I have lots of lavender growing. Also Italian and curly leaf parsley. The former self seeds very well (do note that parsleys are biennial so dies after the 2nd year when it seeds). Rosemary grew well but got really thrashed by heavy snowfall this year. Otherwise it's fairly hardy. Marjoram grows good, as does chive, lovage, sage (bit too strong smelling), tarragon and various mints. Thyme just seems to hang in there. The lovage has to be be dried early as the flavour gets too strong.

I second being careful with mint in the garden. It can become invasive quickly by seed or roots.

Not having much luck with basil the past few years. Might want to pot a thai basil that's a perennial and bring it indoors in winter.

Just hope that your climate will let your cilantro grow slowly, or it'll bolt into coriander. The trick apparently is to grow/seed every week or two if you want lots of cilantro leaves.

Do note that you can get a different type of chive allium (onion family) that survives mild winters. The normal chives die back in the autmun (or you can put it in a pot and bring it indoors).

As for slugs, you can always put a copper ring around your herbs. They seem to leave mine alone w/o any aid.

p.s. anyone wanting lavender seeds, give me a holler. I have lots.
