About
Solanum retroflexum, commonly known as umsobo (isiZulu), wonderberry or sunberry, is a historic heirloom fruiting shrub. Both common names are also used for the 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 species S. scabrum described by Philip Miller.
The plant produces diminutive, dark blue-purple edible fruits that are bland in flavor and often combined with sugar in desserts. Green (unripe) fruits may be poisonous.
How to grow it
The wonderberry shrub is an easy-to-grow plant which is grown similarly to tomatoes. Seeds are sown in the summer in full or part sun. Fruit can be expected in 75 days.
