Solanum retroflexum

"Sunberry", "Wonderberry" and variant spellings redirect here. These names are also used for a related plant that may be highly poisonous; see below for details.

Solanum retroflexum, commonly known as wonderberry or sunberry, is a historic heirloom fruiting shrub. Both common names are also used for the sometimes poisonous European black nightshade (Solanum nigrum) in some places, particularly where the latter species has been introduced, so care must be taken to distinguish them. It is sometimes called garden huckleberry, but that properly refers to the S. scabrum described by Philip Miller.
