Taxonomy and etymology

Exochorda racemosa was first described by John Lindley. It is placed in the genus Exochorda and family Rosaceae, the rose family.[4] The plant gets its common name, "common pearlbush", from its pearl-looking flowers.[5]

A loose, irregular or vase-shaped and upright shrub, this species is deciduous. It has oblong leaves, about 4–6 cm (1.6–2.4 in) long and 1–2 cm (0.39–0.79 in) wide, that are rounded and toothed at the margin on the top. The flowers are white, and flower in late April to early May.[6] The flowers have round petals, 12-25 stamens, borne in racemes in groups of about six or ten. Their diameter is 4 cm (1.6 in).
