Since gazania do ok in moderate cold you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

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