Between two and ten or more pale blue to mauve or pink flowers 20–30 mm (0.8–1 in) wide are arranged on a flowering stem 100–700 mm (4–30 in) tall. The sepals and petals are 10–15 mm (0.4–0.6 in) long and 3–8 mm (0.1–0.3 in) wide. The column is white to pale blue or pale pink, 5–7 mm (0.2–0.3 in) long and 2–4 mm (0.08–0.2 in) wide.
