In Cypress you can figure out when it's a good idea to plant primroses by referring to the USDA zone info.

The last month that you can plant primroses and expect a good harvest is probably October. You probably don't want to wait any later than that or else your primroses may not have a chance to fully mature. Starting your primroses indoors is a great way to get them started a little bit earlier.
