Man's ear rings form on the ends of branches and winter in the form of well noticeable dense dark brown ear rings, to-rye spring begin to grow, at the same time numerous covering scales are moved apart, baring 3 flowers consisting of two stamens with yellow boots, two bracts and hardly noticeable perianth.
