I grow them and for me they're short lived perennials. I too leave them out over the winter time in a well drained flower bed and have one with a couple of small flowers now. I like the shape and colour of their leaves even if they're not in flower.
In late winter/early spring they'll give good colour and flowers with a lovely scent. I usually grow a Bromptom mix. I've grown them in pots although they've not done as well as in the ground 'tho they are more sheltered.
