Boechera missouriensis is an erect biennial. It produces racemes of small creamy-white flowers in the spring.[7][5] It bears a resemblance to more widespread Boechera laevigata, from which Boechera missouriensis can be distinguished by the following characters: Stem leaves dense, erect, and overlapping, basal leaves persistent and pinnately lobed, petals about twice as long as sepals, and stems often red-tinged.[5][1]
