One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of making a decision about when you can plant sedum is to use the USDA zone info for Marion.

When to plant:	Up to 7 weeks before last frost.

Since sedum do well in cold you can plant them quite a bit earlier in the year than other frost tender plants.

The earliest that you can plant sedum in Marion 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. If you wait any later than that and your sedum may not have a chance to fully mature. If you are starting your sedum indoors then you might be able to get away with starting them a couple of weeks earlier.
