Before planting it is a good idea to find your USDA Zone info to determine 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 Wyoming you can estimate when it's possible to plant sedum by reviewing the USDA zone info.

Planting Calendar for Sedum

Frost tolerance for sedum:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Sedum are very cold tolerant which tells us that you can start planting them much earlier than other plants that might not handle the cold.

The earliest that you can plant sedum in Wyoming is February. However, you really should wait until March if you don't want to take any chances.

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

Last Frost Date

The average date of last frost is April 15 in Wyoming. It might get as low as -15°F during the coldest months of winter.

Remember that USDA zone info for Wyoming is an average and the actual date of last frost is different every year. Half of the time in Wyoming it frosts late in the year after April 15 so be sure to be ready to cover your sedum if you have a late frost.
