It has 3 brown paper-like spathes (leaves of the flower bud), that are reddish at the base, measuring between 3 to 5 cm long. The flowers come in a range of blue shades. From violet-blue, to blue, and occasionally white. The flowers are 6 to 7 cm in diameter. It has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. The drooping obovate falls, measuring 5 to 7.5 cm long and 2 to 2.5 cm wide, have a wide (or flaring) white blade or signal (central part of the petal) with dark-blue to violet veining.
