Colchicine is a medication used to treat and prevent gout attacks and familial Mediterranean fever. It is also used in plant biology to induce polyploidy.
True to its name, it typically flowers in early to mid-autumn (September-October). The leaves appear in spring, die back, and then the flowers emerge without foliage in autumn, hence the name 'naked lady'.
