Castor oil plant (Ricinus communis). The attractively mottled seeds are the usual parts eaten, sometimes with serious effects. The New Zealand plants usually have purple leaves.

Celery-leaved buttercup (Ranunculus sceleratus). This is one of the most toxic species of buttercup. It grows in wet places such as in ditches, along streams and around ponds and lakes. The parts most likely to be put into the mouth are the glossy divided leaves which resemble those of celery. Contact with mouth and lips can produce blistering, but fortunately the bitter burning sensation usually prevents material being swallowed.

Cestrums (Cestrum species). There are several species of these popular ornamental garden shrubs, with flower colours ranging from scarlet and rose to white or orange. Fruit colours are white, black, or sometimes red. All parts are very poisonous.

Cherry laurel (Prunus laurocerasus). The small black fruits have kernels which are poisonous.

Chilean jasmine (Mandevilla suaveolens). A climbing plant with fragrant white flowers which is usually grown on house walls or trellises. Like many other members of the oleander family, Mandevilla has poisonous white latex in all parts. The long pods are bean-like, but the seeds inside are small and winged.

Comfrey (Symphytum officinale and its hybrid S. ¥uplandicum). Although the leaves are used as a general tonic, if used in quantity they can be harmful over a prolonged period.

Corsican hellebore (Helleborus lividus subsp. corsicus). A commonly cultivated evergreen herb, all parts of which are poisonous.

Cotoneasters (Cotoneaster species). The pretty red berries, which nearly all species have, seem to be mildly poisonous, but have never caused serious harm. Because they are so abundant in gardens and public places, children may often eat a few berries without parents being aware.
