Too often, when I search for new varieties of edible plants, I find resources that cater exclusively to vegetable gardening; which are, for the most part, annuals. When limiting the search to perennials, I find that most well known plants are deciduous, or tropical/sub-tropical. I decided to start a thread to share the few edible evergreens I've found with everyone, and to hopefully see the list grow.
All plants listed below are at least marginally hardy to zone 7. (*) Denotes that the plant is marginally hardy or requires shelter/winter protection.

*Corsican Mint (Mentha Requienii)
Sorrel (Rumex Acetosa)
