I've been told there is great Salak. My friend brought me some seeds and two made the journey. Most were taken from her. From what I can tell it is different than my three varieties.
Contrary to some reports indicating the abundance of salak in the Philippines, that fruit is nowhere to be found here. It's unheard of although rattan fruits which bear some resemblance to it is quite ubiquitous.
Ah! So JonM what fruit seeds would you suggest?
As Mugenia has said, many fruits found here are found in many parts of the world. Adding to the relatively common fruits previously mentioned that I recommend are jackfuits, chicos, marangs, mangosteen, star apple(currently in season), bignay, duhat or java plum, starfruit, kamias, tamarind, guava, and macopa or Java apple and its close relatives, pili nuts, and sugar apples. Avocados are common but it's a lottery when it comes to quality. Aratiles is so common it's left to birds.
Lesser known species of fruits that are often only well known in some localities are acerola, Rollinia, mabolo or velvet apple(Diospyros blancoi), lipote(Syzygium curranii), chempedak(only in Palawan), gumihan or pedelai(Bicol Region), hagis(Syzygium sp. - can't find species name), camachile (Pithecellobium dulce), cashew, berba(Lemon drop mangosteen), binucao (Garcinia binucao? - don't know if sp. name is valid), pahutan(Mangifera altissima, Luzon), huani(Mangifera odorata, Mindanao), galo(Anacolosa fructescens), tabu(Willughbeia elmeri? - not universally recognized sp. name, Palawan), palau saguit-saguit(Willughbeia sarawakensis, Palawan), and Paratungon(Salak relative but sour and used in wine-making instead. Palawan), and the gymnosperm "bago"(Gnetum gnemon). I forgot some species but most of them are even rarer.
