Some of the popular common names of the plant are Jacaranda, Xicranda, Brazilian rose wood, Black poui, Blue Jacaranda, Jacarand, green ebony, mimosa-leaved jacaranda, mimosa-leaved jacaranda, Fern Tree and sharp-leaved jacaranda. Older sources call it Jacaranda acutifolia, but it is nowadays more usually classified as Jacaranda mimosifolia.
