In Page you can estimate when to plant centaurea by referring to the USDA zone info.

Planting Calendar for Centaurea

Centaurea do well in moderate cold which means that you can start planting them earlier than other plants that might not handle the cold.

The earliest that you can plant centaurea in Page 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 centaurea and expect a good harvest is probably September. Any later than that and your centaurea may not have a chance to grow to maturity. Starting your centaurea indoors is a great way to get them started a couple of weeks earlier.
