Thomas Jefferson grew green, purple, and white types of broccoli on many occasions in his gardens at Monticello. Introduced to America in the 1880s by Italian immigrants, Calabrese Broccoli is a popular market variety with 5-8”, dark green heads. Smaller side shoots can be continually harvested after the main head is removed.
