| Besides alfalfa and asparagus, there's apples, peaches, and a few dozen other fruit tree produced from perennials, along with nuts, from all kinds of varieties, including pines. Then there's grasses which produce seed each year and don't die over the winter, though some we wish would die over the winter. We tend to not eat the seed of ornamental and prairie grasses, but birds do well on them and plant a fraction of what the eat, nicely coated in fertilizer.
And then there's berries, like the weed mulberry, as well as rasberry, blackberry, and mony others, not to forget rhubarb and elderberry. Elderberry and dandelion are reputed to make tasty wines, like grapes that also are perennials. Not necessarily grown in all parts of the world in fields as big as for corn, beans, and wheat, but significant farm industries where the climate and soil make all these grow well and survive the off seasons. Even the seed of oak trees have been eaten by animals, though I've not seen humans thriving on them.
