Radicchio is a perennial cultivated form of leaf chicory vegetables. It is also known as Italian chicory as it is commonly used in Italian cuisine. It resembles red cabbage with colorful white-veined red leaves that form the head.
Radicchio has a bitter and spicy taste which mellows if it is grilled or roasted.
This vegetable grows best in Spring and Autumn gardens. It excels with more frequent but not too much watering based on soil type. The bitterness in the leaf is directly correlated to the frequency of watering.
The Autumn crop is more mellow due to the onset of the cold temperatures heading into Winter. The cold also encourages a more reddish color.
Radicchio matures in approximately three months. The crop can survive Winter, as long as the head is cut off carefully above ground level and protected against severe frost.
