300 seeds. 30 days. Raphanus sativus. Annual.
 
Radish 'German Giant' has dark pink roots with a white interior that are 3 inches in diameter. This German heirloom is known for staying crisp even at a large size. My mother's favorite radish.
 
Sowing Radish Seeds: 
 
Sow seeds outside in early spring as soon as the soil can be worked in spring or fall. Sow on the surface and barely cover the seeds. Keep consistently moist until germination. Thin to 2 inches apart. Full sun.
