When to plant:	Up to 3 weeks before last frost.

Bacopa are barely cold tolerant which means that you can plant them slightly earlier than plants that are more sensitive to the cold.

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