Since artemesia are barely cold tolerant you can plant them just a tiny bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant artemesia and expect a good harvest is probably August. If you wait any later than that and your artemesia may not have a chance to grow to maturity. If you are starting your artemesia indoors then you might be able to get away with starting them a little bit earlier.
