Horseradish. Spice up your garden with this rugged and cold-hardy perennial that grows best where there's enough of a winter to force the plants into dormancy. You can choose from two widely available types of horseradish: common horseradish, which has broad, crinkled leaves, and Bohemian, which has narrower, smooth leaves and better disease resistance, though disease is very rarely a problem for home gardeners. #gardengrowingtips
