Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

By referring to the USDA zone info for Oregon it's a good idea to figure out when to plant sedum.

Planting Calendar for Sedum

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

Sedum do well in pretty solid cold which tells us that you can plant them earlier in the year than more sensitive plants.

The earliest that you can plant sedum in Oregon 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 grow to maturity. You can get started a couple of weeks earlier by starting your sedum indoors.

Last Frost Date
