Winter radishes are a must for radish lovers. 'Round Black Spanish', also known as 'Noir Gros Rond d'Hiver', grown in the U.S. since the 1800s, is an extra large, winter radish that adds spiciness to raw or cooked dishes; spiciness declines when cooked. Winter radishes require a shortening day length and cool temperatures to mature the edible root; sow after mid-summer and into early fall. They can be stored for long periods.

Have become a fan of all the varied coloured radishes that Botanical Interest Seeds sells, because they have become a favorite of the neighborhood kids who never were fans of salad before.

Owner Response: Hi Albert, We are sorry you had issues with this product. It sounds like the seeds performed well by germinating. As a reminder, this is a winter radish and will not form a bulbous root in spring, but instead needs shortening days (fall) to create a bulb. If you sowed these at the correct time and thinned appropriately a soil test would be helpful to understand any limiting nutrients or if there is an overage of nutrients, like nitrogen which favors leaf growth over bulb growth. Happy gardening!
