Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Boston you can figure out when you can plant gazania by referring to the USDA zone info.

Frost tolerance for gazania:	Tolerant of a very small amount of frost.

Gazania tend to make it in a tiny bit of cold which tells us that you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant gazania in Boston 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 gazania and expect a good harvest is probably August. If you wait any later than that and your gazania may not have a chance to really do well. You can get started a little bit earlier by starting your gazania indoors.
