Watermelon radish is a stunning heirloom radish (Raphanus sativus) with a pale green-and-white exterior hiding a vivid rosy-pink interior. These watermelon radish seeds grow round 2–4 inch roots that are crisp, mildly sweet, and less peppery than common radishes, adding brilliant color and gentle crunch to the plate. A type of daikon (also called Rose Heart), it's as beautiful as it is tasty.

Who it's for

For cooks and gardeners who want a showstopping, mild radish for salads and garnishes, and for cool-season growers seeking fast, colorful roots.

How & when to plant

A cool-season crop best sown in early spring or late summer for fall harvest. Direct-sow seeds 1/2 inch deep and thin plants to 3–4 inches apart in rows 12 inches apart. Full sun to part shade and loose, moist soil produce the roundest roots. Grows as an annual in USDA zones 2–11; avoid mid-summer heat, which can turn roots woody and sharp.

Harvest

Ready about 55–65 days from sowing. Harvest when roots reach 2–4 inches across; larger roots keep their color but can grow fibrous, so pull promptly.

Benefits & uses

Beautiful sliced raw in salads, pickled, quick-roasted, or used as a colorful garnish. The rosy flesh makes striking rounds and matchsticks.

FAQ

Despite the name, this is a radish, not a melon. It is a mild, slightly sweet heirloom with a pale green-and-white exterior and a striking bright-pink interior.
It matures in about 55-65 days, a bit longer than common radishes. For the best color and mild flavor, grow it as a fall crop in cooler weather.
Sow directly in early spring or, ideally, in late summer for fall harvest. Cooler temperatures produce sweeter, larger, more vividly colored roots.
Sow seeds about 1 inch apart and thin to 2-4 inches apart in rows 12 inches apart. These larger radishes need more room than salad radishes to size up.
Its crisp, mildly sweet flesh is beautiful sliced raw in salads and on platters, and it can also be pickled or lightly roasted for a milder flavor.
Each packet contains about 200 seeds of this open-pollinated, non-GMO heirloom radish, so seed can be saved from plants left to flower.
No, it's milder and slightly sweet compared with common red radishes.
Stored cool, dry, and sealed in the original packet, the seeds stay viable for a couple of years or more, with the best germination in the first year or two.
