A common way of getting a good idea when it's possible to plant anise is to examine the USDA zone info for Sonora.

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

Since anise are one of those plants that can tolerate a tiny bit of cold weather you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant anise in Sonora 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 anise and expect a good harvest is probably September. You probably don't want to wait any later than that or else your anise may not have a chance to grow to maturity. If you are starting your anise indoors then you might be able to get away with starting them a couple of weeks earlier.
