Alupag is a very tasty fruit from South East Asia.  It is endemic to the Philippines but has now reached other counties too.  It is a close relative of litchi and bears tasty fruits.  It is cultivated too.  However, alupag cultivation has not been able to pick up much because it is always compared with litchi or longan which is preferred by consumers over this fruit. Native to southeast Asia, with concentrations in the Philippines and Indonesia.

Fruits of alupag showing pulp and seeds

            New plants can be raised from seed, air layering or grafting on longan seedlings.  The seeds do not retain their viability for long and therefore should be sown as soon as possible.

Fruiting starts from the age of five in plants raised from seed.  The air layered plants may come into bearing during third or fourth year.
