Partial shade.Īmerican spurred gentian is often encountered in moist woods on trails that are wide enough to allow some sunlight to filter through. The inflorescence is a racemose cyme bearing 5 to 25 flowers, approximately 1/2 to 3/4 inches across. Coniferous forests, especially at the edges cedar swamps bogs river banks road clearings and trails. Green to yellowish, often tinged with purple The fruit is a cone-shaped, curved, seed capsule that protrudes horn-like beyond the persistent corolla at maturity.

There are 4 sepals, 4 petals, 4 stamens, and 1 style. Each flower is at the end of a stem that is up to 1 ½ ″ long. The inflorescence is a loose, branched, cyme-like cluster of 2 to 9 flowers, usually 5 or more, at the end of the stem and also rising from upper leaf axils. The upper and lower surfaces are hairless. Stem leaves are opposite, lance-shaped to egg-shaped, unlobed, ¾ ″ to 2 ″ long, ⅜ ″ to 1 ″ wide, and stalkless. It is usually unbranched but sometimes has a few branches above the middle.īasal leaves are spatula-shaped or inversely lance-shaped, 2 ″ to 4 ″ long, and narrowed to a short stalk.
