Since primula are very cold tolerant you can plant them much earlier in the year than plants that are more sensitive to the cold.

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