Botanical name:  Arthropodium cirratum
Maori name:  Rengarenga
Common name:  Rock Lily

Rengarenga is found around coastal regions of the North Island and the upper South Island. It is recognised by its thick fleshy green leaves. 

The plants can form extensive colonies and in summer they have white flowers with attractive golden yellow centres. The flowers are borne on 30cm long stalks.

Rengarenga was used as an occasional food source by Maori. The thick fleshy roots were eaten after having a long steaming in an earth oven.


Arthropodium is a Southern Hemisphere genus.  New Zealand has 3 species, all endemic.
