The arrow-shaped leaf that appears in winter under hedges, and which in August leaves a spike of bright red berries stuck in the ground with no leaves around it. The berries are the main risk to children.

How to tell it
A thick glossy arrowhead leaf, often with strongly marked pale veins. The flower is a greenish spike inside a sheath, and in summer only the spike of red berries remains.
What it is confused with
Common sorrel
Rumex acetosa
Both have arrow-shaped leaves. Sorrel's is thin, matt and lemony; arum's is thick, glossy and burns at once. Anyone gathering sorrel for salad must know this by heart.
Open sheet →What it is for
None. The whole plant carries calcium oxalate crystals that burn the mouth and throat instantly, which in practice prevents large ingestions, but one bite is enough for an emergency room visit.
