It's probably not a good idea to plant crossandra until after the last frost because they are not cold tolerant.

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