Calabrese Broccoli seeds!
Calabrese broccoli is also known as Italian green and is the most-common variety of broccoli in the United States. Its signature main head is surrounded by several side shoots that resemble a very compact, green flower. A cool-season vegetable, calabrese broccoli is a fine fall and winter planting project that yields delicious results.
Broccoli grows best in cool weather. Start the seeds indoors 4-6 weeks before the last expected frost. Shortly before the last frost and when the seedlings reach about 6" tall, plant them 1-2' apart in rows 2-3' apart. For direct sowing seeds, plant them 1" deep and 3" apart in full sun and rich soil, about 2-3 weeks before the last expected spring frost
