Since oenothera are moderately cold tolerant you can plant them just a bit earlier in the year than other plants that might not handle the cold.

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