Since santolina do well in cold you can plant them quite a bit earlier in the year than more sensitive plants.

The last month that you can plant santolina and expect a good harvest is probably August. You probably don't want to wait any later than that or else your santolina may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your santolina indoors.
