In your 2002 catalogue you offer Chinese Rhubarb (Rheum palmatum) in dried root form but not the seeds, although you do offer Roundleaf Da Huang seeds. Is it possible to get the seeds for this herb?We are conducting trials on various medicinal rhubarbs from China and Tibet. We hope to be able to offer seeds or plants of the true da huang within a year or two. But true da huang is proving to be very difficult to source. Part of the problem is that the Chinese themselves are imprecise about what botanical species is meant by "da huang". For sure, we know that several different species are used as "da huang". Every supposedly authentic seed lot from China that we have tried to date has proved not to conform with the Rheum palmatum or R. tanguticum forms (with palmate leaves).
