Perennial Vegetable Questions

ok, so more than one or two questions here but all about perennial vegetables really

i am currently working on a property in Cheyenne, WY, zone 4(zone 5 on map, but not accurate because of microclimate created by vast plains)

and within the decade i will be moving down south, hopefully near the St. George, UT area


my questions are:

what would be the most reliable and productive perennial vegetables in a zone 4 with 14in average precip, high's reaching mid 90s in summer and sometimes -30F in winter?
what would be a good plant to encourage fungal growth?
What perennial vegetable is your favorite to munch on?

down south, things grow much better and produce much more biomass lol so i would assume that there are more varieties for this area, but does anyone have a recommended list of perennial vegetables that grow good in a zone 6-7?

basically i am just looking to get a general idea of what kinds of perennials i can get planted in both areas:)

Hi Devon,

You can check www.perennialvegetables.org for lists of species for different climate zones.

For the arid, cold west, also try these western US natives:
SUCCULENTS: Agave parreyi, Yucca baccata
CACTI: Prickly pears, Cylindropuntia imbricata
TUBERS: bitterroot, manroot morning glory, prairie turnip, biscuit roots, yampah, allium canadense
SHOOTS and PODS: milkweeds: A. syriaca, A. speciosa
FRUITS: Physalis longifolia
SEEDS: Cucurbita foetidissima

I love sea kale broccolis more than almost any other cold-loving perennial vegetable. They grow very well in Denver where it is high and dry.

thank you for replying Eric, i'll have to get to looking at that site and thanks for the list, i'll look into getting some of them planted:)
