Even within the traditional herbs there can be quite a variety. For example, try Blackurrant sage - the leaves smell wonderfully of blackcurrants and the flowers are a zingy red/pink. Here in my Buckinghamshire garden it makes a bush of about 3 feet, and survives several winters - if it doesn't then just replant it. Also try lemon verbena (NOT lemon balm, which is a terrible coarse weed) which has the most gorgeous lemon scent. Grow it in a pot, and don't be dismayed if it appears dead in spring, it takes a long time to leaf up. You could try majorcan Pink or Tuscan blue ( much deeper than the species) rosemaries - mine do well in pots. And how about "blue" chives ( allium nutans) not really blue, but more so than the usual ones, and bigger.
Hope this helps.
Good luck
