Problem description:

Who knows that this "Osmunda japonica" and "The Book of Songs" also have the growth characteristics of bracken.

It is best to plant bracken in the northwest, whether it is annual or biennial, when to plant it, when to germinate, when to mature and so on. The finer the better! I just came to "know" that I didn't order much. I'll give you 20 points first! thank you
