|Growing Radicchio (source)|
Radicchio, is similar to cabbage and mostly used as a salad green. It is red and white, slightly bitter and highly nutritious.
If your radicchio plants are established, they can handle a little frost. Remember, that radicchio doesn't do well in extreme heat, as it will cause it to go to seed.
Sow radicchio seeds very thinly, ¼ inch deep. Sprinkle them over the loosely raked soil, and wait for germination to take place. Usually in just a few days. Radicchio also does well in containers as long as your pot is at least 8 inches deep.
