Flowers are born in fan-like terminal clusters atop erect, pubescent stems. They consist of three yellow inner tepals and three outer petals that are creamy white and covered in soft wooly hairs. Stamens are prominent. Anthers are yellow to rusty orange. Leaves are flat, lanceolate and become reduced in size as they ascend the stem. They are alternately arranged. The leaves give the plant an iris-like appearance before it blooms.
