The multi-colored Deutzia is a 2 to 3 meter high, emerging shrub . The branches carrying flowers are brownish, 5 to 15 centimeters long, loosely star-haired and usually two to four-leaved, rarely six-leaved. The leaves have a 3 to 6 millimeter long stem. The leaf blade is simple, oblong-lanceolate or oval-lanceolate, 5 to 10 centimeters long and 2 to 3 centimeters wide, pointed, with a wedge-shaped to broadly wedge-shaped base and a finely serrated edge. Five or six pairs of nerves are formed. The upper side of the leaf is greenish and covered with four to six-pointed star hairs; the underside is greenish gray and densely covered with ten to twelve-pointed star hairs. On both sides, especially along the leaf veins, some have an additional central hair.

The inflorescences are 6 to 10 centimeters long, loose, hemispherical umbels with 12 to 20 flowers . The flower stalk is 1 to 1.5 inches long. The flower cup is 3.5 to 4 millimeters in diameter, 3 to 3.5 millimeters long and densely covered with ten to twelve-pointed star hairs. The calyx tips are the same length or slightly longer than the fruit cup and are oblong-lanceolate. The petals are white, oval, 10 to 12 millimeters long and 5 to 6 millimeters wide. The outer stamens are 5.5 to 7 millimeters long, the inner 3.5 to 5 millimeters. The stamens are pointed and two-toothed, with the teeth not reaching to the anthers. The anthers are stalked and ovate to rounded. The three or four styles are the same length or slightly longer than the stamens. The capsule fruits are brown, hemispherical and have a diameter of 4.5 to 6 millimeters. The calyx tips remain bent back on the fruit. The different colored Deutzia blooms from June to July, the fruits ripen from August to October.
