It is believed that rambutan is not originally native to Sri Lanka, being brought over by the Portuguese from Malaysia. In any case, mixed with the Sri Lankan soil the seeds of rambutan have acquired the distinctive yet astonishing taste.
Rambutan season starts in May when the first fruits appear on trees and stretches into August. Malwana is the center of Rambutan cultivation with huge orchards of Rambutan trees. Many locals grow Rambutan in their gardens. If you happen to be in Malwana, try Malwana Special - a local kind of Rambutan with bright red outer shell.
