Gentiana asclepiadea

Willow Gentian

Gentiana asclepiadea, known as the willow gentian, brings an enchanting touch to the garden with its graceful, arching stems and deep blue to purple, trumpet-shaped flowers. Blooming from late summer into early fall, these blossoms appear in clusters along the stems, providing vibrant color when many other plants are winding down. The intense blue hue is a refreshing sight, adding richness to mixed borders and shaded areas.
