Red Radicchio

Radicchio (Cichorium intybus) is a perennial plant in the chicory genus that falls within the Asteraceae/Compositae (aster) family that includes the daisy and dandelion, amongst other composite flowers. This cultivated version of chicory, sometimes called red or Italian chicory, is a beautiful burgundy color leafed vegetable with white veins. Hailing from Italy, radicchio comes in several varieties that are usually named for the area of Italy they originated from.

Benefits of Radicchio

While more intentional cultivation began in the 15th century, radicchio has been used as far back as ancient Roman times. It was administered medicinally to treat problems such as insomnia or to be used for blood purification. The idea of treating insomnia comes from the fact that radicchio contains lactucopicrin (intybin), a sesquiterpene lactone (which is found in most of the Asteraceae family). This compound is what gives radicchio its bitter taste but also acts as sedative and an analgesic. Plus, it has been used as an anti-malarial agent and is known to reduce hunger pains. As for its blood purifying capabilities, this may also be due to the sesquiterpene lactones radicchio possess, because they also reduce inflammation, suppress tumors, and promote microbial and parasite resistance.

Radicchio also provides many phytonutrients/antioxidants such as lycopene, zeaxanthin, lutein, ellagic acid, and quercetin, which improve overall health, reduce inflammation, and reduce the risks of developing chronic diseases and certain cancers. Radicchio also has inulin; a soluble dietary plant fiber and oligosaccharide that helps regulate blood glucose and promote a healthy gut biome.

For a 1 cup (40 grams) serving radicchio provides 9 calories, no fat, 1 gram of protein, and 2 grams of carbohydrates. This leafy vegetable is an excellent source of vitamins C, E (Alpha Tocopherol), K-1, B-9 (folate), and copper, manganese, and potassium. It is also a good source of vitamins B-5 (pantothenic acid), B-6, iron, magnesium, phosphorus, and zinc.

Growing Radicchio

With all the health benefits this lovely red chicory offers, it’s a wonderful, and beautiful, addition to your garden. Radicchio can be grown in both spring and fall; however fall crops result in higher quality produce and radicchio isn’t very tolerant of long days or hot summer temperatures. Both will cause the bitterness of radicchio to intensify, and may also increase its chances of bolting and burning. So, while a spring crop is doable, just know that radicchio has a long growing season of up to 90 days and will be green in the hotter part of summer, turning red in the coolness of fall.

When planting radicchio, sow in full sun (although it is partial shade tolerant) in soil that has pH around 6, with low levels of nitrogen. Plant seeds about ¼ inch deep in rows that are spaced at least 2’ apart. Thinning can be done once the plants emerge so that plants are 6” apart. It’s best to water plants thoroughly once a week, ensuring that deep watering is conducted 1-2 weeks prior to maturity. Once your radicchio has matured and you’re ready to harvest, you can pick the entire head or just a few leaves at a time.

As the plants grow keep an eye out for aphids that can damage plants. Inviting ladybugs into your garden can help keep aphid populations at bay. If you find you can’t keep aphids from taking over your garden, try mixing 5 drops of the essential oils thyme, peppermint, clove, and rosemary and adding them to a spray bottle filled with water and spray your radicchio. Using hot pepper or capsaicin can also work, just do not inhale or get into your eyes!

Cooking with Radicchio
