Here’s a sweet two-for-one deal for gardeners: A single plant that grows both tomatoes and potatoes. Dubbed the “Ketchup ‘n fries” plant (I would have gone for pomatoes or totatoes, personally), this isn’t a genetically modified organism but a plant of two different nightshades: the top of a cherry tomato grafted on to a white potato.
Check out this awesome Tedx talk by artist/scientist Sam Van Aken. He describes in detail how he sculpts stone fruit trees that produce 40 different fruits through use of grafting (background from wikipedia). They also produce unique and beautiful flowering patterns. Very cool use of grafting for science, art, and food! Check out Sam’s website! http://www.samvanaken.com
