Silphium wasiotense is an erect herbaceous perennial. It has large, toothed, persistent basal leaves, and similar cauline leaves which are reduced in size up the stem. Silphium wasiotense can be distinguished from the similar looking Silphium brachiatum and Silphium mohrii by its combination of cordate to subcordate leaf bases and hispid stem.[5] It produces yellow flowers in late summer and fall.[4]
