Planting order
When each one first goes in around Portland, starting indoors where that comes first. Colder towns run later.

Growing herbs in the Northwest
Herbs fall into two camps. Mediterranean perennials such as rosemary, thyme, oregano and lavender want full sun and sharp drainage, and in Northwest gardens it's winter wet, more than cold, that kills them. Plant them in a raised bed, a container or a gravelly, sloping spot, and go easy on fertilizer and water once they're established.
Leafy annuals are the other camp. Cilantro and dill grow well in cool spring weather but bolt quickly in summer heat, so sow a little every few weeks. Basil is the opposite: it needs warmth and suffers when nights are cool, so it's one of the last things to go out. Parsley sits in between and is happy from spring into winter in mild areas.
Mint spreads aggressively by underground runners, so keep it in a pot. Chives are the easiest place to start: a perennial that comes back every spring, takes partial shade and needs almost no care.
Common questions
Which herbs come back every year in the Northwest?
Chives, mint, oregano, thyme, sage, tarragon, lemon balm and lavender are perennial here. Rosemary survives most west-side winters in well-drained soil. Basil, cilantro and dill are annuals.
Why do my rosemary and thyme die over winter?
Usually wet, cold soil rather than cold air. Mediterranean herbs need sharp drainage, so grow them in raised beds, on a slope or in pots.
When can I plant basil outside?
Not until nights stay warm, usually late May or June. Basil is damaged by temperatures in the 40s, so it's one of the last herbs to go out.
