Concur Rick. I have grown Minowase # 3. Definitely a fall radish. Bolts when spring planted. Tolerates frost but not a freeze. Similar to turnip. I prefer Chinese and Korean winter radishes to the Japanese. Personal favorite is Watermelon, I also like Rose Winter and Tae Baek. Watermelon does well spring planted, But I prefer to use spring space for quick maturing European types.
