Hairy Nightshade | Hellebore | Hemlock | Holly | Horse Chestnut

Hairy nightshade (Solanum physalifolium). This plant has mottled green and white fruits which should be treated as poisonous. It is increasingly found in vegetable gardens, mainly in the Bay of Plenty, but is spreading elsewhere.

Hellebores (Helleborus species). These plants are often grown close to houses and all parts are very poisonous.

Hemlock (Conium maculatum). One of our most poisonous plants; all parts should be avoided, especially young plants and seeds. The unpleasant smell and purple markings on the stem easily distinguish this from parsley.

Holly or English holly (Ilex aquifolium). The scarlet berries should not be eaten because, like most parts of the tree, they are poisonous. This well-known tree is mainly grown in colder areas south of the Waikato.

Horse chestnuts (Aesculus species). The seeds, commonly called conkers, are mildly poisonous. These should not be confused with the edible, but unrelated, sweet chestnut. It is mainly grown in colder areas south of the Waikato.
