Japanese sweet potatoes (Slips)- /Red Skin Yellow Flesh, asian vegetable,

Sweet potatoes, or Ipomoea batatas, originated in Central or South America and have been cultivated by humans for over 5000 years. Today, there are over 400 strains of sweet potato grown around the world. Different parts of the plant, such as the leaves, stems and root tubers, are used for food, medicine and animal feed

Japanese sweet potatoes (Ipomoea batatas)  .These potatoes can prove difficult to find, so you can grow the vines, called slips, to grow your own Japanese sweet potato crop in your garden.

Satsuma-imo, or Japanese sweet potato, is a sweet, yellow-fleshed strain. Traditionally grown in Japan and Okinawa, it is now available at grocery stores across North America. It is a staple food of the Okinawans, who are some of the healthiest and longest-lived people on Earth. Their good health and long lifespan are attributed, in part, to their diet

Nutty and mild, Japanese sweet potatoes have a thin red skin and dense Yellow flesh. They are a bit drier and more sweeter than the red skin white flesh vegetable you may also know as a yam or sweet potato. Often baked, candied or made into pies, they also make a delicious side dish when scalloped with sliced apples and a creamy sauce.

How we grow  
I have started Japanese sweet potatoes,half-whiskey barrel containers.
I got just as much yield from the container as I did from a Raised Bed, but it was so much easier to harvest the Sweet Potatoes in the container. It would take me a over an hour to dig up the Raised Bed and find all of the Sweet Potatoes. With the container, all I had to do was to dump the container onto some newspapers and the Sweet Potatoes would just appear. No digging. No hunting.

Sweet potatoes aren't started by seed like most other vegetables, they're started from slips. Slips are shoots that are grown from a mature sweet potato.

The slips need warmth, so put them on a window ledge or on top of a radiator. In a few weeks your potatoes will be covered with leafy sprouts on top and roots on the bottom

Before you plant sweet potato slips, you have a little extra work to do. Sweet potatoes need loose, well-drained soil to form large tubers. You don't want the roots to face resistance when they try to expand within the soil. Loose soil is more critical than almost any other factor when it comes to growing sweet potatoes successfully.
