The Ukrainian Christmas decoration made from a sheaf of wheat is called a didukh.
A didukh is formed by gathering wheat stalks—traditionally among the first or last harvested during the year—and tying them with thread, ribbons, or other decorative materials. Its name literally means “grandfather spirit,” reflecting its connection with family ancestry and the continuing presence of departed relatives.
The decoration represents the autumn harvest and expresses hopes for abundance, household prosperity, and a bountiful year ahead. Traditionally, it is brought into the home before Christmas and kept there through the holiday season, in some accounts until Masnytsia, the pre-Lenten festival.
Didukh is sometimes confused with other Ukrainian cultural terms. A pysanka is a decorated Easter egg, kutia is a traditional Christmas Eve wheat dish, and vertep is a nativity puppet theatre or performance. The sheaf itself is the didukh.
