This plant is growing successfully at the Connie Hansen Garden in Lincoln City, Oregon, on the Central Oregon Coast. It is in a garden area that includes a lovely heather garden. It is blooming well right now after a rugged winter here on the coast.

Gentians are long-lived perennials
that thrive with little care. Plants
seldom need division and dislike root
disturbance.

Provide shade from hot afternoon sun
to avoid leaf browning,especially in
warmer zones.
