useful privacy hedge

I'm in coastal oregon.. outside of the salt spray zone. I want to grow a privacy hedge under some large western cedars. I would like something that does not loose it's foliage in the winter. The spot gets good sun in the summer, but I think the house may block come sun in the winter.
I'm thinking of building a stone raised bed to plant the hedges in.
I don't know what kind to pick. I would like something with dual purpose.. something that either makes people or chicken food.
Any ideas??

Do a search for fedges and you will get a lot of suggestions for edible hedge plants.

I don't know if they're all feasible in your location, but I've got pineapple guava, pomegranate, rosemary and am planting a yaupon holly (only north american plant with good caffeine content, supposed to be a delicious tea). In my area these are all shrub sized (or small tree) evergreens that tolerate hedge style pruning. Actually, they also have all have prominent flowers that attract a variety of pollinators during different times and the yaupon has winter berries that the local birds love.

pineapple guava sounds really neat I've never heard about it. I just looked it up. Sounds like it's good down to 10 degrees. It should do ok here. Do you know how fast it grows? Couldn't find anything about that.

What I can find suggests they're typically quite slow growers. Many sites recommend them as container plants, which certainly supports that thought.

Mine were very small when I planted them and have tripled in size in the past year. But we've had an unusually nice year for growing new plants, they have a very sunny location, and young plants often have an early surge of growth that doesn't maintain itself.

I would say huckleberry maybe.

I definitely plan on planting huckleberry here but I don't think it will get tall enough to make a good privacy hedge. Am I wrong? When I've seen it in the wild it was always 3 or 4 feet

i d love to grow (somewhat cold-hardy) tea-plant. camelia sinensis something. there is a "sochi" variant that should be very hardy.

they are evergreen, have nice flowers and produce tea.

sadly, my seeds did not germinate

I was looking into this for a colder climate (zone 5a) and tentatively identified the following candidates:

Mahonia / Oregon Grape

Barberry (some are invasive)

Japanese Plum Yew

I second the evergreen huckleberry - Vaccinium ovatum!

Another good evergreen shrub is Arbutus unedo, strawberry bush or tree.
