Make sure the bed is well-drained as most herbs prefer or even require this and many will not thrive in heavy and certainly not even slightly waterlogged soil. You can do this by mixing in plenty of grit, sharp sand and/or perlite. I like the idea of a Bay tree at the back. They are slow growing so won't take over. Rosemary is also evergreen and lives quite a while if it is happy with soil conditions. Sage has lovely blue flowers and can also last for several years if cut back when it gets leggy. Bees go crazy for any of the thymes. Oh, and if you like basil, there are lots of varieties with coloured leaves which can be very decorative planted at the front, but are annual and die at the first hint of frost.
