The greater celandine (Chelidonium majus) is a yellow-flowering poppy, 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. The whole plant is toxic, containing a range of alkaloids, such as Chelerythrine; it may also cause contact dermatitis, particularly the latex.
The greater celandine is the only species in the genus Chelidonium, and is not closely related to the lesser celandine (Ranunculus ficaria).
[edit] Description
Greater celandine plants may reach 80 cm high, with deeply divided, 30-cm long leaves. The flowers comprise four yellow petals, each about 1 cm long, and are produced 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.
