What is a good term for plants whose parts, either as tubers, roots, or fruit/seeds are harvested and consumed? I exclude plants such as hemp and flax whose fibres are used, or, for example, poppies for opium.
agricultural products and especially fresh fruits and vegetables as distinguished from grain and other staple crops
Also from Wikipedia's 'Produce' article:
Produce is a generalized term for many farm-produced crops, including fruits and vegetables (grains, oats, etc. are also sometimes considered produce). More specifically, the term produce often implies that the products are fresh and generally in the same state as where and when they were harvested.
Generally, people don't call 'wheat' produce but it could be.
Also, this is entirely anecdotal but in American English, it seems like when talking about the noun, people usually emphasize the "o", so it sounds closer to "pro-duce"; and when talking about the verb, they shorten it, so it sounds closer to "pruh-duce".
