Can this wreath hang on an exterior door?

Yes. It is rated for indoor and outdoor use, and the UV protection is meant to slow fading in sunlight. A covered porch or door will keep it looking better longer than full direct sun.

Does it come with lights or decorations?

No. It is a plain boxwood wreath, so lights, ribbon and bows are added separately.

Is 22 inches big enough for a standard front door?

A 22-inch wreath covers a good share of a standard 36-inch door and leaves the edges visible. It also works on larger wall spaces, above a mantel or over a window.

How does it compare with a real boxwood wreath?

It keeps its shape and color all year and needs no water, but it has no natural scent and the leaves feel artificial. Real boxwood looks and smells better but dries out and drops leaves.
