| Positive | On Aug 21, 2015, Ted_B from Birmingham, AL (Zone 8a) wrote: This shy plant survives in a shady location, in reasonably well draining soil with a healthy dose of hardwood leaf mulch and adequate moisture. It is most tolerant of full shade or a short dose of morning sun. It does not tolerate dry conditions for long periods. Once established, it tends to spread via runners, so look for new stalks emerging each season. |

| Positive | On Oct 26, 2007, creekwalker from Benton County, MO (Zone 5a) wrote: I have not found this plant growing wild in my woods, however, I did take a few plants from my parents land(they had large patches of it growing wild), a couple of hundred miles from me and transplanted it and it thrived. I had to transplant it again when I moved, but now it has a nice home in the woods. It survived the second transplant even. It seems to be fairly hardy and I hope it continues to do well and multiply. |
| Neutral | On Feb 10, 2006, HawaiiBill from Kea`au, HI (Zone 11) wrote: I've entered into an effort to cultivate goldenseal in Hawai`i. There are those who believe it needs a freeze but finding any authority for that is difficult. I would very much appreciate any notes on efforts to grow this root in a tropical setting. My come from a Southern state but, as you all know, it freezes in the Southeast regularly. |
| Positive | On Apr 27, 2005, DiOhio from Corning, OH (Zone 6a) wrote: It is also known as Yellowroot. It is dug and sold for medicinal purposes. I'm not sure what price it brings today but about 9 years ago it only brought about $15.00 per dried pound (that's a lot of dried root to make a pound !). |
