How to tell it
A five-pointed white flower with a yellow cone centre, like a tomato's but small. Green berries turning glossy black, in hanging clusters. A soft plant with no spines.
What it is confused with
No dangerous lookalikes known in the Iberian Peninsula.
What it is for
None here. There are parts of the world where varieties of this species are eaten cooked, but European populations contain unpredictable amounts of solanine, especially in green berries. Not a plant for experiments.
