It typically forms a sempervivum-like basal rosette of thick fleshy oblong lavender gray leaves (to 1″ long by 1/2″ wide). Each basal rosette typically matures to 4″ tall but spreads outward to 12″ wide by offset plantlets which radiate from the leaf axils of the main rosette by thin, stolon-like branchlets. Tiny yellow flowers appear in spikes rising from the rosette to 6″ tall. A rosette usually flowers in the second or third year. Each spike is cone-shaped and resembles a dunce’s cap, hence the common name. The flowering rosette dies after producing flowers but the younger offsets that have yet to produce flowers remain. Rosettes that have not bloomed wither in fall, but grow back in spring.
