About
Drosera burmanni, the tropical sundew, is a small, compact species in the carnivorous plant genus Drosera. Its natural geographical range includes the tropical and subtropical regions of Asia (India, Taiwan, Southeast Asia, and China's Guangxi, Guangdong, Yunnan, and Fujian provinces) and Australia. It is one of the fastest trapping sundews as well, and its leaves can curl around an insect in only a few seconds, compared to the minutes or hours it takes other sundews to surround their prey.
In nature, D. burmanni is an annual, but in cultivation, when grown indoors during the cold months, it can live for many years. Since D. burmanni is an annual, it produces large amounts of seed. Drosera burmanni has been considered a powerful rubefacient in Ayurveda.
