Heirloom Broccoli (Brassica oleracea var. italica), such as classic Calabrese, is a cherished garden staple celebrated for producing large, central blue-green heads packed with tight, tender florets. Once the main central head is harvested, the plant continues to yield abundant side shoots over several weeks. Delivering a crisp texture and rich, nutty-sweet flavor, it is packed with vitamins and antioxidants, making it a versatile staple for steaming, roasting, stir-fries, or fresh garden dips.
