Overview
The Japanese snowbell, Styrax japonicus, is a small deciduous tree in the storax family (Styracaceae), prized for its delicate, fragrant flowers. In late spring to early summer, rows of pendulous, bell-shaped white flowers with yellow stamens hang in lines beneath the wide-spreading branches.
The tree grows 20-30 ft (6-9 m) tall, often with a broad, layered, horizontal branching pattern that displays the dangling flowers beautifully when viewed from below.
Smooth gray bark and clean foliage make it an excellent small specimen or patio tree, especially where it can be underplanted and admired from beneath.

Habitat & origin
Styrax japonicus is native to Japan, Korea, and China, where it grows as an understory tree in moist woodlands and along forest edges and streams.
It is widely planted as an ornamental in temperate gardens of Europe and North America, valued especially in small gardens, courtyards, and as a patio or lawn specimen where its hanging flowers can be appreciated from below.
Uses & benefits
Ornamental: Grown for its elegant horizontal form and dainty hanging flowers; ideal as a small specimen, patio, or courtyard tree.
Ecological: The fragrant flowers attract bees and other pollinators.
Practical: Some Styrax species are sources of the aromatic resin benzoin (used in incense and perfumery), though S. japonicus is grown chiefly as an ornamental rather than for resin.
