Often called "Closed Bottle Gentian," this plant is one of the most intriguing and beautiful additions to the late-season garden. Bottle Gentian features clusters of deep, true-blue flowers that look like oversized flower buds that are just about to open—but they never do! The petals remain permanently fused into a "bottle" shape.
Sun Exposure Partial Shade (Preferred) to Full Sun
Water Needs Moderate to High; prefers consistently moist soil.
Soil Type Thrives in moist Clay, Loam and Sand
Mature Height 1 – 2 feet
Deer Resistance High
Bloom Time August – October
Plant Spacing 1 – 2 feet
Color: Offers a stunning, glossy dark green foliage and vivid cobalt blue that remains vibrant even as the rest of the garden begins to turn brown in the fall.
Low Maintenance: Once established in a moist, semi-shaded spot, it requires little care.
Best conditions: Bottle Gentian does best in a moist, low-lying transition zone, such as a woodland edge or the edge of a shade garden. Blooming into the fall, it tolerates cold weather.
Black Walnut tolerant
Bumblebee Exclusive: Because the flowers never open, they require "specialist" pollinators. Strong bumblebees are the only insects powerful enough to pry the petals apart and crawl inside to reach the nectar.
Late-Season Lifeline: Since the nectar is "locked away" from other insects, it provides a dedicated food source for bumblebees preparing for winter.
Pest Resistant: Its unique flower structure protects the nectar and pollen from many common garden "thieves" and beetles.
Pro Tip: It is a great companion to other late bloomers such as: Prairie Blazing Star (Liatris pycnostachia), New England Aster (Aster novae-angliae) and Obedient Plant (Physostegia virginiana).
