Anything canned, no.
Anything roasted or cooked at some point, no
A lot of seed in packets is good for more than a year or two.
You need mature but uncooked whole seed.
Popcorn I think will grow as it wouldn't be heat treated or it won't pop, right?
Birdseed can be millet, that's a corn like plant with a spray of seeds at top. Whole corn from birdseed, sunflowers of course. Safflower will grow but wasn't very pretty to me.
Papaya- I had a bunch of them volunteer last year from compost. They are fast growing and tropical looking, sort of like a green Castor bean plant.
