Chelidonium majus

Primary tabs

The greater celandine (Chelidonium majus, aka. 'Tetterwort') is a yellow flowering plant in the poppy family, native to Europe and the Mediterranean basin. It is also widespread in North America, having been brought there by settlers as a herbal remedy for skin problems such as warts as early as 1672.

Greater celandine may reach 30 to 120 cm high, with an erect stem. The leaves are deeply divided, 30-cm long. The flowers comprise four yellow petals, each about 1 cm long, with two sepals. The flowers appear from May to July. The seeds are small and black, and possess an elaiosome, which attracts ants to disperse the seeds (myrmecochory). A double-flowered variety, a naturally occurring mutation, also exists. It is considered an aggressive invasive plant in natural areas (both woods and fields). Control is mainly via pulling or spraying the plant before seed dispersal.

The greater celandine is the only species in the genus Chelidonium, and is not closely related to the lesser celandine, which is in a different family.
