Gentiana asclepiadea is a species of flowering plant of the genus ''Gentiana'' in the family Gentianaceae, native to central and eastern Europe.
Hundreds of upturned deep blue trumpets on arching stems with willow like leaves bloom through summer and into late autumn. The easiest, longest lived, latest flowering and most rewarding of the taller gentians. Requires partial or full shade and moist soil.
Gentians are long-lived perennials that thrive with little care. Plants seldom need division and dislike root disturbance. Zone 5-7.
