A lot depends on preferred colours, preferred season of interest and also how cold and exposed it is in winter as well as how much rain it gets and what type of soil you have - alkaline, neutral, acidic, sandy, silty, loam or clay - and how much maintenance you are able to do. Some plants look after themselves, others need regular pruning, shaping, dead-heading.
Do you see it from your windows or just when out in the garden? That makes a difference as to whether it needs to look good all year or just in the more clement months.
Either way, I would plant a mixture of spring bulbs with perennials or maybe a good year round shrub to give foliage, flwoer and maybe perfume a different times throughout the year.s.
