| It looks very similar to Solanum pseudocapsicum, Jerusalem or winter cherry. This is a rather tender perennial, frequently sold as a houseplant in colder climates, that is often seeded by birds in more southerly areas. All parts of the plant are poisonous, so I'd hesitate to make taste tests to see just how much like watermelon it is - small amounts ingested will cause just gastrointestinal upset. You would have to eat quite a bit to have truly toxic effects. |
