Since artemesia are one of those plants that can tolerate a tiny bit of cold weather you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant artemesia in Richardson is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant artemesia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your artemesia may not have a chance to fully mature. You can get started a few weeks earlier by starting your artemesia indoors.
