How to Grow Radicchio - Italian Chicory
Radicchio, or Italian Chicory, is a gourmet type of vegetable. Native to
Italy, Radicchio grows best in cool weather.
There are both open leaf and heading varieties. Heading varieties are the
most popular. Leaves are maroon or reddish in color, with white veins. Radicchio
heads grow 3-5 inches across.
Radicchio is popular in gourmet salads, adding color and taste. It is also
eaten raw with a little olive oil. It has a crisp, mildly bitter flavor,
when it is allowed to mature in cool weather. But, it takes on a strongly
bitter taste, if it matures in the summer. Radicchio is also grilled and
