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!
