Ukraine’s traditional midsummer celebration, associated with bathing and wreaths, is called Ivan Kupala. The name combines Ivan, a form of John, with Kupala, a traditional Slavic seasonal figure or festival name.
Ivan Kupala customs commonly include bonfires, jumping over flames, bathing or ritual washing, singing, and floating wreaths on water. Young people may use the movement of a wreath to tell fortunes, while older folklore connects the night with fertility, love, and the search for a magical fern flower.
The celebration has both pre-Christian seasonal elements and Christian associations with the Nativity of John the Baptist. In the modern Gregorian calendar, Ukraine traditionally observes it on the night of July 6 to 7, although calendar reforms and regional practices can affect public observance.
Ivan Kupala is related to Polish Noc Kupały and other Slavic midsummer traditions, but the names and local customs are not interchangeable. The legendary fern flower is a folklore motif, not a botanically observed flower.
