Hi Margaret, This is an interesting herb I have just recently learned about and was surprised to see it in the Richters catalog that I just got. I was under the impression that people were still researching how to germinate it. I also thought that it had to be grown at a high altitude? 8000ft? This is all from memory of reading an excerp from an herb book. It I find out more I will let you know. Jane > > Has anyone had success germinating the herb osha (Ligusticum porteri)?

Could this be the problem with osha? > Richter's says it "probably needs" cold stratification. TIA, Margaret L
