Answer
What plants give year-round interest?
A layered scheme of evergreens, winter form, bulbs, summer flower and autumn colour.
In short
A good scheme layers evergreen structure, plants with strong winter form or bark, spring bulbs, summer flower and autumn colour, so something is always doing the work. Year-round interest is a design outcome, planning the planting so the garden never has a dead season.
