TomTato plant grows both tomatoes and potatoes

The TomTato, however, is in a league of its own – it's a single plant that produces both tomatoes and potatoes at the same time. The TomTato is not  the result of genetic engineering. It's "simply" the top of a cherry tomato plant and the bottom of a white potato plant, that have been grafted together at the stem.

While it's been possible to create such hybrids for a long time, the taste of the resulting tomatoes has apparently left much to be desired. According to the company, however, the TomTato's fruits have a Brix (sugar content) level higher than that of most supermarket tomatoes, along with "just the right level of acidity that only the tastiest tomatoes have." The potatoes are said to be fine for boiling, mashing or roasting. The TomTato is purchased as a grown plant (as opposed to in seed form), and lasts for one growing season. One plant can reportedly produce up to 500 tomatoes and 2 kg (4.4 lb) of potatoes.
