Round Black Spanish is a 16th‑century European winter radish with inky skin and dense white flesh that keeps for months in cool storage. Flavor is sharper than spring types—grate into salads, roast wedges, or pickle slices. Traditionally valued for liver and digestive support, it’s still a tonic vegetable in winter cooking. Sow in late summer for fall harvest, thin well, and keep moisture steady to avoid pithiness. If you like assertive roots that last past Christmas, grow Black Spanish.

How to Grow

Plant spring radish seeds directly in the garden starting 4-6 weeks before average last spring frost. Optimum soil temperature for seed germination is 50-65 degrees. Since they mature so quickly, spring radishes are often planted with carrots and parsnips, between slowly growing cole crops, or between small tomato and pepper plants. Plant every 2-3 weeks for a continued harvest until about 4 weeks after average last frost. Can be sown again in early fall. Plant winter radish varieties 6-8 weeks before average first frost.

Yummy spicy radish

This one is pretty spicy but very yummy. Definitely not as black as the pictures show but maybe I harvested early.

Hello Sommer! Thank you for your thoughtful feedback on the Round Black Spanish Radish Seeds. We're pleased to hear that you're enjoying the flavorful spiciness of these radishes. It's not uncommon for their appearance to differ slightly from pictures, as factors like harvest timing and growing conditions can influence color. The spiciness you've noticed is due to compounds called glucosinolates, which are a natural defense mechanism in radishes. When radishes experience stress, like heat or nutrient imbalances, they produce more glucosinolates, resulting in a spicier taste. Harvesting radishes early, before they face prolonged heat, can indeed help manage their spiciness. If you have more insights to share or questions to ask, feel free to reach out. Happy gardening!
