There must be a list somewhere of what can survive frosts...? Resource URLs!

...& even freezing thru tender stages of food plant development, maybe even specific to zone 5?  So i googled thinking a hit multiple jackpots from URL description but only one of top 3 pulled thru & i bet only partially. The plants I'm looking for are regular veges, greens, flowers, medicinal herbs that can make it thru frosts & even somewhat deeper freezings during early tender stages of development, but by flowering stage no threats of frost, usually. Tho we have experienced up here (CDN Rockies) a few Junuaries & even at least one Julyuary. Talk about scrambling words, but they do refer to climatic reality.  Thanks. Let's all grow what we can to re establish dwindling food security. Thanks, mainly for a list.  But posterity will thank us all for averting climate chaos. Here's the winner of my search string: https://www.gardeningknowhow.com/ornamental/flowers/fgen/annual-plants-for-cold-climates.htm

Try looking at Plants For A Future.
They have a big database of lots of plants, searchable by almost anything you can think of.

Dave Halsey, who has a great permaculture site in Prior Lake Minnesota (probably Zone 5) mentioned the Natural Capital Plant Database, which is here: https://permacultureplantdata.com/
He has a video on youtube "Ecological Designer Daniel Halsey hosts Geoff Lawton..." where he talks about how he puts a design together, and mentions that in one of the steps.
