hi, i'm new to this site, and am looking for perennial vegetables that i can grow down to zone 3. i live in alaska. i have a garden, but would love to add perennial foods whenever i find ones that will grow here without them being killed by our long cold winter. i would also be interested in hearing about any perennial vegetables/grains that could be grown as chicken feed up here. i know they grow barley in the interior here. thanks for your site.
