Radish, “Rudolf” Seeds
Nothing says spring in the garden like a quick-to-harvest radish. ‘Rudolf’ has uniform 1″‒round, crunchy roots that resist getting pithy when grown in the cool weather of spring or fall. Radish greens are edible, too, and they pack a punch in salads but are also delicious sautéed. A 2008 Royal Horticultural Society award winner. Inert organic coating improves seed visibility when sowing.
