Round Black Spanish Radish is a winter-storage heirloom that has been grown since at least the 16th century, prized for its dramatic appearance and surprising versatility in the kitchen. The roots reach 5 inches across with a deep, near-black skin and brilliant snowy-white flesh inside, creating a striking contrast on the plate. Ready to harvest in 55 days, this frost-hardy variety produces a fine, fairly hot flavor that works equally well raw in slaws and salads or cooked in hearty winter dishes. It stores exceptionally well through cold months when kept in good conditions, earning its reputation as a reliable winter crop.

The jewel-like contrast between its charcoal-black exterior and pure white interior makes this radish as beautiful as it is flavorful. You can enjoy it fresh within two months of sowing, yet it also stores through winter without deteriorating, giving you months of harvest from a single planting. Its fairly hot, fine flavor works raw or cooked, and it's genuinely frost-hardy, thriving even as temperatures drop in fall.
Round Black Spanish Radish shines as a winter vegetable, whether thinly sliced raw into salads and coleslaws for its peppery bite, or roasted and braised into warming winter dishes where its heat mellows into a mellow, earthy sweetness. The dense flesh holds up beautifully to cooking without turning mushy, and its mild spiciness complements both European and Asian preparations. Because it stores so reliably, it became a staple in root cellars and cool storage, offering fresh radish flavor well into spring when other vegetables were unavailable.

Sow directly outdoors 8 to 10 weeks before your average first fall frost date. Optimal soil temperature is 65 to 85 degrees Fahrenheit. Sow successively every 10 days for about 3 weeks; in mild climates, continue successive sowings until temperatures drop below 60 degrees Fahrenheit.
Harvest Round Black Spanish Radish approximately 55 days after sowing, though some sources indicate it may take up to 70 days depending on conditions. The roots are ready when they reach about 5 inches across; you can carefully brush away soil to check their size without pulling them. Because this is a frost-hardy variety, you can leave mature roots in the ground and harvest as needed through fall and early winter, or pull them all at once and store for later use.

“Round Black Spanish Radish likely emerged in southern Europe, particularly the Iberian Peninsula, where black radish varieties have deep roots in traditional agriculture. References to this cultivar, known by its French name Noir Gros Rond d'Hiver, suggest it has been in continuous cultivation since the 16th century or earlier, passed hand to hand through gardeners and farmers who valued its storage potential and resilience. The fact that it survived and spread across centuries speaks to its utility in an era when winter vegetables were truly precious; this was a radish that could sustain families from autumn harvest through spring.”
