A circle of lavendar would look great Treza.
Lupins easily get battered esp when in full flower. You would need to stake them well. They are martyrs to aphids and then to snails....they look awful after flowering with mostly tatty leaves so bear this in mind. Currently one of my lupins is over 3' tall and will be staked before any strong winds arrive.
colour is good but don't throw masses of different colours at it.
Dwarf evergreen grasses would look good too.....festucas with their evergreen blue leaves and movement.
dwarf hebes, euonymous emerald and gold, pittosporum Tom Thumb are all sun loving wind resistant and colourful evergreens. A phormium like Sundowner or Cream Delight would add a focal point of colour too.
I would also look at hardy salvias...in blues and whites, veronicas in blues, whites and reds. Mounds of silver foliage from artemisia powys colour, or convolvulous cneorum or santolinas would love the sun and wind.
If you want to ring the changes consider marguerites and cosmos....pinched back to make them sturdy cosmos will flower their socks off until late autumn
