..a bit of a tall order I think, something 2 x 2, hardy and year round interest, but I shall give you two that I grow and see if you might be interested in these.
Choysia 'Goldfingers'. This small shrub is evergreen, quite a bright plant, with yellow leaves and scented white flowers in summer. It has proved exceptionally hardy for me, out in all weathers in a container, suffered continued freezing, snow drifts, the lot, for the past 3 hard winters. I live in cold east Anglia.. The tips get a little burnt and dry but it soon recovers. As an added bonus it's pretty drought tolerant too but welcomes a good drink with some food as they all do...
Fargesia mureliae 'Simba' - this dwarf bamboo type grass - non invasive - will live happily in a container for many years. Mine has been in one for at leat 4 years now without repotting and like the one above has suffered all the extremes including freezing wind. It is evergreen but like a lot of grasses/bamboos can look a bit 'deciduous' and a a little 'tatty' at the worst times but will soon recover [providing the owner does not fret], and green up again.
I love both these plants and wouldn't be without them for containers. See what you think.
