Deutzia crenata is a species of flowering shrub in the hydrangea family (Hydrangeaceae).

[3] It has been commonly cultivated outside its native range, and has naturalized from plantings in China and North America.

In contrast to the similar Deutzia scabra, its leaves are not notably diamorphic and are found on short petioles throughout the length of the stem.

In addition, all of the filaments of Deutzia crenata are toothed.

[3] A form with doubled flowers (forma plena) is popular in gardens.
