· Here's a list of fruit and vegetable plants that produce a big crop of fruit, grow upright and taller in habit, and produce large crops of fruit in zone 5b:
Vegetables (these are all annual/seasonal):
Bell Peppers, Cayenne Pepper, Banana Peppers, Jalepeno Peppers, Okra, Pole Beans (require staking or trellis system). Corn is tall-growing but not sure you could say it produces "tons"? At least not just a few plants in a small plot. You might want to think about Asparagus as well, it's a perennial plant that can live up to 10 years or so.
Fruit Plants (these are all hardy):
Northern Highbush Blueberry, Bush Cherry, Serviceberry ('Regent' and 'Fergie'), Black and Red Currants, Gooseberries, Hardy Kiwi (will need trellis)
Hope this helped.)
