About this species

Arum pictum is unique in the genus Arum in its autumn-flowering, and in this respect, as well as in its horse dung-like scent, resembles members of the related genus Biarum. The shiny, purplish and silver leaves are very beautiful, and persist through the winter.

Geography and distribution

Native to Majorca (Mallorca), Minorca, Corsica, Sardinia and the west coast of central Italy.


Overview: A winter-growing herb with a whitish tuber 5–7 cm across.

Leaves: The arrow-head-shaped leaves are about 30 cm long and 15 cm wide. At first they are shiny and purplish, later becoming silvery or whitish.

Flowers: The flowering stem (spadix) appears with or before the leaves, and smells strongly of horse dung. The spadix is 8–13 cm long, the appendage stout, cylindrical and purplish-black. The sheathing bract (spathe) is 9–19 cm long, 4–6.5 cm wide, greenish on the outside, deep, velvety purple-brown on the inside, with a mottled, greenish tip, and is slightly hooded. Three whorls of organs are found at the base of the spadix and enclosed in the folded spathe: the uppermost is a whorl of bristly staminodes (sterile stamens); in the middle there is a large cluster of small, male flowers; beneath there is a cluster of larger, female flowers.

Fruits: The fruits, which are red when ripe, are berries 5–11 mm long.

Threats and conservation

The habitat of Arum pictum, like that of all Mediterranean coastal plants, is under pressure as a result of spreading urban development, particularly building for tourism.


Arum pictum is cultivated as an ornamental.

Arum pictum is easily grown in a large pot. It should be kept dry in the summer, and watered in the winter (until May).
