By looking at the USDA zone info for Zone 8b you should be able to determine when to plant digitalis.

Planting Calendar for Digitalis

When to plant:	Up to 5 weeks before last frost.

Since digitalis are moderately cold tolerant you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant digitalis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your digitalis may not have a chance to really do well. Starting your digitalis indoors is a great way to get them started a few weeks earlier.
