Softball-size (claim to 4 lbs.), orange-red fruits with consistent size and shape. Good flavor: lively initial burst, then balanced, somewhat mild, but tasty. Potato leaf, determinate (though listed as large) vines; impressive yield from 78 days. History is intriguing: Joe Roberts was a paratrooper during World War II (thus the name), landed in a field of tomatoes, saved some seeds, grew them for decades and the rest is history. A variety little known and rarely grown.
