Pre-nuclear potatoes are the earliest generation of potatoes. These are grown from tissue culture in our greenhouses. As these have never been grown in native soil and they are free of disease. These marble sized tubers can produce high yields of up to 200% or more by weight. These medium to extra-large tubers have smooth, brilliant red skin with medium shallow eyes and pink swirled flesh that retains its color after cooking. Like most reds, this variety is good for steaming or boiling and makes an attractive and unusual potato salad.
