Spiraea lucida

Spiraea lucida, the shiny-leaf meadowsweet, is a species of flowering plant in the family Rosaceae, native to western Canada as far as Saskatchewan, and the northwestern United States as far as the Dakotas.^[1][2] In the past, due to its leaf morphology varying greatly because of the plants' tendency to die back to the ground in winter, it was considered a variety of Spiraea betulifolia, the white or birch-leaf meadowsweet.^[2]
