About
Roselle (Sabdariffa gossypiifolia) is a species of flowering plant in the family Malvaceae, likely native to parts of Africa. In the 16th and early 17th centuries it was spread to Asia and the West Indies, where it has since become naturalized in many places. The stems are used for the production of bast fibre and the calyces are commonly steeped to make an infusion popular in many places around the world.
How to grow it
In the initial years, limited research work was conducted by University Malaya and Malaysian Agricultural Research and Development Institute (MARDI). Research work at Universiti Kebangsaan Malaysia (UKM) was initiated in 1999.
