Raphanus sativus. Daikon radishes are large and require deeply prepared soil, as the long ones can grow to be over 30cm (12″) long. Sow and grow as you would turnips, thinning them to 15-20cm (6-8″) apart. At each cultivation, push the soil over the top of the root. Slice them for stir-fries and salads, cooking, or pickling. Flavour is milder when grown to maturity in fall, in light soil, and with good irrigation. One of the best daikon radishes for summer, Minowase Summer Cross daikon seeds have white roots that are 15-20 inches long and 2.5″ in diameter. The pure white flesh is excellent for salads, sandwiches, cooking, and pickling.
