About

Kalmia angustifolia is a flowering shrub in the family Ericaceae, commonly known by various names including sheep laurel, wicky, and dwarf laurel. Like many plant species of infertile habitats it has evergreen leaves and mycorrhizal associations with fungi.

How this plant poisons

Kalmia contains a glycoside, known as andromedotoxin. It is poisonous to mammals. Hence, it can be unwelcome in pastures. Several of its folk-names testify to the plant's toxicity: 'lamb-kill', 'sheep kill', 'calf-kill', 'pig laurel', 'sheep-laurel' and 'sheep-poison'. It is also known as narrow-leaved laurel and dwarf laurel.
