Aquilegia ballii is a perennial herb growing to high. The rhizome is thick and covered with the remains of previous years' foliage. The stem is robust, smooth, and branched towards the top; the branches may be pubescent or glandular. The basal leaves are green on their upper surface and pale green on the underside, biternate or triternate (i.e. with three stalks, each with three leaflets that divide into three lobes), and have pubescent leaf stalks up to long. The flowers have white or slightly bluish sepals long and white petals long with blue, slightly curved nectar spurs of length. Both the sepals and petals are green at the tip and sparsely hairy. The anthers are bright yellow.
