By referring to the USDA zone info for The Colony you will be able to estimate when you can plant primula.

Planting Calendar for Primula

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

Primula are very cold tolerant which means that you can start planting them much earlier than other frost tender plants.

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