Thladiantha dubia is characterized by its ovate-cordate, unlobed leaves; relatively large, solitary flowers with narrow, recurving sepals, campanulate corollas, yellow petals, usually with recurving apices; and pendulous, hirsute-villous, orange-red fruits. It is grown as an ornamental, especially for its large, bell-shaped flowers and brightly colored fruits. Few populations are apparently outside of cultivation at present, but even staminate plants are potentially invasive because of the spread by tubers.
