Common Names and Etymology

Ehretia microphylla is known by several common names, including Small-leaved Ehretia, Japanese Ehretia, and Korean Ehretia. Its scientific name honors the German botanist and physician, Georg Ehret. The specific epithet 'microphylla' comes from the Greek words 'micro' meaning small and 'phyllon' meaning leaf, referring to the plant's small leaves.

Ehretia microphylla is a multi-stemmed shrub that typically grows up to 3 meters (10 feet) tall, but can reach up to 6 meters (20 feet) in its native habitat. It has small, ovate leaves that are arranged oppositely along the stems. The leaves are glossy, dark green above and paler below, with a leathery texture. In late spring to early summer, the plant produces clusters of fragrant, white to cream-colored flowers at the tips of the branches. These flowers have five petals and give way to small, round, black berries in fall.

Habitat and Distribution

Ehretia microphylla is native to the temperate regions of East Asia. It grows naturally in forests, along streams, and on roadsides at elevations ranging from sea level to 1,500 meters (4,900 feet). It prefers well-drained, moist soils and partial shade, but can tolerate full sun and a range of soil types.
