It grows as a broad, upright, bushy, finely branched shrub that reaches up to 1.5 meters in height. Flower-bearing twigs are brown, 5 to 17 centimeters long, glabrous, and typically bear four leaves. Each leaf has a petiole 2 to 4 millimeters long. The leaf blade is light green, simple, and shaped lanceolate, oval-lanceolate, or broadly ovate-lanceolate, measuring 3 to 4.5 inches long and 1 to 1.2 inches wide. Leaves have a long pointed apex, a wedge-shaped base, and finely serrated margins, with three or four pairs of leaf veins. The upper leaf surface is covered in three or four-pointed star hairs, while the lower leaf surface has four or five, rarely six-pointed star hairs. In cultivation, the compact cultivar 'Nikko' grows 1 m (3.3 ft) tall by 1.5 m (4.9 ft) broad, and has received the Royal Horticultural Society's Award of Garden Merit. The hybrid Deutzia × rosea, also classified as the synonym Deutzia gracilis 'Rosea', produces pink flowers matching its name.
