Gentiana andrewsii (Bottle Gentian)

Best grown in moist, rich, acidic, well-drained soils in part shade. Dislikes hot nights. If left undisturbed, plants in optimum growing conditions will naturalize over time into large clumps. Typically grows one to two feet tall. The name comes from its tight clusters of tubular (bottle-shaped), deep blue flowers which never open. Flower clusters appear at the tops of the stems or in the upper leaf axils in late summer to early autumn. Ovate, lance-shaped leaves to four inches long have parallel veins.
