Radicchio, also known as Italian chicory, is a wonderful perennial vegetable that can be a great addition to any garden. Contrary to popular belief, radicchio can indeed come back every year in most climates, as long as you don’t dig it up for blanching purposes.
One of the reasons radicchio is considered a perennial is because it has a deep taproot that allows it to survive through the winter and regrow in the spring. This taproot helps the plant establish a strong foundation, making it more resilient to cold temperatures and harsh weather conditions.
In my personal experience, I have had radicchio plants come back year after year without any additional effort on my part. Once established, they require minimal maintenance and continue to produce beautiful, vibrant leaves.
To ensure the longevity of your radicchio plants, it’s important to allow them to go through their natural growth cycle. Some chefs prefer to dig up radicchio plants to blanch them, which involves covering the leaves to restrict sunlight and promote a milder, less bitter flavor. However, this process can disrupt the plant’s natural growth pattern and decrease its chances of coming back in subsequent years.
If you want your radicchio to come back as a perennial, it’s best to leave the plants in the ground and allow them to fully mature. This will not only increase the likelihood of their return but also result in more flavorful and nutritious leaves.
In terms of climate, radicchio is generally hardy and can tolerate a range of temperatures. It prefers cool weather and can withstand light frosts, making it an excellent choice for spring and fall gardens. However, extreme heat during the summer months may cause the plant to bolt and go to seed prematurely, so it’s important to plan accordingly.
To summarize, radicchio can indeed come back every year in most climates if you avoid digging it up for blanching purposes. By allowing the plant to establish a strong root system and go through its natural growth cycle, you can enjoy this delicious perennial vegetable in your garden for years to come.
