Gentiana calycosa Griseb.
Rainier pleated gentian
USDA Symbol: GECA
USDA Native Status: Native to U.S.
The clump of 4-8 in. stems is ever-increasing. Leaves are opposite, about 1 in. long, somewhat oval, and sessile to the stem. Several leafy stems in a clump bear at the top 1-3 blue, broadly funnel-shaped flowers. The light to deep blue, tubular flowers are held erect at the ends of the stems. The blue of the flower is sometimes mottled with green and the inner cup is pale.
Gentians are among the loveliest of mountain wildflowers and are rock-garden favorites. The genus honors King Gentius of Illyria, ruler of an ancient country on the east side of the Adriatic Sea, who is reputed to have discovered medicinal virtues in gentian plants.
