Litchi Tomato (Solanum sisymbriifolium)

A rare plant which comes from France, this relative of the tomato has some serious defenses, but the gorgeous white flowers and interesting edible fruit make it worth growing. The seed-filled red cherries are very sweet with a wild tang that can become addictive.
Fruit ripens in about 75 days and the husks open so it can be picked.
If the fruit detaches easily from the husk, it is ready.
I understand this unusual plant can also be used as a rootstock for tomatoes and peppers, adding disease resistance and perhaps a degree of cold tolerance since the plants survive temperatures down to 24 Fahrenheit or lower.
