Grow radishes in your garden, and enjoy delicious meals with your very own, home grown produce. Radish Radar is a large radish variety, producing round, crisp globes of bright red with white flesh. Seedlings grow quickly and can be harvested in as little as a month, and the crops can be stored for a number of weeks. A must in every garden, particularly as a row of radishes can be squeezed in as a catch crop between slower growing vegetables.
