60 Days to maturity. Raphanus sativus. Green Meat Luobo Chinese Radish Heirloom Seeds. Cool Season Annual. Unlike other Chinese radishes, Green Luobos aren’t globe-shaped—instead, they grow as big as 10” long! Another way they differ is their bright green flesh which looks almost like a cucumber. They are as sweet and crisp as other varieties but can have more bite if allowed to grow. Plant them in late summer and harvest pain-free in the fall. This variety produces uniform roots that are great for storing! ~ 2,100 seeds / oz.
