How to Grow Sapphireberry — Symplocos

Sharing is caring!

Symplocos–commonly called sapphireberry–is a large deciduous shrub or small tree that is often grown for its panicles or racemes of yellow or white flowers that appear in spring followed by blue, black, purple, or white berry-like fruits in autumn.

There are about 250 species in the Symplocos genus, but only one, S. paniculata, is generally grown in gardens for its flowers and fruit. It is a showy addition to a shrub border.

Symplocos produces the most autumn berries when several plants are planted together. The berries make a spectacular garden accent.

Symplocos is native to woodlands in North and South America and is also found from East Asia to Australasia.
