Flowerstalks emerge in September, months after the leaves have died back, giving rise to the names Naked Boys (in the U.S.) and Naked Girls (in Britain). In early fall, Colchicum’s large bulb-like corms send up cup- or goblet-shaped crocus-like 4-8" flowers, up to five per stem, in shades pastel to vibrant. Handsome glossy broad 8-12" leaves emerge in spring to feed the corms, then die back by late summer to make way for fall’s naked bloom.
