Growing some unusual veg

Looking through the seed catalogues earlier this year, a couple of unusual veg plants caught my eye.
One lot of plants were some Black Tomatoes, the others were these...


Sweet Potato plants as opposed to slips, which are supposed to be easier to grow. Here in the North I will have to keep them in the greenhouse to ensure that they grow well. It will be interesting to see how the sweet potatoes grow and the taste of the black tomatoes.
