Things to consider when discussing permaculture. Asparagus along old barns or in rows. Plant and do not harvest the first year crop. You will be good after that.

Kiwis and yes they have arctic varieties and can grow just about anywhere. More vitamin C than an orange.

Strawberries always plant different varieties. Blueberries do same as above. Peaches are more work because of all the diseases and pest. Fruit trees may require a IPM (integrated pest management program).

Blackberries and raspberries. Plan ahead and do your homework.
