In Sheldon you can figure out when it's possible to plant geum by checking out the USDA zone info.

Planting Calendar for Geum

Frost tolerance for geum:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Geum tend to make it in a tiny bit of cold which means that you can plant them slightly earlier in the year than plants that are more sensitive to the cold.

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

The last month that you can plant geum and expect a good harvest is probably August. You probably don't want to wait any later than that or else your geum may not have a chance to fully mature. If you are starting your geum indoors then you might be able to get away with starting them a couple of weeks earlier.
