This orchid blooms in summer and autumn, showing rather open clusters of showy terminal flowers, ten at the most. They bloom in succession on the terminal racemes,which are 7 to 16 cm long. These flowers, 5–8 cm in diameter, are a rosy lilac and white disc with a purple lip. The bracts are broadly triangular and surround the main stalk of the flower cluster. The occasional fertilized seed pods contain minute powdery seeds, and small plants often develop near the cane ends after flowering, which likely aid in propagation if allowed to reach the soil.
