About this species

Native to upland areas of Africa and Asia, voodoo lily has flowers that emit a foul smell resembling rotting meat. This odour attracts insect pollinators such as flies. Despite its putrid smell, voodoo lily is popularly cultivated as an ornamental. Its popularity is due in part to it being one of the easiest aroids to propagate and one of the hardest to kill.

Overview: A tuberous perennial with a large, umbrella-like leaf on a brownish-red speckled petiole (leaf stalk) that appears after flowering.

Flowers: The flowering parts consist of a spathe (hood-like structure) wrapped around a spadix (flower-bearing spike). The large, twisting spathe (up to 1 m long) is yellow to brown with reddish-purple spots. The purple spadix is slightly shorter or the same size as the spathe.

Fruits: Red to bright purple berries.

Conservation assessments carried out at Kew

Sauromatum venosum is being monitored as part of the IUCN Sampled Red List Index for Plants, which aims to produce conservation assessments for a representative sample of the world’s plant species. This information will then be used to monitor trends in extinction risk and help focus conservation efforts where they are needed most.

Voodoo lily is cultivated as an ornamental. The tubers can be grown indoors as a curiosity; they can flower without soil or water, although the tuber should be planted and fed immediately after flowering if it is to be kept alive.

The roasted tubers of Sauromatum venosum are eaten locally.

This species at Kew

Sauromatum venosum is grown behind-the-scenes in Kew’s Tropical Nursery.

Dried and alcohol-preserved specimens of Sauromatum venosum are held in Kew’s Herbarium, where they are available to researchers from around the world by appointment. The details of some of these can be seen online in Kew’s Herbarium Catalogue.
