This picture of Gentiana andrewsii is posted for comparison to the Soapwort Gentian posted earlier. This attractive plant often grows in aspen thickets on damp, sandy soil. Compared to Soapwort Gentian, this plant has darker blue flowers that are more tapering into the summit, and this plant tends to grow 2 or 3 times taller. I'm sure that someone who never leaves their lab (and has never gotten their feet muddy or received a mosquito bite) has renamed it, but it is Gentiana andrewsii and always will be. I have a very large botanical library that says it is G. andrewsii.
