Help me to identify this plant with thorn leaves
This is Solanum pyracanthos, also known as the Porcupine Tomato, is an evergreen shrub native to tropical Madagascar and the islands of the western Indian Ocean. The plant contains various toxic tropane alkaloids in its leaves, stem and fruit and therefore should be considered dangerous to humans.
This species is part of the same extensive genus that includes such plants as the potato, tomato, and nightshade. The species propogates slowly, since birds do not consume the fruit, thereby spreading the seeds.
Despite its toxic nature, the Porcupine Tomato is a popular ornamental plant.
