Bottle Gentian (Gentiana andrewsii)

Bottle Gentian (Gentiana andrewsii)

The bottle-shaped flowers are a consistent head-turner in gardens, whether it’s the deep blue shade of their flowers, the glossy texture of their leaves, or their late summer bloom window when many other flowers are long gone. Long-lived and won’t spread. Great for rain gardens.
