Aubretia do well in cold which means that you can plant them much earlier than more sensitive plants.

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