A review of edible orchids in Malawi

Abstract

Orchids are mostly known for their beautiful flowers, and food-flavoring products which make them a resource of 
great economic importance in the global horticultural and food industries. But in the Southern African region, orchids 
are particularly important for their tubers which are used for food, and are therefore traded within and across the 
countries. A number of researchers have reported a dramatic rise in the demand for these orchids in Zambia, which 
has forced traders to seek the tubers from outside the country. This has raised concerns about their sustainability as 
high exploitation pressure threatens the future existence of these wild edible orchids. Based on information from 
literature and from reconnaissance, ethnobotanical and social economic surveys that were undertaken in Mzimba 
and Kasungu districts, this paper reviews and examines these developments, with a focus on Malawi. The review 
highlights some of the areas that require more attention in terms of research and policy interventions, namely 
identification of all edible orchids, domestication of edible orchids, and trade controls.
