Have lived lots of places and climates and you can forage in most, with some good books and possibly some good friends, but this current one is the most difficult for me. It is arid high alpine with not overly productive soil for gardens. Because of the very short season to grow things its a challenge that way too.
Went out around the neighborhood this summer to see what was growing within 2 miles should it be needed here. But, was surprised how little people grew that was edible, at least in the front yard I’m sure they had edibles in the backyards but there are few alleys here to check that out. Russian Olives (very limited time of year to pick them and uses safely), a few gooseberry plants, and some crabbe apples (for pectin), lots of lilacs so that was good (for fevers), we did plant some fruit trees but don’t have an expectation of much fruit in most years.
