There is no exact blooming season of Rafflesia, but it is believed that rainy season is more favourable. Thus, if you want to visit Sabah region, where there is the highest concentration of these plants, monsoon period in April-May or September-October would be perfect.
How long do Rafflesia flowers live?
Furthermore, flower lifespan is only 5-7 days thereby placing a temporal bottleneck on the process of pollination (Beaman et al., 1988; Nais, 2000).
When can one see the Rafflesia bloom?
Although flowers generally bloom throughout the year, November, December and January can be regarded as the peak flowering season as the frequency of blooms is high. Seeing a blooming rafflesia is certainly the highlight of a trip to Gunung Gading, but the Park and the whole Lundu area are well worth visiting anyway.
