Description
Thomas Jefferson grew green, purple, and white types of broccoli on many occasions in his gardens at Monticello. Introduced to America in the 1880's 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.
Sow seeds indoors 4-6 weeks before transplanting. Move to cell-packs once they have several true leaves. Harden off and transplant just before the last frost date to well-drained, fertile soil. Tolerates light frost. Approximately 150 seeds per packet.
