(Bear Medicine) Perennial herb native to the Rocky Mountains. Traditional usage (American Indian, TWM): upper respiratory infection, cough, altitude sickness. Plant prefers full sun to part shade and is often found in association with aspen groves. Sow in outdoor conditions in flats or in nursery bed. Sow seed about 1/4 inch deep and cover with soil, tamp well, then cover the planting with a thin layer of organic mulch such as rotted sawdust, peat or coir. Sow in cool soils in outdoor conditions. Best to sow in the fall for germination in the spring. For an in-depth discussion of seed germination and cultivation of Osha, see the Osha chapter in the book “Growing At-Risk Medicinal Herbs.” Thin seedlings to 6 inches apart and keep well-weeded and deeply mulched.

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.

Hi, do you know if the above ground parts have decent medicinal value, or is it only the roots?
Thanks 🙂

Good question. The seeds have definitely been used as a condiment and stomachic. I am not so sure about the leaves, but think they would be OK, perhaps a mild version of our smoky and oily root. r

Hello, How is your osha seed this year? Is there still some fresh seed available ? I want to try germinating some again during upcoming vernalization.
I was wondering about another species of linguisticum that I came across called ‘scotium’ or Scot’s lovage. Maybe a European species?
It is referenced as a medicinal, but is supposedly an easy germinator.

Hello Ian,
Its a good year on osha (Ligusticum porteri), and the harvest was made only 30 days ago, it is as fresh as it gets. Right, L. scotium is from the place that its species name implies–Scotland and thereabouts.
