berries are extremely poisonous to many animals, including humans, but harmless to birds, which eat them and propagate the seeds. They contain oxalates of saponins, which have needle-shaped crystals that irritate the skin, mouth, tongue, and throat, and result in swelling of throat, difficulty breathing, burning pain, and upset stomach. However, their acrid taste, coupled with the almost immediate tingling sensation in the mouth when consumed, means that large amounts are rarely taken and serious harm is unusual. It is one of the most common causes of accidental plant poisoning based on attendance at hospital emergency departments.
Where it grows
It grows in woodland areas and riversides. It can occasionally grow as a weed in partly shaded spots.
