Its strongly scented pendent flowers, produced in winter (between November and March in UK,) on bare stems, have 15-21 yellow or pale green-yellow, tepals, the inner ones usually with purplish red pigments.This plant is cultivated in gardens, producing valued flower colour in the dormant season. The varieties C. praecox 'Grandiflorus'and C. praecox 'Luteus' have gained the Royal Horticultural Society's Award of Garden Merit.The plant is unrelated to allspice (Jamaica pepper), and not only is it not edible, but its seeds contains a toxic alkaloid called calycanthine.
