Great thread topic! I had no clue you could eat magnolia petals.
I think my 'Hot & Spicy' oregano might be the more nearly evergreen of my greek oregano varieties, although it eventually dies back most years also. The other greek oregano plants might have a little flex to the leaves/stems yet in late winter, but even if they are not totally dead looking they seem to put out new growth just from the base of the plant each spring.
What about some of the more unusual "small fruits" like honeyberry, gooseberry, etc? I don't know what is evergreen and what isn't, with them. Hm... seems I've heard pawpaw is evergreen? The only time I got my um paws on some little trees, they went toes-up by end of summer, so I don't know about them either.
