Nice thread, read through all the posts, instead of responding to a bunch of different posts, Ill make my comments in just this one..
A weird fruit I was introduced to in Florida, was the Jamaican fruit called "Akee"
This fruit also grows here in the D.R. I have seen it in "El Botanico" and in someones yard.
The fruit when not ripe, is toxic, when its ripe, it pops open, and you can eat the white stuff inside. The unripe fruit looks like its plastic, feels light, and even has little creases as if it was made in a mold.
I have never tried it.
Ok someone posted on the Annons, they do grow well in this country, and in the past were plentiful here, but they have all but disappeared. I think its because it has little commercial value ( its more of a backyard fruit ) and will produce little to no fruit unless you have a pollinator plant.
Here are some Annon varieties
Atemoya : cross between Squamosa and Cherimoya
Red Custard Apple ( Annona reticulata )
Soursop / Guanabana / Graviola ( Annona muricata)
By the way, the common Guanabana is such a very powerful medicinal plant,
here is a database link for it:
Databse Entry: Graviola - Annona muricata, Graviola - Annona muricata Graviola - Annona muricata Graviola - Annona muricata Graviola
Sweetsop, Anon, Sugar Apple ( Annona squamosa )
This is the variety known locally as "Anon" I have come across them here, but they are rare now. I have one of the "Kampong Mauve" ( purple variety ) growing in a pot, that I started from an imported seed, its doing well.
Cherimoya, Custard Apple (Annona cherimola )
Soncoya (Annona purpurea )
These i have seen in Florida, but not in the D.R. yet, although they should grow here.
A fruit I have not seen mentioned in this thread is the Carambola, these fruits can be very tasty/sweet if you get it from a good tree, the quality varies immensely from one plant to the other if planted by seed.
There are so many fruits that I would like to grow, wish I owned 20 Acres
