Take very seriously everything that sysbee has advised you to do. Wildgrown seed and rootlets have performed very well and I would put them up against any that are on the internet. The one thing that I would caution you about is storing seeds or rootlets. You are asking for possible trouble if you have to go this route. Try your best to be free on the day they arrive and get to the job immediately. The quicker, the better. That in it's self is the best advise that I can give to you.
I went to the mountains this morning and took pictures of plants that are starting their 4th year. If you choose good spots to plant in this will be the results you will get with Wildgrown seed.
Three prong plant starting on it's 4 the season.
