Lysimachia do well in a little bit of cold which means that you can plant them a little earlier in the year than other frost tender plants.

The earliest that you can plant lysimachia in Alpine 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 lysimachia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your lysimachia may not have a chance to really do well. Starting your lysimachia indoors is a great way to get them started a few weeks earlier.
