[Moderator note: Split from "Not Gentiana but Gentianella" thread.]
I do like G amarella too :) it often grows in similar places or even with another Gentian relative, Halenia- even more subtle in flower, but also an interesting and charming plant. I think the Gentianella includes more open places in its range than does the Halenia, they overlap in woodland edge/clearing kinds of habitat; Both grow naturally on my 6 acres, but not always in convenient spots,. so I hope to get some nice patches established once I have the right beds ready..
Here's one view of Halenia deflexa, I'll find more later- I don't suppose this is an important enough genus to bother with a new thread?
