Astilbe japonica

Astilbe japonica is a species within the genus Astilbe, which comprises about 14 species of herbaceous perennials in the family Saxifragaceae. Native to eastern Asia and North America, Astilbe plants are cultivated for their distinctive, featherlike flower spikes that appear in various colors, including white, yellow, pink, magenta, and purple, typically blooming in mid- to late summer.1

A. japonica, specifically, is known for its dense flower spikes and is sometimes referred to as florist's spirea. It can have variegated leaves and larger flowers compared to other Astilbe species. The name Astilbe itself is derived from Greek roots meaning "not sparkling," a somewhat ironic description given the plant's showy blooms.12
