About plant names...

Bottle gentian is a North American native plant.

Identification: Plants are 12-24" (30-60 cm) tall. One or more round, hairless stems emerge from the ground, green or purple. Leaves are opposite, sessile, lanceolate to ovate, up to 4½" (11 cm) x 2" (5 cm). They are shiny, and have roughly parallel veins. At the top of the plant, the leaves form a whorl. Flowers are blue-violet (sometimes white, pale blue, or pink), and look like buds on the verge of opening, because they never fully open. Each flower is 1-1½" (2.5-3.8 cm) tall and up to ½" (1.3 cm) in diameter. They are often described as bottle-shaped, and appear from July to October. The fused flowers dry out, becoming a papery wrapper for a one-inch capsule with seeds.
