      Thanks for contacting. You can try, but what I’ve noticed is that plants, especially wild mountain plants, prefer outdoor growing conditions to indoor conditions. And, the sun is free energy.

      SE SC zone 8 b, will it survive summer heat and occasional winter frost? I want to grow in container. How deep, what height of container should 8 select? Will it truly take 6 years for the 1st harvest? Many thanks

      Osha (Ligusticum porteri) is far more adaptable than has been previously reported. If you want a really good rundown on it, check the OSHA chapter in my book “Growing At-Risk.” I haven’t seen it work particularly well as a potted specimen, though. It wants a deep, slightly acidic soil with a deep layer of carbon-rich mulch above. This is not a real easy plant to grow, it will survive in a Z 8 and it does take a long time to develop a usable root–that’s why its rare.
