Calycanthus is often grown ornamentally. Also in cultivation is Chimonanthus praecox (Linnaeus) Link, an eastern Asiatic shrub. Chimonanthus differs from Calycanthus in its scaly buds and yellow flowers that appear long before the leaves.
Calycanthus contains calycanthine, an alkaloid similar to strychnine, and it is toxic to humans and livestock (W. H. Lewis and M. P. F. Elvin-Lewis 1977) .
