Gentiana andrewsii var. andrewsii

Bottle gentian is a stunning native perennial known for its unique deep blue to violet closed flowers that appear in late summer and fall. It requires consistently moist, humus-rich, well-drained soil and partial shade, making it ideal for rain gardens, woodland edges, or streamside plantings. This species can be finicky to establish but is highly rewarding for experienced gardeners seeking a dramatic, pollinator-friendly fall bloomer.
