The inflorescences are 5 to 10 centimeters long and 3 to 6 centimeters in diameter, many-flowered zymous panicles . The flower stalk is 3 to 5 millimeters long. The flower cup is about 2.5 millimeters long with a diameter of 2 millimeters. The calyx lobes are egg-shaped, about 1.2 millimeters long, 1 millimeter wide and densely covered with yellowish brown star hairs. The petals are white, narrow-oval, 8 to 15 millimeters long and about 6 millimeters wide. The outer stamens are 8 to 10 millimeters long, the two teeth of the stamens are horizontal and do not reach the anthers. The anthers are stalked, elongated and grow between the teeth of the stamens. The inner stamens are shorter than the outer ones, the filaments are bidentate at the tip and rarely tongue-shaped. The three or four styles are longer than the stamens. The capsule fruits are hemispherical, loose star hair and have a diameter of about 4 millimeters. Deutzia crenata flowers from April to May, the fruits ripen from August to October.
