@LastManStanding in the US it really depends on where you are.
In places with large international-origin populations, those markets carry a very wide range of the home country fruits and vegetables.
Speaking for Indian produce, the only things I haven’t been able to able to find fresh (that I’ve looked for) are chikoo (zapota / sapodilla) and tadgola (toddy palm fruit / ice apple / palmyra). Chikoo actually originates in central America, but I’ve yet to come across a version here in the US.
I used to complain mosambi / sweet lime wasn’t available either, but it actually does grow in CA (and Mexico) - it just rarely makes its way to the east coast where I am (there was once a sighting at my local supermarket, but never since).
Vegetables are mostly available at Indian markets, and sometimes other Asian and hispanic markets when there’s overlap in consumption.
When I visit India these days, previously “exotic” vegetables like broccoli and mushrooms are now commonplace (at least in large cities) - the local vegetable vendors even stock them, no need for a specialty store visit. (Actually I was surprised to learn that broccoli - not native by any means - was so plentiful in the winter that it was cheaper than many native vegetables. )
What falls into this category for you?
