Wonderberry (Solanum retroflexum previously called Solanum x burbankii), also known as Burbank’s Sunberry and Garden Huckleberry, is a small, berry producing plant in the Tomato Family (Solanum) developed by renowned American plant breeder Luther Burbank in the early 1900s.

The Wonderberry grows as a bushy, erect shrub which reaches on average a height of 12 and 24 inches but may fruit at sizes as small as 4 inches in height.

Plants produce clusters of small round berries about the size of blueberries and will turn from green to a velvety black-blue when ripe. Wonderberries have a juicy interior and offer a soft texture and mild, slightly sweet flavor when ripe. Wonderberries are excellent as a jam, jelly or pie filling. Green unripe berries may be toxic. To be safe only consume Wonderberries when they are fully ripe and blue-black in color.

The Wonderberry, also known as the Sunberry, was originally botanically classified Solanum burbankii and today is classified as Solanum retroflexum. The fruit was created by renowned American plant breeder, Luther Burbank prior to 1909 when he crossed Solanum guinense of West Central Africa with Solanum villosum of Chile. Wonderberry bears a close resemblance to the garden huckleberry (Solanum melanocerasum) but is, in fact, a separate species.
