The flowering scape is up to 270 mm (11 in) long clasped by a single, small leaf and the sheath enclosing the flowers is lance-shaped, glabrous, green and 32–60 mm (1.3–2.4 in) long. The outer tepals are pale violet to purple or blue, 15–24 mm (0.59–0.94 in) long and 12–20 mm (0.47–0.79 in) wide, and the hypanthium tube is 30–45 mm (1.2–1.8 in) long. Flowering occurs from August to October.[3]
