Ketchup n Fries is a grafted vegetable plant that has a cherry tomato scion attached to a potato rootstock.  
The ketchup part of the grafted plant produced quite a few pints of tasty cherry tomatoes.
At the end of the season I harvested 4 potatoes from my Ketchup n Fries grafted plant.

Would you pay $30 for a cherry tomato plant if it promised to grow potatoes, too? After including shipping and handling, that's what I paid for one Ketchup 'n' Fries grafted vegetable plant from Territorial Seed Company.

I certainly understood why I was paying a premium for that pricey plant. After all, the tomato scion is hand-grafted onto a potato rootstock. Then there's the careful packaging to make sure a healthy plant gets to its destination. And the company was diligent about making sure it was delivered in time for planting in my region.

While the "ketchup" part of the plant grew many pints of delicious cherry tomatoes, I ended up harvesting only 4 potatoes. Instead of making fries, I boiled and mashed 'em. 

I grew the plant in a large patio container, following the instructions that came with the plant and calling to talk with a customer service representative. More detailed planting and care instructions would've been helpful, too, especially for beginning potato growers.

Perhaps the cool and wet early summer weather had something to do with such a small yield. Or maybe the plant needed more than 8 hours of sun each day. Whatever the reason, only two potato plants sprouted and grew. 

In spite of a disappointing harvest, this gardening experiment was still interesting. It proved that vegetable grafting can be a good option for gardeners, although the marketing may create unrealistic expectations.

Have you planted a grafted tomato-potato plant in your garden? If so, I'd be interested in hearing about your potato harvest.
