Round Black Spanish - Radish Seeds
A beautiful, zesty, winter heirloom radish with black skin and crisp white flesh. Large 2–4" round roots with crisp, hot, white flesh. Black radishes were first cultivated in the Eastern Mediterranean. They were introduced to the rest of Europe during the Middle Ages and were one of the primary root vegetables grown for their nutritional content, increasing their popularity in Europe through the 19th century. 2.5g ~ 250 seeds.
GROWING TIPS
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.

Customer Reviews
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!
