Iris swensoniana has very small rhizomes. The plant can reach up to 20–45 cm (8–18 in) tall, normally about 40 cm. It has falcate (meaning cutlass-shaped) or very curved leaves, that are blue-green in colour. It has blooms which are 7–8 cm (3–3 in) in diameter. Like other irises, it has two pairs of petals: three large sepals (outer petals), known as the 'falls', and three inner, smaller petals (or tepals), known as the 'standards'. The upright standards are paler than the falls, in shades of light purple, or purple. The drooping falls are blackish purple, and in the middle of the petal is a signal patch which is even darker, in shades of dark maroon-black. The middle fall also has a row of tiny hairs called 'the beard' which are yellow tipped with purple, or black-purple. After the iris has flowered, it produces a seed capsule that has not been recorded.
