The paper presents four plants used as an agricultural season indicator by Mao Naga tribe of Manipur, India. Agriculture is the main occupation of the tribe and they have a unique way of knowing plantation season for different crops by observing the flowering of some plants. The indicator plants are peach (Prunus persica), wild cherry (P. carmesina), camel foot (Bauhinia purpurea) and dancing girl (Mantisia spathulata). The information on plants used as season indicators may help understanding the global warming and climate change in recent years. There is a need for involving interdisciplinary research to unveil the mystery of folklore science for the prosperity of mankind.
