Plant a coral honeysuckle (Lonicera sempervirens). They are beautiful, hummingbirds love them and they do not run rampantly wild like some other honeysuckles do. I have had mine growing on the entry arbor to my garden for about 12 years, I guess, or maybe a bit longer and it has stayed where I want it to stay.

Here's one example of coral honeysuckle:

Coral Honeysuckle 'Pink Lemonade'

There are many varieties of Lonicera sempervirens. The one in the link is the one I have. I believe another one commonly found in stores here is "Gold Flame" and there's one with a more reddish-orange flower called "Major Wheeler".

Coral Honeysuckle "Major Wheeler"

At our house in southern OK, coral honeysuckle stays green almost year round, though its foliar color will change to a burgundy-tinted green after extremely cold weather. I don't know if that is true further north. I'm in zone 7b.

If you want something that stays evergreen in winter, you might want to plant some sort of shrub instead.

Are you bringing this to the SF, Dawn? :D

Yes, I am!

Neither Pink Lemonade nor Goldflame are cultivars of Lonicera sempervirens. They are cultivars of a hybrid species, L. x heckrotti and will not remain evergreen. They do however offer great fragrance, which the native L. sempervirens does not. And they are not considered an invasive honeysuckle, although both are big, rampantly growing vines.

Quince makes a nice brushy bush. The birds love to perch in mine. A vitex tree left to grow like a bush would be beautiful in the summer. It wouldn't cover in the winter though. Whatever you do, I would make it with multiple types of plants. It will give you interest. I would plant for birds, bees and butterflies :)
