Are Lobelia species interchangeable? Specifically, Lobelia kalmii: aka Kalm’s Lobelia aka Ontario Lobelia aka Brook Lobelia is growing profusely along the river’s edge of a rocky island in Lake Huron, MI. USA
There are a number of Lobelia species that have quite different chemistry. I can’t find much info on L. kalmii. I’d stick with L. inflata or L. cardinalis. THey have the most data.
