The flowers of the white ash are not showy. There are two kinds, on different trees, the male in dense reddish purple clusters and the female in more open bunches. The fruit of the ash is winged, 1 to 1.5 inches long, resembling the blade of a canoe paddle in outline, with the seed at the handle end. The fruits mature in late summer and are distributed effectively by the winds. Only the female white ash bears fruit.
