Parijat Tree located at Kintur village near Barabanki (Uttar Pradesh) is the only one of its kind in the entire country (apart from a different sub-species in Madhya Pradesh), and if you trust the locals and the legends related to the place, the only one in the entire world too. It's also known as Kalpavriksha, which basically means that it fulfills any wish or desire that you may have.
