A plant that produces both tomatoes and potatoes, called the TomTato, has been developed for the UK market.
Similar plants have been created in the UK, but the firm said it was thought to be the first time they had been produced on a commercial scale.
Not surprising, actually. They're both part of the same family, including such notables as belladonna and eggplant, as well as the chili peppers (capsicum).
Potato and tomato plants can grow as one in the home garden.
Most fruit and vegetable plants of the same family, including potato and tomato plants of any variety, can be grafted to create one plant. The upper part of the graft becomes the top of the plant and produces tomatoes, while the lower section or root system will produce potatoes. This method of grafting is a common practice for gardeners who don't have a lot of space to work in; however, a grafted plant will yield much less than two plants growing separate. Grafting is best done with two healthy plants that have stems of similar diameter.
Although a potato and a tomato cannot be cross-bred, it is possible to graft together a tomato plant shoot to the rootstock of a potato plant. The grafted plant will produce both tomatoes from the tomato shoot and potatoes from the rootstock. Grafting together the two plants can save you space in the garden and make a tomato plant grow that is not well suited for the soil in your garden. Be aware that the grafting together of the two plants can effect the taste of the fruit.
Cut the stem of the potato plant so that it is split into a "V" shape. Cut the stem so that about 1 inch is exposed above the ground.
Cut the roots from the tomato plant, making a cut on the stem that is straight across using a sharp knife. The cutting should be about 6 to 8 inches long.
Cut the tomato stem so that it looks like a wedge shape by cutting material off both sides of the bottom of the stem. Make the cut so that it fits into the "V" shape cut into the potato plant stock.
Slide the two cut pieces together.
Wrap the graft with grafting tape so that the cut holds. Remove the grafting tape once the plants begin to show new growth.
Tomacco would probably be a difficult cultivar to harvest since both tomato and tobacco are above-ground harvests. Potabacco is a more likely harvest.
My friend was telling me about this yesterday. It's only a matter of time now before someone actually cultivates the tomacco.
I had an idea once for ketchup-centered French fries. This is almost as good! I'm going to try one!
For some reason i thought a lemon and a lime mixed together would be mind blowing! A limeon! MUAHHAHAHAHA Id make millions.
