The Sun Berries also known as Wonderberries, taste like a mixture from elder and blueberry.
Solanum Burbankii was developed by plant genius Luther Burbank in the early 1900s.
An interesting tomato relative. 3' plants yield dozens of clusters of dark, 1/4" berries, and each cluster holds 8-12 fruits. Unique flavor, like elder and blueberry makes for intriguing dessert fillings, jellies, syrups, etc.
The berries are edible when they have turned from green to black. Very easy to sow and cultivate with an abundance of berries. Allow berries to fully mature.
