You can still get the smaller, wilder variety in other places in the world. For instance, the Philippines.

I remember walking into a small village store in Costa Rica to be confronted by about 10 named varieties of bananas, and noticing in the core a box just marked "apple". It was a cool inversion of the usual pattern in the US (and Europe).

Every SE Asian country will have a few types of bananas available locally. Even Australia is jumping on the band wagon and I can get a couple more varieties now. I can even get plantains regularly.

But we’re talking about mangoes and bananas and pineapples and calling those “tropical fruit” when there’s so many fruits in the tropics.

Apple bananas in Hawaii are delicious and available at the local Costco.

As you say, the “gros michel” cultivar is mostly dead commercially, although there are attempts to get a variant resistant to fungal disease.

I’d like to taste a Gros Michel some day.

Miami Fruit grows then and will ship: https://miamifruit.org/products/gros-michel-banana-box-order. I’ve never tried it though
