It is about ¾–1½' tall, with bright blue to deep blue-violet bell-shaped, upright, five-lobed flowers measuring 1½ to 2¼ inches across when fully open. Flowers grow in clusters of 1–8 at the apex of the plant. Lanceolate, sessile, glossy leaves up to 3" long and 1¼" across are arranged oppositely along the central stem, except at the apex where they grow in whorls of 3–7. Gentiana puberulenta grows in dry upland prairies and woods and rocky open slopes.
Downy gentian is fairly disease-resistant and generally not prone to illness. However, it can be susceptible to pests and diseases present in its surroundings. These infections are typically mild. For care, this plant requires moderate maintenance. It should be pruned regularly to maintain a good appearance and healthy growth. Fertilizing can also help encourage flowering. Downy gentian is suitable for anyone with an outdoor area, such as a garden or patio, and does not need extensive care experience. It may need more attention when grown indoors.
