|Gentiana 'True Blue'|
This is now in full bloom, and as you can see the bloom is very abundant indeed. And it has turned out to be easily grown. It's been in full sun - or as close as this garden comes to full sun - all season, so that answers the question about its sun tolerance. But does it need full sun? When I bought it, I had it in mind for a shady late fall border with Tricyrtis. But it's not even fall yet, and both the gentian and the toad lilies have been in bloom for weeks. Will there be anything left when autumn actually arrives? It looks as if that border I imagined will be a late summer border.
