Bottle gentian is a stunning native wildflower that produces deep blue, closed-bottle-shaped blooms in late summer and fall, making it a standout in shade or woodland gardens. It requires consistently moist, acidic, humus-rich soil and does not tolerate drought or heavy clay. This plant can be finicky to establish but rewards patient gardeners with striking, long-lasting color and excellent pollinator value.
