The pride and decoration of the Plateliai Manor Park is Ash of the Witch – the thickest ash of Lithuania. Its trunk volume at 1.3 m height is 7.3 meters.

Several stories are known about this unique tree. According to one of them, in ancient times, witches and devils used to misled people to take away goods from them. Once there was one incident with the village woman, who was going home late at night and witches misled her. The woman was running around the Manor Park, thinking that she was in the forest which is unfamiliar to her. She was wandering around until she got tired. Then he sat down under the ash-tree to take a rest and fell asleep. At that time, the witch grabbed her loaf of bread and wanted to eat it, but the cocks started to crow… Then a witch got angry and crashed a loaf of bread into the tree, which turned into a knot… And the tree was called by people as the Ash of the Witch. Some are saying that the devil tried to fold four ashes together and they became as one trunk some day. Others claim that the woman strapped three bewitched trees with her headscarf on which birds were not perching. Those trees grew up together, and even the mark of the headscarf’s knot is present. Others still claim that the witches are still visiting this ash and they gather together here at night in order to talk things over. After the meeting, they are flying to the Šatrija Hill.
Horse chestnuts, black locusts and common lilacs have also survived as exotic plants. In the eastern part of the forest stand, which surrounds a large pond and is like a natural grove, spruces, pine trees and white willows are growing. The northern part of the park alley is planted with small-leaved lindens, and the alley of the southern edge – with maples and horse chestnuts. The narrow forest stands with devious contours, surrounding small irregular spaces, are formed from the maples, oaks, ashes, rowans and hornbeams.
