Radish Nero Tondo 100 Non-GMO Heirloom Seeds represent an improved black Spanish radish strain that offers greater uniformity and enhanced resistance to bolting compared to the traditional Black Spanish variety. These radishes develop large, round roots measuring 2 to 4 inches in diameter, featuring a striking black skin and crisp, hot white flesh. Ideal for sowing from mid-spring when soil temperatures reach 60°F or higher and extending through the fall season, they should be thinned to 4 inches apart to encourage optimal growth. Nero Tondo radishes have a medium-long storage life and mature in approximately 50 days, with seeds boasting an 80% or higher germination rate. Grown sustainably without genetic modification, these heirloom seeds come in environmentally responsible packaging that is reusable, recyclable, and climate friendly, making them an excellent choice for gardeners dedicated to quality and ecological stewardship.
