 All parts of this plant are highly toxic

Laburnum anagyroides is an exotic, deciduous shrub growing to 4-7 m high. In New Zealand, it has become naturalised and grows wild in the South Island and the southern half of NorthIsland in the cooler, upland areas.
During late spring bright yellow, sweet-scented, pea-like flowers, arranged in pendulous racemes 10-25cm long hang from the branches.
The leaves (3-8 cm long) are generally trifoliate and oval, with long petioles, smooth on the upper side and hairy on the underside.
The fruit is a green flattened pod, 4-7.5cm long. The pods contain 2-7 kidney-shaped, dark brown seeds.

All parts of this plant are highly toxic if ingested. The toxic principle is an alkaloid called cytosine which is extremely poisonous to humans as well as goats and horses. The symptoms are nervousness, stomach and intestinal irritation with nausea, vomiting, and diarrhoea; irregular pulse, convulsions and coma.
