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. Growing guide: New to this variety?
